I use the ExtractIcon() function, maybe it can help you...
This is just an example ...

BOOL foo_notifyIcon()
{     
	ZeroMemory(&niData,sizeof(NOTIFYICONDATA));
        niData.uFlags = NIF_ICON|NIF_MESSAGE|NIF_TIP;

	hModule = GetModuleHandle((LPCSTR)"executablename.extension");
	ico = ExtractIcon(hModule, (LPCSTR)"C:\\windows\\system32\\shell32.dll",18);
	niData.hIcon=ico;

	BOOL rc = Shell_NotifyIcon(NIM_ADD,&niData);	
	return rc;
}

Hi,

Is there an easy way to create a number of "forms" containing controls and being able to show/hide them within a dialog? I want to be able to show/hide groups of controls programmatically and I dont want to have to call ShowWindow() for every control? If there is a way to group controls so that one ShowWindow() will show/hide the whole group that would be great!

Cheers Big Grin | :-D

Yes if you have many controls for example 200 controls and you want to invisible these controls a way is use of 200 showwindow for hide or show them but if you have a set of numbers for you controls(ID) you can use of a showwindow for them see a short example:

for(int i=100;i<500;i++)
GetDlgItem(i)->ShowWindow(0);//SW_HIDE
GetDlgItem(i)->ShowWindow(1);//SW_SHOW

Yes - you create separate dialogs with the different forms, and then you create all of them at once, and then show/hide individual dialogs. This is basically a property sheet! Smile | :)

N.B - I just did an implementation for a prototype that does something like this by examining dialog resources at runtime and them adding/removing/moving/resizing the active view's controls as required. Makes for easy dynamic interfaces (just put the new DLL in) very easy! Too bad I cannot share the source for it now...

Peace!

Hello,
i use CListCtrl with the Owner Draw property and virtual list, and every time when i want to update
the content of my CListCtrl this control flicker.
I add new items in a vector and then call pMyListCtrl->SetItemCount(vector.size()); to update all items, and here is that flicker!
Can i avoid this?

thanks for any help

You can turn redrawing off, do your updates, turn redrawing back on and force a redraw. Something like:

    m_lcMyVirtualList.SetRedraw( FALSE );
    // Do The Updates...
    m_lcMyVirtualList.SetRedraw( TRUE );
    m_lcMyVirtualList.RedrawWindow();

Peace!

Hello,
thanks for answer, but its the same, when i call

m_lcMyVirtualList.SetRedraw( TRUE );
m_lcMyVirtualList.RedrawWindow(); // here flickers again!

stay the same problem!

Now i take a timer to update my list control!

   If you are seeing flicker at that point, it may be that the implementation of your data store may not be as fast as it should be. Since you are using a virtual list control, you need to provide data to the control as it asks for it.

   If the data store you are using is too slow, you may see flicker because of that - the updates will be slowed down because of slowness.

   May want to look into speeding up the handling of data.

   Peace!

One way would be using MoveTo (int nXCoord, int nYCoord)/MoveTo (CPoint point) and LineTo (int nXCoord, int nYCoord)/LineTo (CPoint point) of the DeviceContext in cascade for every plane, and then once every one to connect the visible corners.

Use the OK to set a BOOL to true and in the OnPaint...

//I use 100 to let you aprecciate the effect on the screen
//Back Side
pDC->MoveTo (0, 0);    //Left-Up Corner
pDC->LineTo (width, 0);  //Right-Up Corner
pDC->LineTo (width, height);//Right-Down Corner
pDC->LineTo (0, height); //Left-Down Corner
pDC->LineTo (0, 0); //End in the beggining to close the square

For the second square you should make the same but adding "length" in every coordinate to draw it "in front of the other one"

Then you have to connect every corner with

pDC->MoveTo (0, 0);            //Left-Up Corner 1st square
pDC->LineTo (length, length);  //Left-Up Corner 2nd square

pDC->MoveTo (width, 0);             //Right-Up Corner 1st square
pDC->LineTo (widthlength, length);  //Right-Up Corner 2nd square

and so on with the other pair of corners

Note:
I am using the CDC* pDC that is in the OnDraw message for VC++ in the CView derived class. In dialogs you should look at OnPaint and if the cube has to be drawn there, use the CreateCompatibleDC to and draw using it.

Greetings.

   Since MySQL support BLOB columns, I would suggest compressing the data (zLib comes in handy here), and then stuffing the resulting data into a BLOB column, possibly storing the "real" length of the data somewhere to optimize your uncompression process.

   How you get that data into a BLOB column depends on the API you are using (MySQL Connector/ODBC), but you should have documentation that explains how to do that.

   Peace!

   The complete path to the file is enough information to get at that file's data. In a nutshell, you can load the file's data, and then upload it to the database. As I said before, the documentation for the API you are using will show you how to pass data to the database.

   When downloading the data from the database, you will save it on disk (oh, and also remember to keep the filename and extension of the original file so you can recreate it correctly), and then you can launch it from wherever you saved it on disk at.

   Peace!
