• remedios_ Form paint while OnLoad processing ...?

  I have a form with various controls on it. I have some code that runs on the form's OnLoad event, but while that code is running, the form doesn't fully paint itself. There's got to be something I'm missing to tell the form to go ahead an draw itself regardless of running code. Any pointers appreciated. Thanks in advance! How about assigning your processing part to an asynchronous "background worker" (.NET 2.0) Hi this is due to the fact that the code that is processing is done on the form thread. if the code you are processing takes a long time, and you need to display the form before the code is run, you should use an asynchroneous approach: - backgroundworker example http://msdn2.mi ...Show All

• billcoke How to organize a field with "Last changed date/time"?

  I have a field in my datatable to record the last date/time the record has changed. My problem is how to update this field programmatically. When I use the TextChanged event of a control, this also fires when the record is accessed. I have tried to use the DataTable.Rowstate, but also this is modified when I don't make any changes. With a DataGridView I have no problem, only with the detailView. Who has a suggestion Or should the rowstate work, but is the something else that causes this modified state Maybe the use of a flag to indicate that a process to modify has been performed by the user solves this issue. This flag can be set to true only when the user press a button or link to modify an spe ...Show All

• SaloS String with color

  Hi all, Anyone knows how to put some color to string output For example, I have this output in my listbox: string value1; string value2; myListbox.Items.Add(String.Format("{0} - {1}", value1, value2)); and now I want to color value1 red and value2 blue. How can I do that Idea/suggestion are very much appreciated. Regards. You need to make your listbox ownerdraw, list box items don't have colors, I don't think. Hi, The string itself will not record the information of color. It's the responsibility of its container to draw the color. Here is an example, but if you want different color in one item, you need make the effort to draw it by youself. private void For ...Show All

• parlance Forms in different dlls needs to communicate

  hi, I am fairly new to Visual Studio (2005, c++) and I have a large application that needs to be ported to this plattform. Most of the application we need to rewrite from scratch (as it contains very bad code). But since this application is large, I need to devide it into several dlls (assemblies) and I also need to put forms in the dlls. I have tried to search the Internet for this, but I can't find out how the forms can communicate with eachother! Do you understand my problem Well, I have three dlls; A,B and C. In each dll I have one form AF, BF and CF. AF is a mdiparent and BF and CF are childs. This works and I can show them and operate with them, but I cant get BF and CF to send data to eachother.

• szolDat Updating an unbound DataGridView at Runtime

  I am a beginner programmer, so please bear with me. Say you have a DataGridView. You dock it to a Window Form. You set some properties such as AllowUserToAddRows and AllowUserToDeleteRows. So far, so good. Now, according to MSDN, a DataGridView can be eighter bound to a Data source, or it can be used as is. If it's not bound, you simply add rows, fill them with data and it should work just fine. My problem is this. I build the solution, add a Setup project to it and then I deploy it ( that is, install it ) on my machine. Now, I open the application and start populating the rows with data. Everything is fine. I close the application. When I open it again, bingo! All the data is gone. There must be some king ...Show All
