Try FindWindowEx() to find the main window, then use it again passing the main window as the parent, and it will go through the child windows one at a time. Maybe that'll be a start. I think the first time you have to pass a null as the parent window's handle and just specify the window caption.

<queue> queue threadsafe?

Hi,

I speak of the class std::queue / #include <queue>

In my case the question is:
1. Is it safe to execute m_queue.push from thread A,
while thread B executes m_queue.pop?
2. Is it safe to execute m_queue.push from thread A,
while thread B executes m_queue.empty?
3. Is it safe to execute m_queue.push from thread A and also from thread B?

I hope you understand what i mean,
thanks in advance

Snow.

None of the STL objects are thread safe. Wrap the calls in critical sections.

I'm going to patent thought. I have yet to see any prior art.

Thanks for your answer Tim.

I found an MSDN article "Thread Safety in the Standard C++ Library" which statet that some of the STL
container classes are threadsafe (but only in certain cases). But I think it will be better to write a wrapper for the queue class as you wrote before. It seems to be the only way to be on the safe side.

Thanks,
Snow.

Increasing of Header column of CList Control

I have on my form one Clist Control And One Button so that when I click on it, I see my data.

But my problem is this, every time I click on this button, the number of columns on my CList control is increasing. How can I avoid this problem

You probably keep inserting the column over and over again.
You need to completely clear out the control, or else set up the columns in OnInitDialog and don't keep adding the columns over again. You can add data items to the existing columns separately - when your button is pressed.

Add menu to dialog window

Dear ALL,

I would like to add a menu to my starting dialog window using WinAPI (I know how to do it with MFC). The code until now looks like I attached it at the end of the message.
But I dont know how to modify the "DialogBox(hInstance,MAKEINTRESOURCE
(IDD_MAIN), NULL, DlgProc);" - command to make it include my menu "IDR_MENU1" from the "resource.h"-file also.

Thanks for your comments.

Attach the Menu Directly to the Dialog Box.. you will option of that on right clicking on the dialog box resource

1. when windows sends WM_QUERYENDSESSION message to the applicaitons at logoff, does it send it to all at once or send it to the applications one by one?
2. does it send it to the apps in any specific order or is it undefined?
3.

thanks!

This link says:
Every FAT32 partition has its own RECYCLED folder in the root while every NTFS
partition uses a RECYCLER folder in the root. NTFS also creates one sub-folder for
each user (e.g., C:\RECYCLER\S-1-5-21-1644491937-1078081533-725353535-1003).

1. For NTFS, the folder name is the SSP key. For restricted key this registry key under HKEY_CURRENT_USER\Software\Microsoft\Protected Storage System Provider is not readable, is there any other way to find this out?

2. For FAT32 partitions, any idea how the sub-folders are named?

thanks!

Mem dc from nothing

mintguy22-Nov-05 23:58

Is it prossible to create a MemDC without a screen or printer DC to base it on.

I have an MFC program that I want to be executed by a web service. The program writes to a DC and then saves the bitmap.

If I run this program from a web service, presumably there is no window to base the DC for the bitmap to draw on. so I jsut want to create a Mem DC to draw on.

If I want to draw on say a 1024x1024 bitmap with a bit depth of of 32 bits.

How can I do this?

Use the desktop DC. I have a graphing library running as a web service doing exactly what you describe and it works great.

Snippet of code that sets up the DC:

CRect oBmpSize(0,0,lWidth,lHeight);

oMemDC.CreateCompatibleDC(NULL);
int iOldMapMode = oMemDC.SetMapMode(MM_TEXT);

CWindowDC dcScreen(NULL);

oBmp.CreateCompatibleBitmap(&dcScreen,oBmpSize.Width(), oBmpSize.Height());

pOldBmp = oMemDC.SelectObject(&oBmp);

onwards and upwards...

I think you should be able to use SetRedraw() turning it off while sizing, then turning it back on when finished.

Hi Anybody has a VC++ sample code for an ActiveX control to be viewed via IE browser that is capable of downloading a file (say via winsock or http api) from the website where it is hosted?
thanx in advance

hi

you can build ActiveX control with MFC ActiveX control wizard.so it is not a big deal.

main thing is to show it in browser.

for that you have to sign your activeX control.other wise it wont be shown due to default security settings of the browser wont let it(unsigned ActiveX control) execute.

to sign your control for testing purpose you can use codesigning SDK.
