Database access is easy - MFC provides a number of options that do the grunt work for you. I'd suggest looking in the appropriate section of CP and ask questions if that does not help.
Good luck !!!

HI, I have added some menu items using CMenu::AppendMenu
and it all works nice. However, they miss the little help text that is displayed in the first pane in the status bar like when you create the menu items using the resource editor. Anyone knows a smart way to add help text string? Do I have to handle the message ON_UPDATE_COMMAND_UI for the ID_SEPARATOR which is the first pane in the statusbar? Or is there a better way?
Thanks, Patric

The fly by help is read from the string table. Make strings with the same resource ID as the corresponding menu items and it'll all automagically work.

Doesn't the mainframe have to be the parent of the menu for that to work?

Thanks, yes it was that simple, just add resource strings. The menu must have mainframe as its parent otherwise it didnt work. The same goes with UPDATE_COMMAND_UI, it is only handled if the mainframe is the menus parent

When I use CFileDialog in DCOM environment,But it can not work,Why?
For example:
Use MFC wizard generate a simple Dialog project,and add a button click handle;
add follow code segment,
void CTestOpenDlg::OnButton1()
{
// TODO: Add your control notification handler code here
CFileDialog dlg(TRUE);
dlg.DoModal();
}
compile,and run ,no problem!
1.
Now,Begin our test! add a code line to stdafx.h
#include <atlbase.h>
2.
and add _WIN32_DCOM to PreProcessor Definitions
(Project -> Settings set PreProcessor Definitions)
3.
add follow code.
BOOL CTestOpenApp::InitInstance()
{
HRESULT hRes = CoInitializeEx(NULL, COINIT_MULTITHREADED);
.......
...
}
int CTestOpenApp::ExitInstance()
{
CoUninitialize();
return CWinApp::ExitInstance();
}
4.
rebuild all project ,click button ,the CFileDialog can't diplay,and blocked in GetOpenFileName API.
Why? how to solve it?

|
|
|
1.
#include <<atlbase.h>>

Always initialize your main thread with AfxOleInit and it is not recommended at all to use CoInitializeEx(NULL, COINIT_MULTITHREADED) on your main GUI thread.
|
|
|
|
|
Thank you for your help.But use AfxOleInit instead CoInitializeEx(NULL, COINIT_MULTITHREADED) ,the program can not work ! some component CreateInstace fail .
Only can instead CoInitialize(Null).
please help me again!!

Is there a simple way of deciding when threads are better than not having them at all if optimisation is the goal?
Thanks all!

I have one rule, if the task may be long or asynchronous operation -> thread [yes]
if short task -> thread [no]

Hi,
I just wondered if anybody knew of any good example source code out there for file packers. I essentially just want to write a program that packs various files into one .dat (or whatever) file, which can then be unpacked and repacked on the fly.
Many thanks for any links/suggestions,
Keith

I have a class here that packs multiple files into a single file. And allows you to get back the files from the archive. No compression though. It's called CFileTar but is not to be confused with the Unix tar program or format.

Hey,
I need to programatically retrieve the exact file version number of RICHED20.DLL (such as "5.30.23.1205") and the control version (2, 2.1 or 3)
How can I do that?
I couldn't find the solution in MSDN Library.
Thanks in advance.

|
|
|
|
Have you tried loading the VERSIONINFO stuff from the DLL's resources?
Peace!

Hi!
I would like to insert a copy of a string table resource into a VC++ project like i've done with several dialog box resources. But i can't find the input text "Condition" in the resource properties.
Is it possible to make a copy of a string table resource with conditions?
Thks in advance!

Why does that prevent you from copying the string table itself, or entries within it? You should be able to cut-n-paste between string tables freely.
Peace!

Recently, I wrote on message board, that I had problem PostThreadMessage.
It did not post to the thread as expected, but GetLastError did not indicate that an error has occurred.
The bug disappear when I used:
Sleep(20);
to force it sleep for 20 ms. But when I tested it using larger test data, the same problem occurred, even more serious then before. Furthermore the performance eroded to point that it was better off not using threads.
In both cases, resources was critically reduced.
The "apparent" culprit was that the low resources. As the rate messages entering the message queue was higher than it's removal through processing, net increase in queue. Each message can contain significant amounts of data (up to 20k) and hence low resources. I have checked carefully there is no memory leakage so this was the only conclusion I could draw.
Closer study also showed that SendMessage also failed under these circumstances.
What I want to ask,
1, Has anyone else had this sort of problem?
2, Is my conclusion correct?
3, Is there a fix for this?
Thank you! Any reply is greatly appreciated
Kind regards,
wilche
The more simple things are, the more complex is the way it works.
The more complex things are, there is probably a simpler solution.

Does the thread in question has it's message queue created. That is does it call any of GetMessage, PeekMessage etc. functions before you call PostThreadMessage from other threads. That might be the problem.

Sorry my fault,
I have made sure that the message queue has been created properly.
This is because the messages inside the queue were correctly being processed.
Thanks for picking this up!

Hi,
this was a release build after the code had successfully compiled in debug mode .
nafxcw.lib(winctrl5.obj) : error LNK2005: "public: virtual struct CRuntimeClass * __thiscall CDateTimeCtrl::GetRuntimeClass(void)const " (?GetRuntimeClass@CDateTimeCtrl@@UBEPAUCRuntimeClass@@XZ) already defined in TreeOptionsCtrl.obj
nafxcw.lib(winctrl5.obj) : error LNK2005: "public: static struct CRuntimeClass const CDateTimeCtrl::classCDateTimeCtrl" (?classCDateTimeCtrl@CDateTimeCtrl@@2UCRuntimeClass@@B) already defined in TreeOptionsCtrl.obj
Do you have an idea what actually the problem is?
Thanks
R.

How does TreeOptionsControl.cpp look like. Does it by any chance has a definition of CDateTimeCtrl like IMPLEMENT_DYNAMIC(CDateTimeCtrl) or in any of the headers it includes?
|
|
|
|
|
TreeOptionsCtrl is from this site (PJ Naughter).
It has definitely IMPLEMENT_DYNAMIC(CDateTimeCtrl, CWnd) in TreeOptionsCtrl.cpp
|
|
|
|
|
...and compiles fine without.
Thanks very much
