My application is running very long loop and I would like to give the application time to redraw it-self and proccess all the messages and so on... I don't wanna use threads... For instance in that loop I am setting some text in CEdit and the application doesn't show it until the loop is finished... I really want something as simple as possible... Thanks for help to everybody....I really appreciate it.

Try putting in Message pumping looping into the code, maybe after completing a iteration in a loop. Adjust the below code for handling any accelerator or dialog boxes used.
if(GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}

This doesn't work for me, but thanks for trying...

You must either use multithreading or to implement a message pump (as Mayank Goyal suggested). As far as I know, there no other way to get what you want

I created a MFC application and opted for Help, but I have now included a Menu and want to place the Help option there.
The Help button on the dialog had no code behind it but when actioned it called up a Help file.
I just want the Menu item to call up this Help file. but cant find any code/options to change.
All I have done so far is move the
ON_COMMAND(ID_HELP, CWinApp::OnHelp)
in the App file into the dlg file, like this:-
ON_COMMAND(ID_HELP, CDialog::OnHelp)
What else do I need to do? I have created an event on the Menu-> Help item, but what goes in it.
Note the application has the Help files automatically generated.

Look at the WinHelp() function

All you really need to do is add a menu item with ID_HELP as its identifier. If I remember correctly, MFC will have some default handlers in place for this command which will automatically open the help file associated with your application.
If not take a look at the AppHelpX.cpp file which is part of MFC.
If you vote me down, my score will only get lower

I have created an ownerdraw listbox with the following Style.
pco_VerifyListBox->Create(LBS_HASSTRINGS|WS_CHILD|WS_BORDER|LBS_MULTIPLESEL
|LBS_EXTENDEDSEL|LBS_STANDARD,rect,GetParent(),GetDlgCtrlID()+ 4000);
it shows Error after the following line.
pco_VerifyListBox->SetVerifyList(pco_VerifyList);
SetverifyList Function has the following Defn..
----------------------------------------------------
void ct_VerifyListBox::SetVerifyList(
ct_VerifyList * pco_list)
{
assert(pco_list);
pco_VerifyList = pco_list;
ResetContent();
for (unsigned u = pco_VerifyList->FirstCond(); u; u = pco_VerifyList->NextCond(u))
{
AddString(pco_VerifyList->GetData(u).co_Item.GetCharPtr());
}
SetCurSel(0);
----------------------------------------------------
it gives Debug assertin in the AddString line..
It is from the MeasureItem funtion of the class CListBox.
also the program crashes...
what will be the solution for this problem?

Sorry Friends,,
There is a mistake in my posting..
the correct create statement in my code is
pco_VerifyListBox->Create(LBS_HASSTRINGS|WS_CHILD|WS_BORDER|LBS_OWNERDRAWVARIABLE
|WS_HSCROLL|WS_VSCROLL,rect,GetParent(),GetDlgCtrlID()+ 4000);
but the problem is the same...
pls tell me a solution.

Hi,
I need to connect to a DSN (data source name) via ODBC without writing the UID and password into my code in C++.
Has anybody an idea how to solve this issue?
Thanks.
|
|
|
|
|
What I'm about to say is doubtless obvious but... if you don't want to hardcode uid/pwd in your program, then you have no other solution than getting them from an external source (file, user input, registry, etc.)
|
|
|
|
|
Perhaps you could ask the user to input them at runtime.
Sorry already suggested.

It depends on the database you are connecting to. With SQL server, I use Windows Authentication and let Windows worry about keeping tracking of the username and password.
When Windows authentication isn't possible, I get the user to input the connection information in a config dialog and then encrypt it and store it for when it is needed.
Finally, if all else fails. I configure the DSN to already have the authentication setup, so all I have to worry about in my code is passing in a "DSN=<dsnname>" to my connection string.

Any tips on how to generate report using C++ programming (MFC). I have worked with visual basic before and is aware that VB has their own built in reporting tool for report generation. But im not sure how to do that using C++ language. Do I need to use Crystal Report? The report will contain info that is retrieved from the database. This report should also support the print feature. Pls help me! Tks...
Best Regards,

BusinessObjects provide an API for Crystal Reports. You should be able to find example C++ code on their website.

Best approach is using crystal report. You can use the Crystal report control just like in VB by adding the its OCX to your project. Crystal report object itself is capable of printing. You can pass query to your report in vc++.

Tks for your reply! I didnt work with Crystal Report in Visual Basic. I used their built in reporting tool instead. I would appreciate if u could provide me more details on "You can use the Crystal report control just like in VB by adding the its OCX to your project". Or do u happen to know of any good links that provide useful info?

OK. I could send you a sample application. Just send me you email or your MSN ID so that we could chat.
Using crystal report in vc++ is just like using any other registered control or active control if we would speak in vb. All you need is to add project reference to it, then drag the control to your dialog, assign a variable name to that control, then you can access the methods to display the report as simple as m_crystalreport.setaction() after initializing it.
To make it simple, here are the steps that i followed:
1. Install Crystal report
2. Create a dialog based application.
3. Click PROJECT->ADD TO PROJECT->COMPONENTS AND CONTORLS menu.
4. Locate under registered activex control the crystal report.
5. Click OK. Some info will prompt. Just click OK
6. Back to you resource viewer. A new icon will be listed in your Control Toolbar. If you hover your mouse pointer to it, it will have a tooltip indicating a crystal report...
7. Add that to your dialog.
8. Assign a variable name to it, using class wizard. Say you name it m_crystalCtrl;
9. Back to your class browser, crystal report interface classes will be added to your project. Dont bother about that.
10. add a button to your dialog, then add event hadler to it. say button _click event.
11. Assuming that you already created a report template( connected it with your db), then you can display the report by adding the following code:
m_crystalCtrl.SetReportFileName("MyReportFilename.rpt"); // change to you report filename
m_crystalCtrl.SetWindowMaxButton(TRUE);
m_crystalCtrl.SetWindowMinButton(TRUE);
m_crystalCtrl.SetProgressDialog(FALSE);
m_crystalCtrl.SetWindowShowProgressCtls(FALSE);
m_crystalCtrl.SetWindowState(2); //Maximized
m_crystalCtrl.SetDestination(0); //To Window = 0 Printer = 1.
m_crystalCtrl.SetAction(1);
m_crystalCtrl.Reset();

Hi all,
I need to create Korean font using MFC CreateFont() function Below i have given the code which i tried for creating the font.But the Korean characters are not getting displayed .Can some one help me in telling whats wrong with my code??

See this example on the GodeGuru forums. It shows you how to create Japanese text. The process is very similar for Korean text, but you use a different character set, a different face name, and different hex codes for the characters.
Follow the forum posts through one by one, and use the methods described there to discover the hex codes and stuff like that. Doctor Luz's post, where he shows an example code and the resulting character string, is a working example, as I tested them out myself as well.
Just use a different character set and a font. Also use Internet Explorer to determine what hex codes your text needs.

Hi...
forget abt this method to create font..
Use my method..
CFont *nFont = new CFont;
n_Font->CreatePointFont(200, "Batang");
CFont* pOldFont=(CFont *)pDC->SelectObject(&nFont);
pDC->TextOut(50,50,buffer);
pDC->SelectObject(&pOldFont);
I think it would work fine..also this font must be present in your system..
OK! Good bye..
