how to get the list of software programs installed using c?
|
|
|
|
|
The details of all installed applications are stored in registry under,
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
Since you have a preference for C Compiler, You can use plain windows api to read the registry and populate the list. This article[^] will be helpful.

Googling[^] would lead you to an article[^] on a useful programming related site called CodeProject.com - you may have heard of it.

you can right click on the dialog and select Insert ActiveX Control and select the windows media player activex.
once its selected then create a member variable for it. you get all the wrapper classes that is required for the activex component to work properly.

The link I gave was related to Embedded Development... So I am not sure about usefulness...

I just tried it...
I inserted the activex and created a control variable of class CWMPPlayer4. And called the the m_obj.SetUrl( "filepath" ). I could play an mp3 file.
But I am not sure about a good reference. But I found that googling the string "CWMPPlayer4" would guide you better.

I am working on a project intended to control the print flow on the network. User will not be allowed to print on the printer directly. In any case EMF spool file will be generated and parsed and then forwarded to the actual printer(any PS/PCL) printer.
For forwarding the print job , I am just taking the destination printer device context and playing the spool file on the destination printer using PlayEnhMetaFile function, so it is printing on paper. Every thing works fine up to this level.
But I am getting some problem. The output from print job forwarding and the direct printing to the printer is somewhat differ.
I want to get same out put from print job forwarding as I am getting direct printing.
For that reason I am counting RECT to play enhanced meta file on the destination printer using following formula.
float PixelsX, PixelsY, MMX, MMY;
RECT rect;
PixelsX = (float)GetDeviceCaps( dc ,HORZRES );
PixelsY = (float)GetDeviceCaps( dc, VERTRES );
MMX = (float)GetDeviceCaps( dc, HORZSIZE );
MMY = (float)GetDeviceCaps( dc, VERTSIZE );
rect.top = (int)((float)(pEMRHeader->rclFrame.top) * PixelsY / (MMY*100.0f));
rect.left = (int)((float)(pEMRHeader->rclFrame.left) * PixelsX / (MMX*100.0f));
rect.right = (int)((float)(pEMRHeader->rclFrame.right) * PixelsX / (MMX*100.0f));
rect.bottom = (int)((float)(pEMRHeader->rclFrame.bottom) * PixelsY / (MMY*100.0f));
Here "dc is Device context for the destination printer" .
But each time I am getting somewhat big print from the printer.
Is it right way to calculate the RECT?
It would be help me if you can look into the problem please.
Thank you.

MAhendra

The easiest way to do something like this is to take a slightly different approach:
- Use Windows 'Print to file' to produce a file containing the printer driver's output
- Copy the file to the 'printer port'. This can be a networked printer.
For example, on the LAN I'm using, there's a printer called 'mint' that's served through a print server called 'greenhouse'. If I print to a file, 'd:\test.prn', the following will cause the file to be correctly printed:
copy d:\test.prn \\greenhouse\mint

I have 3 values "number name and value" for different parameters in a notepad..
My Question:
Suppose a notepad say A contains the above values in the following manner
number1
name1
value1
number2
name2
value2
.
.
.
.....and so on till say 500 parameters..Now I have a notepad B which is empty.I am using a listbox which contains the list of all parameter names.So if I click on a particular name,it must automatically take the corresponding number and value of that parameter name from the notepad A and store them along with the parameter name selected in notepad B.The listbox is a multiselection listbox.I want to execute this using VC++ MFC classes.Can anyone pls help me how to do this?
Thanks,

notepad to me means notepad.exe, a simple text editor.
I assume you mean a text file?
So you many small problems you can work on one by one.
1/ How do I read a file,
2/ I need to take 3 lines at a time, and fill a structure with: Number,Name and Value. I don't know if value is text, floating point or integer
3/ Make an array or list of these structures as they come in
4/ Have a list box, and populate it with this information - I'd suggest a ListCtrl in report view; but if you could do that, you'd be asking different questions. Keep it simple first!
5/ Detect a click on the list box
6/ Write the contents of the correct array entry to a file.
You problem sounds intimidating at first - so don't swallow it whole, try bite sized nibbles.
Each of the above stages should be solvable with your favourite book / msdn.

i have created a simple project in Visual studio 2008 after installing the feature pack.
i found that there are new classes for toolbar, menu etc viz: CMFCToolbar, CMFCMenuBar, ...
now if i want to use the old class CToolBar and create a toolbar, then DockControlBar() function fails.
is there no way to use CToolBar class?
sample code:
after i create the toolbar, i dock as follows
m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);
EnableDocking(CBRS_ALIGN_ANY);
DockControlBar(&m_wndToolBar);
thanks
