Edit and Display Boolean Fields using a CheckBox in Delphi

Tip submitted by Rene van der Heijden A series of articles titled Adding components to a DBGrid discusses placing just about any Delphi control (visual component) into a cell of a DGBrid. The idea is to create visually more attractive user interfaces for editing fields inside a DBGrid: a ComboBox for drop down lists; a DateTimePicker (calendar) for date values; a check box for boolean fields. CheckBox for Boolean Fields CheckBox inside a DBGrid As noticed by Rene van der Heijden the solution is rather lengthy, and it doesnt work, at least not when using the mouse to click on the checkboxes. Rene suggest an easier approach needing only two even handlers: OnCellClick and OnCustomDrawCell for your DBGrid control: //OnCellClik event of a DBGrid1 procedure TForm.DBGrid1CellClick(Column: TColumn) ; begin   Ã‚  if (Column.Field.DataTypeftBoolean) then   Ã‚  begin   Ã‚  Ã‚  Ã‚  {toggle True and False}   Ã‚  Ã‚  Ã‚  Column.Grid.DataSource.DataSet.Edit;   Ã‚  Ã‚  Ã‚  Column.Field.Value: not Column.Field.AsBoolean;   Ã‚  Ã‚  {immediate post - see for yourself whether you want this}   Ã‚  Ã‚  Ã‚  Column.Grid.DataSource.DataSet.Post;   Ã‚  Ã‚  Ã‚  {you may add additional functionality here,   Ã‚  Ã‚  to be processed after the change was made}   Ã‚  end; end; //OnDrawColumnCell event of a DBGrid1 procedure TForm.DBGrid1DrawColumnCell(   Ã‚  Sender: TObject;   Ã‚  const Rect: TRect;   Ã‚  DataCol: Integer;   Ã‚  Column: TColumn;   Ã‚  State: TGridDrawState) ; const   Ã‚  CtrlState: array[Boolean] of integer (DFCS_BUTTONCHECK, DFCS_BUTTONCHECK or DFCS_CHECKED) ; begin   Ã‚  if (Column.Field.DataTypeftBoolean) then   Ã‚  begin   Ã‚  Ã‚  Ã‚  DBGrid1.Canvas.FillRect(Rect) ;   Ã‚  Ã‚  Ã‚  if VarIsNull(Column.Field.Value) then   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  DrawFrameControl(DBGrid1.Canvas.Handle,Rect, DFC_BUTTON, DFCS_BUTTONCHECK or DFCS_INACTIVE) {grayed}   Ã‚  Ã‚  Ã‚  else   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  DrawFrameControl(DBGrid1.Canvas.Handle,Rect, DFC_BUTTON, CtrlState[Column.Field.AsBoolean]) ; {checked or unchecked}   Ã‚  end; end; Delphi tips navigator: » Remove Duplicate Items in Delphis TStringList « 5 Facts you Did Not Know about Delphi and Classes and the VCL and Inheritance and Custom Controls and...

A Risk Assessment - 1947 Words

This assignment will take the form of a risk assessment, assessing the possible risks that can be found in the home environment and its surroundings. It will define what is meant by the word risk and it will describe how one is identified. In the essay, three risks from within the home will be examined and there will be a discussion as to how frequently these risks occur. Penultimately, this essay will present influential criminological theories to help explain the phenomenon of crime. Finally, it will suggest useful means of crime prevention before concluding that suitable methods of prevention can, in fact, reduce the likelihood of certain victimisation. Within the field of criminology, a risk is referred to as the ‘probability of†¦show more content†¦Gately et al. (2014) state that many offenders would not attempt to carry out a burglary on a house which ‘looked reasonably secure’. This suggests that security cameras may be seen as a deterrence to criminals. It is also notable that victims of burglary often experience repeat victimisation. This is when the same location, business, vehicle or household suffers more than one crime event over a specified time period. The offence may be the same or a contrasting type (McLaughlin Muncie 2013, p.377). One reason for this is because offenders know that victims will often replace what has been taken by an insurance claim. Strain theory could provide an explanation as to why an individual may carry out a burglary. The theory developed by Robert Merton in 1968 presents that humans are relatively good. However, certain situations drive an individual into doing bad things. Merton, (1968) argues that people who cannot achieve socially approved goals through legitimate means will do so illegitimately because of the strain that they feel. Merton, (1968) uses the American Dream to illustrate this. The American Dream emphasises money, as well as success and individuals, are expected to achieve this through education and hard work.

Reflective Learning in Professional Technology †MyAssignmenthelp

Question: Discuss about the Reflective Learning in Professional Technology. Answer: Introduction: At the time of pursuing my graduation degree, I had to consider my area of interest. Since information technology and computer is my area of interest as well as area of expertise, hence the adoption of information technology as a career option was a right decision for me. ICT is the bass of all things and ICT skills are necessary for improving the creativity and reasoning power within an individual. The ICT and the computing sector are changing radically and all the companies both private as well as the public sector are recruiting graduates with effective ICT knowledge. Hence, considering the future prospective and future career growth I found that it is advisable and profitable to take ICT as a career option (Arnold and Boggs, 2011). PIIT was a reliable option for me because the college offered diverse ICT courses on computer engineering, electronics engineering, Information technology, automobile engineering and mechanical engineering. Although I focused earlier more on choosing core-engineering subjects as my field of study, however PIIT helped me by offering me other options as well. The university professors suggested me to opt for professional issues in ICT. My choice of opting for the subject Professional issues in ICT helped me to gain knowledge about the professionalism that makes an ICT person successful. Moreover, this course helped me to understand the importance of law and ethics in the context of the ICT professions. This unit helped me to link technical aspects of my degree along with the interpersonal skills required in a job market. Hence, I can conclude by confirming that after opting for this degree I have been able to recognize the importance of interpersonal skills that will help me in being a successful professional in future. Positive workplace behaviors contribute to the development of congenial working environment for the ICT professionals. For an ICT professional it is important to maintain a gender-neutral organizational culture. Moreover, for an ICT professional it is important to have diverse working skills. The ever changing organizational scenarios requires the ICT professionals to possess skills like project management, problem solving, technical, coding and programming and business management skills.For a sound team performance I contributed in the following manner Making contribution of new ideas Listening to the team members views and respecting their opinions Offering and accepting constructive criticisms in order to develop the workplace behavior and to integrate a cohesive group work Act as a leader as well as a group member contributing in both ways Avoiding any discrimination on the grounds of gender, religion or ethics However, for making the group work more productive I feel it was necessary to know the group culture and try to reduce the gaps between the diversities that exist in terms of ethnicity, age, gender and cultural backgrounds. Moreover, I feel to make the group work easier it is essential that all members within the group are comfortable and friendly with each other. By reducing the communication gaps and creating a comfortable and friendly environment, I can contribute t the overall development of my teammates (Leung, 2011). The roles of ICT professionals may vary in different organizations. The roles generally vary from managerial roles to technical roles. Some of the important roles that the ICT professionals are required to maintain are the role of a team leader, project manager, technical assistant and the role of a team worker. These are some of the important roles, which help in completion of projects successfully (Leung, 2011). Apart from these roles, the management of customer queries in respect of ICT tools is also an important role that the ICT professionals execute. In this regard, the ICT professional needs to support customer relationship management. In some of the organization ICT professionals are also required to issue loan, IT equipment and consumables to the customers and also keep a record of the stock levels for the It products. The ICT professionals with the technical knowledge also focus on improving the websites and user guides of the IT tools in an organization. The diversity within the roles of ICT in the industry will help me to develop my career growth form a fresher to a higher position within the industry. With the development of my professional skills indifferent areas like technical, good communication and teamwork skills, management skills and problem solving ability will help me in future to make a secured job within any organization and help me to work effectively within a group. Small tech business deals in the software development in communication industry, which handles projects in Australia and overseas, namely US, Europe, Africa and South America. The company uses the ICT applications to benefit people and business. However, the company faced challenges in credibility of the information, financial support in ICT tools, and availability of appropriate resources, growth rate and change of directorship. However, from this issue I have been able to analyze the fact that the change in ICT tools with the change in the organizational cultures and organizational growth is important for a company to avoid challenges and survive successfully. Moreover, the issue has taught me to be open-minded and has taught me the lesson that every aspect of the organizational problem will not be solved. Moreover, the discussion within the issue helped me to understand the use of Golden circle. The Golden circle suggests that the professionals within the organization should have the answers to three basic questions namely what they do, how they do and why they do (Leung, 2011). Hence, as an ICT professional the understanding of the basic norms within the organization will help me to be a productive employee of the organization. However, the success of the organization can be ascertained by the increased reputation, maturity and financial security of the organization. The issues and the adoption of the different techniques will help me in generating professional skills as a successful ICT professional. The use of mobile devices in workforce has helped the organizations in improving the customer service; maintain an easy access of the historical records, guarantees that activities are performed on schedule and eliminate any problems in respect of data entry and data storage. This presentation has helped me to realize the importance and benefits of the ICT tools by displaying the benefits of the mobile devices. Use of paper-based systems before the invention of the technology gave rise to various problems namely high possibility of human error, double entry of data, non-maintenance of standard answers, project-scheduling issues, limited reporting and high labor-intensive procedures. Hence, this lecture was effective in creation of awareness of the benefits of ICT tools within the organizations. I was personally able to recognize the features like barcode scanners, telephone functions, wireless internet browsing, came, speech to text capabilities and mobile printing will help the orga nizations and the professionals to make the work easier and productive (Arnold and Boggs, 2011). The displaying of the benefits of Mobile devices in the workplace also helped the audience to acquire practical knowledge and experience form the lecture. Moreover, the lecture provoked the audience to avail the use of the ICT technologies effectively in order to reduce human labor. The lecture focused on the young ICT professionals and helped them to take ICT tools like mobile device as an important and supportive tool for the effective management f the organizational services. The lecture also focused on the digital computerized field service management system so that the young ICT professionals would be well knowledge about the ICT technology process. This lecture deals with the assessment of the professional issues in the stakeholder engagement for five different companies namely the National domestic Airline, Oracle, government departments, government portal and online supermarket shopping companies. The lecture focuses on the stakeholder engagement strategy of each company separately. From the discussion on the stakeholder engagement strategy of National domestic airline, I can conclude that to make an effective stakeholder engagement the company adopts the involvement of the all team members. Again, stakeholder engagement in Oracle is done with the development of appropriate communication skills. The lecture helps me to realize the value of listening skills in respect of improving the stakeholder engagement. The government department of Australia and New Zealand uses the stakeholder mapping as a process of identifying the people or organizations that may have an important impact on the project. However, my.gov.au adopts a diff erent aspect of stakeholder engagement. The stakeholder engagement system can make the organization beneficial in respect of meeting the required objectives. It can also enable the stakeholders to communicate keeping in mind the cultural sensibilities and interactions. The online shopping companies focus on the use of the software and IT applications on the stakeholder engagement. This lecture has helped me to understand the usefulness of IT in delivering and acquiring systems. The online shopping companies are focused on using the ICT tools for the management of the customer reviews and referrals so that their product can be serviced effectively. ICT in a developing country This lecture focuses on the use of ICT in developing countries. The focus of this lecture is on the use of ICT tools by the NGO named World Vision. The lecture at the beginning gives details about the NGO, which is a Faith based Organization operating in 97 countries with around 44,000 employees and a global income ranging of around 2.6 billion USD. The NGO woks for activities like providing relief, development of underprivileged communities, advocacy of social issues and work against trafficking issues From the lecture, I have been able to get an insight on the implications of global ICT on the activities of the NGO. The NGO has developed a global network with a connectivity of 6 Gb bandwidth however the company has no private global network. From the lecture, it is clear to the audience that the ICT tool helps the NGOs to develop education, communication and business opportunity (Arnold and Boggs, 2011). The lecture shows that ICT is an essential and significant part of the infrastructure of the companies in a developing economy. Many developing countries are focusing on new economy and supporting global demand for ICT. Thus, the lecture has made me realize that it is important to develop effective ICT skills so that I can work as a successful ICT professional in the developing as well as developed countries. The extensive use of ICT tools in companies like NGOs shows that ICT has a positive impact of the growth and productivity of the organizations. References Arnold, E. and Boggs, K.
