I think I could not describe my problem, I want to know how to change the Mouse pointer shape in console application but SetConsoleCursorInfo change
the cursor shape which indicate text postion for next typing character.
In second reply getconsolewindow is not working I check its documentation but there is no header file specfied for it, and one thing more whcih u ask LoadCursor(NULL,IDC_HELP) returning a value other than NULL so its mean it is a valid cursor.

（1）In MDI sub-window, how can I intercept the activated news, and neglect it??
（2）In MDI windows,I want to set a sub-window as desktop in MDI windows(be placed under the other windows). now I rewrite the news handles method, if it processes to 0x086,it does not process any, and the result is making all windows' activate status abnormal, the title bar is not brighter, the menu also can't merge with the main window.
One is never too old to learn

Could you be a bit more specific ? What is the thing you are trying to accomplish ? I know this question sounds silly, but I, at least, have no clue about your goals.
For example:
1. News ? What news ? Are we talking about a MDI child window ? What is it that you want to intercept ? A Windows message ?
2. A sub-window as desktop in MDI windows... Eh ? Are you talking about the MDI application mainframe window (toolbars, menus), or about the Desktop(tm) window (Windows Desktop), or something else ? What is this '0x086' you are talking about ?
If you clarify these issues and perhaps post some code along, we might be able to help you much better

I have programmed with Win32 enough to be called an advanced user I guess, and now I wish to port my app to handhelds...what I am looking for the analogous book: Programming Windows 5th Edition by Charles Petzold for PDA's...anything that good out there?
|

I want to obtain, preferably via WMI, a list of all the installed applications on a given box. WMI has the classes win32_Product, win32_SoftwareFeature, and win32_SoftwareElement for this purpose but they ONLY cover apps installed via MSI. I waded thru lots of classes but have yet to find any in WMI that will give the complete set.
Question:
a) Does any one know of 1 or more WMI classes that will yield the complete set of installed apps, whether or not installed via MSI.
b) If not, does any one know an alternate method?
Thanks.

They only list MSI packages because the MSI runtime (msiexec) keeps a database of installed products. The WMI provider simply queries this database.
Other setups all work differently. InstallShield (not their MSI package, which goes for everything else mentioned forthwith unless otherwise stated) works differenly from Wise and does seem to keep an internal database of components, those it doesn't seem to happen for packages (speaking in MSI terms here). An up-and-coming install by Nullsoft (makers of Winamp) is very basic and doesn't seem to do anything but keep a log of what was done so it can be uninstalled (sort of like a DB transaction).
The only thing these installation methods have in common is that they almost always (some Windows Update components don't because you can't uninstall them) write to the registry key HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall. You could browse through there and see what registry keys are useful and pretty consistent, like the DisplayName and UninstallString.
As far as querying these, there is - I believe - a WMI provider for the registry. It's been a while since I've played with WMI so I apoligize. If nothing else, registries can be queried remotely by someone with the appropriate permissions, which WMI (or the responsible provider) will most likely enforce anyway.

Heath,
Thanks a bunch - I figured "the registry" was going to be the answer, but wasn't sure exactly which keys would get me there - the key you pointed out looks very promising.
But I was actually hoping that WMI provided a direct abstraction for this in some class I had so far missed. You know, a direct equivalent for the above mentioned classes (product, swfeature, swelement), but only that they included everything, not just MSI installed apps. Oh well...
In any event, you are correct - there is a provider for the registry, so I can get at the key you mention using it. Looks like that is the best route.
Thanks again!
Jerry

That registry key IS the place that installers MUST write to if they want to appear in the Add/Remove Applications control panel applet and participate in the functionality provided for installing and uninstall applications.
There isn't an abstract way of doing this, though. Like I said, every installer uses a proprietary installation routine. When you think about it. MSI is database-driven and as a result uses databases to store package, feature, and component information. Other installers are pretty much script-based, but I can't say ALL because even using a batch file to perform an XCOPY is considered an installation routine. The point is that they're all proprietary so there's no abstract way of getting information.
The registry is the one ring that binds them together (sorry, eagerly awaiting LOTR-ROTK!).

How to get information from a screen into file?

Can you be a bit more specific? If you are simply wanting a snapshot of the screen saved to a BMP file, see here and here for ideas.

Hi ,
Can u pls help me out with code in VC++.
I am using DirectShow filters to compress the audio I capture from Microphone.
The filter flow is as follows WaveDest->Encoder filter(Using GSM 6.10)-> Sample Grabber.
With the Sample Grabber filter I have grabbed some samples and written them into a bts file. So now I have the GSM compressed audio file in my "buff.bts" file in the form of bitstream.
Now how do I get the original file I captured from the mike to be rendered through the speaker. i.e In order to decode this Bitstream do I have to use decode filter in the playback graph but I do not know how to get the GSM 6.10 decoder filter.
Pls help me with the code

HI ,

Cannot load the DLL sim.dll, or one of the DLLs it references. Reason: 126(The specified module could not be found.).
can any body help me

It seems that some dependency dll is missing - check your dll with dependency walker and you'll see what are the dlls it need.
Probably it's some msvcrt or something like that.
Hope it helps

Hi there,
i hope that someone can help me with this.
My application is SDI.
I wroted a class derived from CListCtrl which is created with
LVS_OWNERDRAWFIXED style.
There is a strange behaviour when i click on a different subitem on the same
selected row. It seems that it takes 800 ms till DrawItem is called.
My class implements two methods:
void OnLButtonDown(...)
{
TRACE("Start OnLButtonDown...\n");
...
CListCtrl::OnLButtonDown(nFlags, point);
TRACE("End OnLButtonDown...\n");
}
void DrawItem(...)
{
TRACE("DrawItem...\n");
...
}
When i click at different rows i see in the debug window:
Start OnLButtonDown
DrawItem
DrawItem
..
..
End OnLButtonDown
Meaning, DrawItem is called before OnLButtonDown() finishes.
However, if i click on the same row again i see in the debug window:
Start OnLButtonDown
End OnLButtonDown
DrawItem
In that case, DrawItem is called 800 ms after OnLButtonDown finishes.
Any idea?

Its probably due to the difference between a selection change and no change.
When you click the item for the 1st time, the control sends a message to the windows owner using SendMessage(). This causes the message loop to pump and process all the messages in the queue (otherwise the thread would block) which causes any WM_DRAWITEMs in the queue to be processed. When clicking the item the second time, the selection changing messages are not sent, as there has been no selection change, so the queue is not pumped until it returns from the LButton handler.

Hi Roger,
thanks for your reply.
You explanation seems very reasonable.
How would you solve that delay?
I tried to force sending selection change by calling SetSelectionMark method in OnLButtonDown,but the delay stays still.
I even called Update method or RedrawItems but the result is the same.
What cause the sole WM_DRAWITEM event to be sent after LButton handler returns?
How to solve the delay?

|

I think you would need to call:
RedrawItems(index, index);
UpdateWindow();
To move up the WM_DRAWITEM calls.

And if it is a CFormView you need to create a new document, like this.
POSITION templatePos = GetFirstDocTemplatePosition();
while(templatePos != NULL)
{
CDocTemplate* pTemplate = GetNextDocTemplate(templatePos);
CString strDocName;
pTemplate->GetDocString(strDocName, CDocTemplate::docName);
if(strDocName == "Form you want to open")
pTemplate->OpenDocumentFile(NULL);
}
