In addition to the other answers here, I think you should start with getting the Windows DDK. You will need it.

Hi guys,
I have a problem.
I would like to make the system menu the menu of my notify icon. The menu comes up but doesn't work. I am doing so that the user can work with the application even if it is hidden and I don't want to create another menu.;)
Is it possible to do this.
Thanks

AFAIK, you have manually route them using your custom Window Message Handller which you have mentioned while creating the System Tray Icon i.e. NOTIFYICONDATA.uCallbackMessage

Yeah that is fine.
It is working like that.
But I wanted the system menu to be displayed as the tray icon menu. The menu is coming but not working. So I wanted to whether there is another way of going about this apart from using another menu.

I use Windows XP.
I created a new desktop named desktop2, switched to it using SwitchDesktop API and created a explorer process there using CreateProcess API.
Everything is fine, but the windows shortcut key is not working in the new desktop. If I use Win+E to get the explorer, explorer opens in the default desktop, not in the new one.
What can I do to get rid of this problem?
Thank you.

I have a class that takes this list of name value pairs:
<mydocs> - C:\docs and sets\user\my documents
<home> - C:\docs and sets\user
and then there is a function, that substitutes these variables in "<home>\\local settings".
but I dont know what to name this class. any suggestions?
thanks!

SQLOLEDB.1 is plainly not a Prog ID for a data source you have available to you on this machine, or it has a password that you've not provided. I have SQL Server installed, and SQLOLEDB.1 does not exist in my registry ( I didn't expect it to ). Where did this code come from ? Did it ever work ? I reckon it's been copied and pasted from the web. If this is what your senior programmer does ( copy/paste/give it to someone to make it work ), I'd be looking for a job.

It looks like a mess to me, this is written by the senior programmer you say ?

Truely speaking this entire function in his code working very properly when i am trying to implement it is refusing to connect.
In our firm there is only one database.One thing is sure he has used some OleDB concept ,second thing you can find word SQLOLEDB

That's lovely. Obviously, his computer is configured to use it and yours is not. So why don't you ask him ?
shivditya wrote: second thing you can find word SQLOLEDB

I'm sure you can, but if it relates to a prog ID that gets set up by SQL Server automatically, it would be set up on my computer. MSDN said to pass in a prog ID, which would be in the registry if it was set up.
Instead of asking the same question over and over, and not following up on the advice people give you, go and ask the guy who wrote the code, because it's obvious the issue is one of setting up the database connection on your machine.

Why don't you try to open the database connection in a database gui tool, and see what happens?
You might get interesting information about the problem that way.
Just a thought...

I am trying to work with icons in the system tray and on the title bar and the resource editor from the 6.0 suite. I can only create bitmaps or icons with 256 colors. Is there any way that I could create an SVG file or PNG/JPG and use those for the icons?
|

Now, I have VS .NET 2002 so I'm not sure this works for you. I recently started working with CTreeCtrl's and I needed two custom icons. I created them in MS Paint, saved as 16x16 24-bit bitmaps. I imported them into my project via the resource view, they showed up under the category "Bitmaps", one called IDB_FILE and another called IDB_FOLDER. For the CTreeCtrl, to use icons, I have to load up a CImageList data type with my images, then attach it to the CTreeCtrl. This is the resulting code in regards to the CImageList, I don't know how helpful it was but it did the job fine for me:
m_images.Create(16, 16, ILC_COLOR24 | ILC_MASK, 0, 2);<br />
<br />
CBitmap folder;<br />
ASSERT(folder.LoadBitmap(IDB_FOLDER));<br />
ASSERT(m_images.Add(&folder, RGB(0, 255, 128)) != -1);<br />
<br />
CBitmap file;<br />
ASSERT(file.LoadBitmap(IDB_FILE));<br />
ASSERT(m_images.Add(&file, RGB(0, 255, 128)) != -1);<br />
<br />
m_tree.SetImageList(&m_images, TVSIL_NORMAL);
Note, m_images is the CImageList and m_tree is the CTreeCtrl.
I also implemented a mask so the background of the control can be changed and the icons' picture will change appropriately. I painted the RGB color 0, 255, 128 on the image where I want transparency then on the Add() command, I specify what color the mask color is. Again, I don't know how helpful this is to your project but good luck.

Thank you for the response. Unfortunately though, when I import anything more than 256 colors, it gets converted to 256 colors. Please note that I believe this is a limitation of Visual C++ 6.0 and its resource editor. I am assuming that I will have to load the icon from code somehow and just link everything externally via files. I could be wrong, but this is why I am here

AFAIK, you couldn't be able to use HIGH res Icon in Visual C++ 6.0

You can't use hi-res images from within VC6. You need to create them using another application and then modify the RC file manually.

Hi I’ve been trying to write a routine that will scan 1 bitmap to see if a second bitmap is within it. I’m not having a problem with the algorithm to do the search I’m having problems getting the pixel colors from both the bitmaps. For testing I loaded the first image by calling ::LoadImage() which returns an HBITMAP. For the second image I’m loading into I.E. and using some code to get the hwnd and pull the HBITMAP calling CopyWindowToBitmap().
So now that I have 2 variables of type HBITMAP. How do I get there pixels?
This is what I’ve tried with no success.
HBITMAP bmpOne;
HBITMAP bmpTwo;
… Some code to get bmpOne and bmpTwo ..
HDC hDC = ::GetDC(NULL);
HDC hDCBMPOne = ::CreateCompatibleDC(hDC);
HDC hDCBMPTwo = ::CreateCompatibleDC(hDC);
::SelectObject(hDCBMP1 , bmpOne);
::SelectObject(hDCBMP2 , bmpTwo);
COLORREF PixelOne;
COLORREF dPixelTwo;
PixelOne = ::GetPixel(hDCBMPOne, x, y);
PixelTwo = ::GetPixel(hDCBMPTwo, x, y);
If I do the following…
int red = GetRValue(PixelOne);
int green = GetGValue(PixelOne);
int blue = GetBValue(PixelOne);
Even though the color at x,y is not white I always get
red = 255, green= 255 and blue = 255;
I know that the HBITMAP bmpOne and bmpTwo are loaded because I display them in a dialog.
Any thoughts? Is there a way to get the pixel data directly from HBITMAP? Thanks.

I think you can do this by select the bitmap(s) into a device context (one at a time) and then calling GetPixel()[^].

GetPixel is terribly slow, can you create a HBITMAP so that it's also a DIBSECTION ? Then you'll have a pointer to the underlying bytes for this sort of work.
