Create two member functions for you dlg class.
Eg.
void CTestDlg::OnOK()
{
}
void CTestDlg::OnCancel()
{
}
Enough... Go and press any key in ur dialog... it wont close (even ur close button too;))
To close ur dialog Add OnClose() Message Handler to your dlg class
void CTestDlg::OnClose()
{
EndDialog(0);
CDialog::OnClose();
}
now press you close button. It will close

Fiends,
I got a child dialog box. Problem is that on pressing the enter key the dialog disappears. What i want is that on pressing the enter key, some button on the dialog gets pressed. How can i do so.

well you could set the focus on that button, when pressing enter that will activate it.
Other way is capturing the WM_KEYDOWN message in pretranslate func and check wParam for VK_RETURN.
Hope this helps you...
Regards,
Davy

Cwnd::SetFocus();
if you use this into OnInitDialog(), you should switch its return value to FALSE.

Hey,
I have a couple of combo boxes, and When they hit new in the menu, I want it to clear, but when I use the m_varible.clear() command, it only clears the one I have highlighted or the last one I selected.
How do I get it to clear all of them?
Here is the code:
<br />
void CDEPDlg::OnFileNew() <br />
{<br />
m_type1.Clear();<br />
m_type2.Clear();<br />
m_type3.Clear();<br />
m_type4.Clear();<br />
m_type5.Clear();<br />
}<br />
<br />
Thanks for any help

Try this
extern CComboBox* pmyComboBox;
for (int i=0;i < pmyComboBox->GetCount();i++)
{
pmyComboBox->DeleteString( i );
}

Thanks guys that worked.
How about an editbox, that is ready only, and it displays the text of a combo box, I tried the clear() function there too, but it doesn't work.
Any ideas?
Thanks

Hi,
<br />
MyEdit.SetSet(0, -1);<br />
MyEdit.Clear();<br />
<br />
SendMessage(MyEditHwnd, EM_SETSEL, 0, -1);<br />
SendMessage(MyEditHwnd, WM_CLEAR, 0, 0);<br />
HTH

use this code...
void CDEPDlg::OnFileNew()

I have two dialog boxes dialog1, dialog2. One is the login.
how to pass the user and password from dialog1 to dialog2?
Visiual C++
Any hellp will be greatly appreciated
|

If you are using MFC.
You could store your password or other data to your CWinApp
And you could just call
((CYourApp*)AfxGetApp())->m_strPass ;
Or you could consider bad coding design but easier(my opinion)
global variable through
extern LPCTSTR g_YourPassword;
There are plenty of ways to do it. However, when you are storing sensitive data, you need to be more precautious in your design like consider encryption and etc.

Basically what I want to do is drop a DLL from an executable. How exactly would I go about doing this. I was thinking about having the DLL as part of a resource file. I have no idea on how to do this. If anybody has source code, please post it.

Delete your *.sln file. (only do this if you do not depend on it to load your multiple projects)
rename your file *.vcproj manually in window explorer.
Then, open your renamed *.vcproj in VS IDE.
In your solution explorer, right click on your proj node and select rename.
(I guess this is not simple enough though)
There is another way to do it as well. If your project name is unique throughout your files. Use Find and Replace - Find In Files in your IDE to replace all the name in all your files. But this way is a bit risky.
(I hope there are easier ways to do it)

Hi, Anthony, thank you for reply. i m trying to use the one u suggest. but the code is hard to understand.
in case, i really dun know how the parameter "myPort" which in etAddressLptPort GetAddressLptPortInTheRegistry GetAddressLptPortInTheMemory
hv been used.
u have any idear abt it.
btw i m trying to get that book to c how. thank u very much!

I have a question for any of the experts out there but first here is some code...
I wrote the following code in C# for reading absolutely any file type. It does work perfectly for any file type and the method or style is called a binary file reader....
byte[] buffer = new Byte[SizeBuff];
int bytesRead = 0;
int ByteCounter = 0;
inputStream = File.OpenRead(@InputFile.Text);
while ((bytesRead = inputStream.Read(buffer,0,SizeBuff)) > 0)
{
ByteCounter = ByteCounter + bytesRead;
}
int TotalBytes = ByteCounter;
byte[] ModifyThisFIle = new Byte[TotalBytes];
int KiloByteCounter = 0;
inputStream.Close();
inputStream = File.OpenRead(@InputFile.Text);
while ((bytesRead = inputStream.Read(buffer,0,SizeBuff)) > 0)
{
for (int a = 0; a < bytesRead; a++)
{
ModifyThisFIle[a + (KiloByteCounter * 1024)] = buffer[a];
}
KiloByteCounter = KiloByteCounter + 1;
}
NOT TXT file types and NOT the simple ifstream statements....
What is the simular or identical method for reading each character of a file IN VC++??? "What is included within and including the while loop statements to read" in VC++ for binary files like JPG, HLP, PDF, etc???
Thanks,

You could try the C api.
FILE *fSrc;
if ( (fSrc = fopen(".\\yourfile.bin", "rb")) == NULL)
assert(NULL);
int nLoop = yourGetFileSize(".\\yourfile.bin");
UCHAR *pBuffer = new UCHAR[nLoop +1];
int p = 0;
while (nLoop)
{
pBuffer[p] = (UCHAR)fgetc(fSrc);;
nLoop--;
p++;
}
fclose(fSrc);
delete [] pBuffer;
This will read byte by byte to the UCHAR buffer.
I am sure there are some STL based functions which could do the same.
