Thanks for the suggestion however I am still getting an exception on the CFileDialog.Domodal
Here is the the code from the main window when a user selects Debug Program the following
ON_COMMAND handler is invoked
Cprogdialog progdlg(this);
nRet = progdlg.DoModal();
return;
}
Then the follwing code is the on okay handler to this modal dialog box
void Cprogdialog::Process()
{
UpdateData(TRUE); CFileDialog dlg(TRUE, _T("asm"), _T("*.asm"), NULL);
dlg.m_ofn.lStructSize = sizeof(OPENFILENAME);
dlg.m_ofn.lpstrFilter = (LPCTSTR)"*.asm,*.cbl,*.c";
dlg.m_ofn.lpstrInitialDir = (LPCTSTR)"F:\\";
dlg.m_ofn.lpstrTitle = (LPCTSTR)"Program Source Code";
dlg.m_ofn.lpstrFile = new char[50];
dlg.SetParent(this);
if (dlg.DoModal() == IDOK)
AfxMessageBox((LPCTSTR)"Waiting for program " || (LPCTSTR)progname || (LPCTSTR)" In JobName " || (LPCTSTR)jobname,MB_OK);
The exception occurs at dlg.DoModal
Thanks again

There are many problems in your code.
The main problem that I see is the typecast to LPCTSTR.
I've said it before and I will say it again - Typecasting is evil.
Here is a sample code that you can use to correct your mistakes -
CFileDialog fOpenDlg(TRUE, L"txt", L"",
OFN_FILEMUSTEXIST|OFN_EXPLORER|OFN_HIDEREADONLY ,
L"All Image Files (*.jpg;*.jpeg;*.bmp;*.png)|*.jpg; *.jpeg; *.bmp ; *.png|Bitmap Files (*.bmp)|*.bmp|PNG Files (*.png)|*.png|JPEG Files (*.jpg;*.jpeg)|*.jpg; *.jpeg||", this);
fOpenDlg.DoModal();

You are using the _T() macro in some places to ensure your strings are correctly created as ASCII or Unicode. However, further down you are using the (LPCTSTR) cast. This means that your code should not even compile in Unicode mode. You also failed to tell us what the exception is that you are seeing.

Right after I try to step over the CFIleDialog.DOModal
a break is hit "int 3" the Call Stack points to somewhere in KerenelBase.dll
then doing a go PF5 results in a access exception
I red-did the code with L" instead of T("")
Thr CfileDailogBox I somewhat familar with its look appears not fully just the frame
right before "int 3" is hit
Thanks

So you think that randomly changing some strings to Unicode will fix the problem? My comment was made in the hope that you would actually think about what you are trying to do and whether your various parameters are correct. Read the documentation[^] and look more closely at the requirements for the different parameters on the CFIleDialog class.
You should also learn the difference between the _T() macro and the L prefix on strings. And finally you need to understand exactly what a cast, such as (LPCTSTR), does and how it affects the way your program runs.

So Process() is being called from OnOK()? Why are you wanting to browse for a file when the "main" dialog is being dismissed?
ForNow wrote: dlg.m_ofn.lpstrFile = new char[50];
I do not see how this is going to work.

Have you read the docs for this member? It must be double null terminated.

Okay i'll re-read the docs
I have a modal dialog box open to gather info
1 of the pieces of info is a file name so......
as soon as the user hits "OK"
I look for the last piece of info which a file thus the need to invoke CFileDiaog from the OKHANLDER of the first dialog box
you right I'll re-read the doc

When the user clicks the OK button, they are expecting to be done, not be presented with yet another dialog box. The OK button should not be available to click until all required information has been collected. It sounds like what you need is a Browse button to allow browsing for the file name.

I applogize
I have ON_COMMAND(IDC_PUSH,process)
In the message map
in the resource file I have DEFPUSHBUTTON IDC_PUSH
I haven't overriden CDialog::OnOk
I haven't defined a button with a ID of IDOK
maybe I should re-do the modal dialogbox as a modaal with DEFBUTTON of IDOK
since one the pieces of info i need is a file is omay in my OnOk overrride to invoke CFileDialog
to prompt the user for the file name?
Thanks

I would disable the OK button until all required information has been provided.

For what? What does Hans' article have to do with the title of this thread?

Instead of opening a second modal dialog box I'll add my controls to CFileDialog
|

Creating a proper main dialog with a "browse" button that opened a CFileDialog would be way simpler.

Hi,
I just got to work now but just before I left I re-built the code with only
CFileDialog dlg(TRUE);
one paramter as everybody was telling me I have problems wih my parms
as soon as I try stepping over dlg.Domodal();
I get a break point "int 3" some system DLL then entering PF5 "GO" again I get an access exception
I have a related question since I am creating the modal dialog box inside a modal dialog OKHANDLER what is the parent window the first modal or the MainWindow
Thanks

So why not take my advice, read the documentation, and fix the incorrect parameters? Unless and until you properly address the things that are obviously incorrect you are not going to make any progress finding the problem.

What about the OPENFILENAME structure?
ForNow wrote:

Does the Open dialog display, or is the exception thrown first?

The program takes the input of an initial key and an initial
vector, reads the plaintext or ciphertext from a file, conducts the encryption or
decryption, and writes the resulting ciphertext or plaintext into a second file.
test case is as follows: using a binary initialization vector of 10101010, a binary plaintext
of 00000001 00100011 encrypted with a binary key of 0111111101 should give a binary
ciphertext of 11110100 00001011. Decryption should work correspondingly.

When we are browsing for our library files which have extensions of .pal using CFileDialog we are also getting .palx displayed in the dialog.
This did not happen when we were using VC2003 but happened when we moved to VC2010.
Any ideas how to stop this behaviour as we generate the .palx files from our .pal libraries and we do not want users selecting the .palx

Check that your search filters are correct.

One of the constructors to the file dialog class permits you to specify a list of file extensions the dialog is permitted to show, check the documentation for more clarity, hope this helps.

Hi
We have implemented the functionality of "What's this" help button in our MFC code.
When select "What's this" help menu and press any control then help is displayed properly; but while click on the buttons of the toolbar, windows message
"Windows.hlp file is not found. Will you locate /specify the file by yourself" with Yes and No button appeared.
After some time message disappears automatically.
And We also do not found windows.hlp at our system.
We have facing this issue at windows 7 (KB917607 is applied) and at windows XP while trying to display the help message at same toolbar button help displayed successfully.
Thank You
