Just a hunch, but:
I think it may have something to do with the fact that immediately preceding the "/stuff.html" is a path element called "program.exe".
The fact that there is a dot after "program" may be confusing the parser to think that everything after the dot is the file type.
What do you think?

I'm not sure. According to MSDN and other docs I found, that is supposed to be the format, i.e.
res://fully-qualified-exe-filename/resource-name

You're probably right. 
It was just a first thought.

no prob. Interestingly enough I just tried this with an older version of IE and it works perfectly, so it's definitely an issue with IE7, some subsequent patch to IE7, and/or some related windows component. Joy.

I looked into the htm file I once used for an HTML Dialog box in MFC.
It uses a resource graphic, and it specifies the graphic name as:
src="res://Program.exe/#2/#133"
If I recall correctly, the #2 indicates the resource TYPE, such as bitmap, and the #133 represents the exact resource identifier.
Try that type of res URL, and see if it works.
You'll have to determine the correct number for the resource type of HTML.

res Protocol
--------------------------------------------------------------------------------
Specifies a resource that will be obtained from a module.
Syntax
res://sFile[/sType]/sID
Tokens
sFile
Path and file name of the module that contains the resource.
sType
Optional. String or numerical resource type. This can be either a custom resource or one of the RT_ predefined resource types described in the FindResource function reference. If a numerical resource type is specified, the actual number of the identifier, not the identifier name, must follow a # character. See the example for more information. If this parameter is not specified, the default resource type is RT_HTML.
sID
String or numerical identifier of the resource. If a numerical identifier is specified, the actual number of the identifier, not the identifier itself, must follow a # character. See the example for more information.
Remarks
Available as of Microsoft Internet Explorer 4.0 or later.
Remember, URLs require that special characters such as '#' be escaped. Use '%23' to escape the '#' character.
Note Internet Explorer 6 Service Pack 1 (SP1) no longer allows browsing a local machine from the Internet zone. For instance, if an Internet site contains a link to a local file, Internet Explorer 6 SP1 displays a blank page when a user clicks on the link. Previous versions of Internet Explorer followed the link to the local file.
Example
This example shows the correct and incorrect ways to format the numerical identifier for the resource type.
#define MYBITMAP 234
// This is correct.
"res://mydll.dll/#2/#234"
// This is not correct.
"res://mydll.dll/#2/MYBITMAP"

Hi all.
I am trying to create a simple magnifier application which follows the mouse and magnifies the portion around the mouse cursor. I know how to get a screenshot of a desktop. I have tried GDI way and DirectX9 Surface way, but DX surface is too slow for realtime capturing. So I am staying with GDI.
The problem is - when I get a screenshot my magnifier application is included, too. I tried to GetNextWindow and GetFocus to get HDC only for the active window and then render HDC into memory DC. But it is a nightmare - some applications have multiple windows so I get only one of them and the other part of the shot is a mess (from previous shots). I guess it would be really hard to get DC for every window beneath my own and to combine all the DC images myself. Brrr...
One approach could be to hide my app, capture screen, restore my app. But it is not suitable for realtime work.
Of course, I know that Windows keeps track of window clipping regions so area behind my window would not be updated in other windows WM_PAINT. But I think I can force it to render if I use WS_EX_LAYERED style and 99% visibility for my app - then Windows invalidates area even behind my window. Of course, I can remove CAPTUREBLT flag from BitBlt when capturing and then I won't get my window because all layered windows would be ignored. But then I do not get any of the layered windows (like tooltips etc.).
I know that Vista Magnification API can do the trick but it does not work on XP 
So the problem is - how can I virtually "erase" my app from the screenshot and get area behind it?
Thanks for any ideas.

HRESULT hr = OleGetClipboard(&pDO);
FORMATETC fmt = {CF_HDROP, NULL, DVASPECT_CONTENT, -1, TYMED_HGLOBAL};
STGMEDIUM stgm;
hr = pDO->GetData(&fmt, &stgm);
if(S_OK == hr)
{
UINT nFiles = DragQueryFile((HDROP)stgm.hGlobal, -1, NULL, 0);
int i = 0;
for( i = 0; i < nFiles; i++)
{
ij=1;
DragQueryFile((HDROP)stgm.hGlobal, i, szPath12, MAX_PATH);
szPath12;
}

You are trying to link with two different versions of the C runtime library (MSVCRT). This usually occurs because you are linking with object code or a static library that was compiled against a different variant of the CRT.
Make sure that all of your code uses the same run-time library option (it's in the C/C++ compiler properties, in the Code Generation page).
|
|
|
|

It seems that you are using STL. The possibility is that the variable you are using in the AtlABFUtil.cpp is already been defined in abflib.cpp. Have you included abflib.cpp into atlABFUtil.cpp ? Can you post code snippet for more details ?

When trying to create CMDIChildWnd in a worker thread I get an ASSERT fails in winmdi.cpp:
if (pParentWnd == NULL)
{
CWinThread *pThread = AfxGetThread();
ASSERT(pThread);
CWnd* pMainWnd = pThread->m_pMainWnd;
ASSERT(pMainWnd != NULL);
ASSERT_KINDOF(CMDIFrameWnd, pMainWnd);//****this line fails
pParentWnd = (CMDIFrameWnd*)pMainWnd;
}
S I guess the parent window is not being set correctly. How can this be set?

You *have* to create the child window in the same thread its parent was created on. My usual rule is to keep *all* windowing operations within one thread. If you need to create a window in response to an event in a worker thread, post a message across from the worker thread to the main UI thread (posting messages is allowed from worker threads to the UI thread).

Is there any sourc framework code that i can use ? just like Syncfusion Essential Studio(SES), but "SES" is .net based, the startup time is too long for my customers, so i need to find a mfc based source library.
CAD method is not prefer for my customers, they like visio method.
thank you for you help

Hi,
I use .NET almost all the time, and almost all my apps start up in less than 1 second.
If it takes longer, something inside the app is probably wrong.
Also, very complex apps may take longer, whatever the technology; MS Word is not .NET based!
|
|
|
|
|
I do a test of build a winform and a mfc dialog app, which only contain a visio11 activex control. The startup time is very different, .net winform app sometimes costs about 10 second, but mfc dialog only cost 2~3 second. I have no ideal of accelerating the startup time of the .net winform app.
|
|
|
|
|
and the startup time i said refer to the "cold" start, that's to say, after i restart the computer, the first time i run the .net based app

I am writing any application using C++ and MFC. Please consider the following two class member functions:
<br />
void ReportASuccess()<br />
{<br />
successCount ++;<br />
this->Invalidate();<br />
}<br />
<br />
void ReportAFailure()<br />
{<br />
failCount ++;<br />
this->Invalidate();<br />
}<br />
There two functions will be called many thousands of times by several worker threads to report results. I am concerned that the increment of the counters successCount and failCount is not thread safe. That is, if the thread loses focus in the middle of the increment, there could be a problem. Do I need to worry about this, and if so, what is the way around it?
By the way, the two member functions shown above are part of class that handles the GUI.
Thanks
Bob

Hi,
if this is a GUI part, i.e. some Control (maybe a Form), then those functions
have to be executed by the main thread aka GUI thread, hence successCount and failCount
are single-threaded variables; the GUI thread cannot preempt itself.
If your worker threads are to call these methods, you need a mechanism to defer the execution
to the GUI thread, something similar to Control.Invoke in .NET
FYI: the general solution for thread-safety involves synchronization of some kind, here
locks could be appropriate; you are aware of the _Interlocked functions, such as _InterlockedIncrement, are you?
|
|
|
|

For example, create a mutex using CreateMutex[^] and use WaitForSingleObject[^] to wait for access, something like this:
void ReportASuccess()
{
if (WaitForSingleObject(handle_to_your_mutex, INFINITE) == WAIT_OBJECT_0)
{
successCount ++;
this->Invalidate();
ReleaseMutex(handle_to_your_mutex);
}
}
void ReportAFailure()
{
if (WaitForSingleObject(handle_to_your_mutex, INFINITE) == WAIT_OBJECT_0)
{
failCount ++;
this->Invalidate();
ReleaseMutex(handle_to_your_mutex);
}
}
If your Invalidate() method belongs between WaitFor... and Release depends on what it does. Generally, i think, a thread will not loose control over the CPU in the middle of an increment/decrement operation, however, this might change with a multicore or multiprocessor system.
As an alternate solution, if your ReportASuccess and ReportAFailure methods are used to control the GUI thread, you could use PostMessage[^](or rather PostThreadMessage[^]) to signal events (just try not to flood your GUI thread with messages).
On a sidenote, be careful with updating the GUI from a different thread than it was created in because this might -and probably will- lead to failures and deadlocks.

Thanks for the response. I am leaning towards using the PostMessage approach. I am wondering why you said PostMessage rather than SendMessage. Is one better than the other?
I am also thinking that if I wanted to use the locking approach, that I should use two locks. That is, when one thread is reporting success, the other thread can report failure. Maybe I did not give you enough information. Each thread represents a simulation of a stochastic process. Some times, due to luck, they will report success. Other times, they will report failure. What user cares about is the percentage of time they report success. Right now, it is taking about 10 milliseconds per simulation and when the program is put into use, the user will be doing about 1 million simulations per run.
With that said, if I use the locking approach, is there any reason to use only one lock?
Thanks
Bob

If you use SendMessage you are actually calling the message handler directly from the same thread you called SendMessage in, while if you use PostMessage, you are placing the message in the other thread's message queue and it will handle the message when it gets to it in its own thread. So basicly, if you use SendMessage, the message handler will run in the same thread that called SendMessage, if you call PostMessage, the message handler will run in the GUI thread (or at least the thread that owns the message queue).
For the locking aproach, you can use 2 different locks, there was no special reason why i used the same mutex, and using 2 different locks is probably better for performance, i was just lazy...sorry.
It really mostly depends on what resources the two methods access, since you are increasing two different variables you don't need to have the same lock for both, but if they use the same Invalidate method which might access resources which should not be accessed by multiple threads at the same time you would need to use the same lock. Depends on the situation and structure.
