Dim objStreamWriter2 As StreamWriter
Dim DTString As String

    DTString = "C:\\ETCLINK\\" + Convert.ToString(Date.Now)


    'Pass the file path and the file name to the StreamWriter constructor.

    objStreamWriter2 = New StreamWriter(DTString) 

I take a runtime error when the code is run. What is the problem? Thank you? (objStreamWriter2 = New StreamWriter("C:\ETCLINK\09042008121212.txt") no problem here

I have a dialog and this dialog's domodal function(myDlg->DoModal) is called from another cpp file. I got rectangle of this dialog at the end of the oninitdialog function and a button clicked event after the dialog had been visible but these two rectangle values were different. Does domodal function do something about position of the dialog after oninitdialog function of this dialog? other.cpp: myDlg->domodal() myDlg.cpp: myDlg::OnInitDialog { //other code ...... ...... GetWindowRect(&rect); // top=29 bottom=221 left=165 right=1033 //end of function } myDlg::ButtonClick //i clicked button while the dialog was on the screen { GetWindowRect(&rect); // top=431 bottom=623 left=407 right=1275 } Why are these two rectangle diffenrent? Thanks.

I have lots of dialogs in my application and these dialogs are used with 1600 1200 resolution. Now, this application is ready to use but i want to run it with different resolutions. I wrote an different application(or function or class with function) to do this and it sets all of controls' size of a dialog as resolution but for only one dialog. How can I apply this solution for all my dialogs? For example May all of my dialogs inherit from my new class(is it a good solution) or what else? Please help.

There is a dialog and it has more than one controls.I want to get all these controls to set or change some their properties at runtime. To do this , i use that code. CWnd* pChildWnd = wnd->GetWindow(GW_CHILD); while ( pChildWnd ) { // other code here pChildWnd = pChildWnd->GetWindow(GW_HWNDNEXT); } But i can't get controls and this while loop enters infinite loop. Please help me to get all controls. Thanks.

You want read only datagrid or no selection on datagrid text? Because, you can also select text on read only datagrid.
