• Windows Forms Finding edited rows in DataGridView

  Hi, In my windows application I am using DataGridView as my grid control. I populated let's say 10 rows of data and modified 3 random rows. How can I trap those 3 modified rows without going through the whole row set The DataSource of my grid is a DataView which I create it programmatically. I tried this event: void GridView_CellValueChanged( object sender, DataGridViewCellEventArgs e) { int col = e.ColumnIndex; DataGridViewCell cell = _form.GridView[col, e.RowIndex]; DataGridViewRow row = cell.OwningRow; DataRowView originalRow = ( DataRowView )row.DataBoundItem; // if the fifth column was edited if (col == 4) { if (originalRow.Row.ItemArray[0] != cell.Value) { // save the change ...Show All

• Visual C# idle detection ...

  I am developing an application with multiple forms and user controls embedded in panels. After an idle time interval – by that I mean an interval of time when the user does not interact with the application - I would like to launch a form. The stupid way of doing this would be to create a method to manually restart the timer time interval and then explicitly call that method from all “click-handlers” of all form components of all forms and user controls …. I don’t want to do it that way. What is the nice way of doing it, what message/event should I capture to restart the timer interval only from one place Thanks for your help, Dom. Check out Application.Idle , it raises "when the appl ...Show All

• Windows Forms allow user to select which files to install

  Hello, I need to create a setup and deployment in vs2005 that will allow the user to select which executables (I have 4 executables) to install. Can anyone help me get started. Thanks, Michael If you go to the User Interface view, right click Start under Install you can add a Dialog. The one you want is CheckBoxes (B) I think, because it has 4 checkboxes. Add your text, then when the user checks one of them the property CHECKBOXB1 (or CHECKBOXB2 and so on) will have a value of 1, so install a file with the condition CHECKBOXB1=1, CHECKBOXB2=1 for the other file etc. ...Show All

• Visual Studio MORE INFO - Reportviewer "report is being generated" can't display report - VB 2005 program

  I have a VS2005 Windows application that displays a reportviewer (SQL 2005) report in a tab control, then displays a second report in a second tab with reportviewer, and so on. The really strange thing is that I had this application working for about 3 months. I even had up to 30 reports in 30 tabs at one point. BUT, for some reason now all I get is the first report and the second, third, etc. tabs show a reportviewer with "Report being generated" that never displays the report. Even worse, another user is able to run this application and DOES get all the reports displayed. So what could have been updated on my PC that is causing this problem Thanks in advance. P.S. I also posted this on the SQL Server 2005 forum, b ...Show All

• Visual Studio Tools for Office Problem with locking documents.

  I am trying to automate some letters. For example, I have a drop down box used to select the type of document I want. The document will then load, with tags where customer information can be added. By entering a customer number, a DB is searched and returns and fills in all of the information. There is then an option to create an image of the final document. All of this works fine, except in one instance. If I were to select one type of document, complete and image it, and switch to a new type of document, and image it, the image becomes locked and will not unlock. This is not a problem if I do not switch between different letters. Anyone have any ideas Given this isn't a VSTO specific question you'll pro ...Show All
