Are you making the setup from your debug or your release version?

If you are making it from debug, it probably is the reason why in some machines does not work. They probably are machines where visual studio is not installed, and so your program is missing the needed libraries and dlls to be able to run the application.

What error do it appears in the machines where it is not working?

As I said, if you do the setup from the debug version and you try to run the application in a machine where no visual studio is installed... you may have problems. The debug versions sometimes need to have some DLLs and other files in the target computer to run correctly.

Take a look with the dependancy-walker about what your programm needs when it is running and add it to the setup packet.

Or do the setup with released version. If you do this, I strongly recommend to take a look into:

Are you including visual studio runtime library in your setup? The Target machine may not have these files

If you go through MENUITEMINFO structure (which is used in InsertMenuItem() function) you can find fMask member which supports MIIM_CHECKMARKS value.

Hi...

Hi i am having a multiline text box.

Initially i have some data in edit box. Then if i add any data, the previous datas are gone. i want both previous and current data.

For example, I am Having "This is Test \r\n This is multiline text box".

if i add "This is second line", the editbox should show both data.

How to do...

Please help me.

I used,

CString str1 = "Some String"; 
GetDlgItemText(IDC_EDIT1, str);
str2 = str+str1;
SetDlgItemText(IDC_EDIT1, str2);

Please tell me is there any otherway....

You can try EM_REPLACESEL message.

CString cs;
GetDlgItemText(IDC_EDIT1, cs);

SendDlgItemMessage(IDC_EDIT1, EM_SETSEL, cs.GetLength(), cs.GetLength());
SendDlgItemMessage(IDC_EDIT1, EM_REPLACESEL, 0, (LPARAM)_T("Some String"));

OK you modified that post. While I thought the EM_REPLACESEL itself was a great idea, I wouldn't have liked the usage of GetDlgItem() call. But hey, different people, different ways. (why I don't like GetDlgItem()? Because I'm a terrific fan of Dr. Joseph Newcomer, and his philosophies and I take 'em seriously).

Added: Look at my second answer to the OP. Smile | :)

Me too don't like to use GetDlgItem(). It is always better and clean to use binded members with DDX/DDV. I thought I would provide an answer which resembles the sample code segment in the post Smile | :)

. Thanks for the comment.

You do realize, of course, that DDX_ macros internally call GetDlgItem? Newcomer's screed on the subject overlooks that fact. It really comes down to personal preference in coding style; one way is no more evil than another. Personally I try to avoid MFC-specific API's where possible - it makes porting code between frameworks a little less painful.

Use a control type member variable for the edit control. Then do something like

m_Edit.GetWindowText(szTemp );
szTemp += _T("Whatever");
m_Edit.SetWindowText(szTemp);

Hi,

You might want to try this (thanks to Rejeesh for his EM_REPLACESEL suggestion, which triggered this idea)

int len = m_Edit.GetWindowTextLength(); //find the length of text in the control
m_Edit.SetSel(len, len, 0);     //select nothing (but the cursor goes to the end)
m_Edit.ReplaceSel(szNewText);   //new text will be printed at the end now!

}

THis function get called as follow
CTrans tData;
CMainFrame* tFrm = (CMainFrame*)AfxGetMainWnd();
for(i=0;i<LiveDataCount.Count;i++)
tData.m_sData.Insert(i,LiveArray[i]);
