how can i send a clist of cstring elements to another process using writeprocessmemory?
when i try to send the list, the list is getting copied in the dest process but i cannot access its elements (i think the elements dont get copied).
thanks

Why did you use such a function (Did you considered the Clipboard for such operations)?
Are you aware that, generally speaking, pointer cannot be shared by different processes?
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Is WriteProcessMemory() really the interprocess communication
method you want to use?
Interprocess Communications[^][^]
Regardless, you need to serialize the strings into a byte stream somehow
and send that stream. The receiving end needs to de-serialize the byte
stream back into a list of CString objects.

WriteProcessMemory[^] is generally used by debuggers. I'd look for another IPC method if I was you.

Perhaps the CreateFile[^] function will help. Here's a quote from MSDN:
Creates or opens a file or I/O device.

Why didn't you use similar code in following options and instead of 0/1 use
SW_HIDE/SW_SHOW.
also as sudhir has already suggested you are every time creating dialogs in SelChange notification.
you can move them to InitDialog as suggested by sudhir.

I have cleared some doubts regarding combo box in one of my earlier threads.Had got the solution too.I have a new problem..
I have two dialogs as I told before.there is a combo box in the first dialog.i have a text box in the second dialog.when i click a button, i get the second dialog in which the text box is present.i get the data in the text box in the combo box when i click the ok button .have written code for that.my problem is , i have to see all the data that i enter in the text box in the second dialog into the combo box in first dialog.now what happens is, i can only see the last entered item.i have written it i the OnOK function ,but have commented CDialog::OnOk();
I need to enter details as long as i want and see them all in the first combo box. what to do?
Code in second dialog:
CString i;<br />
fstream f;<br />
f.open("C:\\myfile.txt",ios::app); <br />
printf("\n");<br />
<br />
GetDlgItemText(IDC_EDIT2,str_name);<br />
f.write(str_name.GetBuffer(str_name.GetLength()),str_name.GetLength()); <br />
f<<endl;<br />
<br />
m_combo.AddString(str_name); <br />
<br />
m_edit3.SetWindowText(_T(""));<br />
f.close();
in first dialog:
Add cd;<br />
cd.DoModal();<br />
<br />
m_selcam.AddString(cd.str_name);

projectip wrote: m_combo.AddString(str_name);
Which combo box variable is this.
for adding multiple strings you can create a modeless dialog and use SendMessage(..) to parent dialog
to add strings.
I hope it makes sense.
projectip wrote: Add cd;
cd.DoModal();
and you are able to see only one string because
projectip wrote: m_selcam.AddString(cd.str_name);
this will execute only when DoModal() will return.

Sandip.

Hi,
Why ShellExecuteEx is suggestible to use over CreateProcess,WinExec in Vista. What is the disadvantage if I still continue to use CreateProcess,WinExec in Vista.
Thanks,
