All that has happened is that the WaitForSingleObject has timed out. You are only waiting 250 milliseconds for the mutex to be signalled. Sometimes this may not be long enough.
You can check for WAIT_TIMEOUT from waitReturn in the same way you are checking WAIT_OBJECT_0.

hi,
suppose that name of exe is "XYZ.exe"..Then how can I get the path of the exe using ur Method.?
Thanks in advance

the other method works only within a running program.
for you, use CFileFind or FindFirstFile and FindNextFile

Sorry, I misunderstood you. If you have a name of an arbitrary .exe file and you have no idea where it is located, then the only way is (AFAIK) to scan the disk. You could use the MFC class CFileFind to find a file with a given name - you would have to supply in what folder to look, and you would have to recursively walk through all folders. Not a trivial task I believe...
If however the .exe in question is the .exe you are writing then you can use the code I showed you.
What exactly is your requirement, i.e. under what circumstances do you need to do this?

Hello,
is there anybody to explain me how to disable an item from a menu ?
One of my items are for exemple ID__STOP :
in my .h file:
afx_msg void OnChoixMenuStop();
afx_msg void OnUpdateMenuStop(CCmdUI *pCmdUI);
and in my .cpp file :
BEGIN_MESSAGE_MAP(CAppDlg, CDialog)
ON_COMMAND(ID__STOP, OnChoixMenuStop)
ON_UPDATE_COMMAND_UI(ID__STOP, OnUpdateMenuStop)
END_MESSAGE_MAP()
void CAppDlg::OnContextMenu(CWnd* pWnd, CPoint point)
{
CMenu menu;
menu.LoadMenu(IDR_POPUPMENU);
menu.GetSubMenu(0)->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON,point.x, point.y, this);
}
void CAppDlg::OnUpdateMenuStop(CCmdUI *pCmdUI)
{
pCmdUI->Enable(FALSE);
}
I would like to get it grayed or disabled but i can't...
Please if you can help me it would be great !

Your menu is created every time the OnContextMenu method is called, so you have to disable the button in OnContextMenu (using the EnableMenuItem method of CMenu before TrackPopupMenu) or in the resource file of your project.

Hello,
thank you for your answer, but the fact is that I want to modify the state of my items from OnUpdateMenuStop(CCmdUI *pCmdUI) and not from OnContextMenu(CWnd* pWnd, CPoint point).
I've just found the answer in the knowledge base of microsoft Q242577. My application is dialog based (CDialog) and this is the bad point... But the give in Q242577 the 'OnInitPopupMenu' which solve the problem !!!
I wish you a nice day,

Ok. Here is a problem.
I try to find current resolution using EnumDisplaySettings function. Everything is ok, but when I run this function while playing game , it gives me old resolution used for desktop. For example. My desktop resolution is 1024x768x32. I start Zuma Deluxe, which switch resolution to 640x480x32. I wrote a small program which uses timer and every 2 seconds check current resolution and put it in memo control. Ok. I run program and see resolution is my desktop resolution. Now I run game (test program still active), playing for example 1 minute and then exit from game. Looking in memo control in my test program, no 640x480 in the list! Whole list containt 1024x768! Hmm, strange. So I assume that EnumDisplaySettings with ENUM_CURRENT_SETTINGS only show me resolution which was used as permanent (I this with CDS_UPDATEREGISTRY in ChangeDisplaySettingsEx function). But games change resolution temporarily! So how I can find current resolution regardless of mode of this resolution?

The problem you have encountered is that DirectX games do not go through the GDI in order to increase their speed.
When you use a call to the GDI function EnumDisplaySettings you get the current GDI settings and not the DirectX settings.

It doesnt work even for OpenGL applications.
So how I can find resolution? 
|
|
|
|

No, OpenGL works in the same way as DirectX. They both have drivers that write directly to the video, bypassing the slow GDI.
Sorry I do not know how you could detect the resolution for either DirectX or OpenGL outside of the particular application itself.

Thats bad. I'm trying to create ScreenShot Maker and all I need is detect current resolution
Hmm, it seems that I have to do in on the hardware level .

I'm trying to run "Triangle" in Microsoft Visual C++. I define the NO_TIMER as its not a Linux system. It compiles and runs, giving a list of the commands I can use. Hitting any key just closes it down, with nothing else happening. How do I get it to create the proper file?
I ideally would like a C++ version of Triangle, so I can incorporate it in an existing project. Any links to information about this would be appreciated.

Hi
I have a dll that will be used simultaneously be different processes. The dll opens a database connection that is to shared among all the processes that used this dll. This is to avoid opening the database each time by each processes whenever they need something from the database.
I believe this can be done by sharing the virtual memory using VirtualAllocEx, WriteProcessMemory, ReadProcessMemory apis, is that correct ?
If so is this the correct approach ?
If not what is the best approach ?
Thanks in advance

Hi there,
I have tried to get a dialog to transfer data from a combobox into the view class member but I havent been able to get it to work get crashes.
All I want is a tutorial on how to change som variables in a dialog that effects the members of the view class. This must be a ordinary thing that must want to achive. Every windows program has dialogs to set alot of options etc.
Hope you got something for me!.)
regards
Peter

Hi
I understand your problem is to accept user input through a dialog and get those data in the View class of a SDI/MDI, is that so ?
Then you could try doing this,
Insert a Dialog into the project.
Add the control you want on the dialog.
Now add a class CUserDlg for the dialog, deriving it from CDailog.
Add member functions like GetName, GetAge, GetGender etc to the CUserDlg, these should return the data that you want to pass to the view class.
Now create a memberf m_dlgUserData of type CUserDlg in the View Class.
Call DoModal to display the Dialog and when finished (ie pressed ok)
Call m_dlgUserData.GetAge(), to get the age of the user. This way you get the age of the user entered in the dialog into the View Class.
Hope I answered your question...

The simplest way of transfering data between dialogs and views. Is to pass a pointer to the view class into the dialog class either via the constructor or via a method that is called before DoModal.
In the constructor, assign the view pointer to a class member variable and then you can call view methods in any of your dialog methods.
