Dear Sirs,

My problem is this,

After doing search on my form, I load my toolbar where I have same buttons (Next, Previous, LAst, First). But after that when I load another form, I can't write same thing inside, All fields seem to be Clocked.

I don't understand.
On my codes, when I destroy this toolbar before calling an other form, all things are well. But when I destroy it, it can't appear again even if i need it again ?

What to do ?

I learn My self

If you destroy it, you will have to create it again and not just show it.

This what i write but not success :

CMainFrame* pFrame = (CMainFrame*) AfxGetApp()->m_pMainWnd ;
CStatusBar* pStatus = &pFrame->m_wndStatusBar ;
CToolBar*pTool = &pFrame->m_wndToolBar ;
pTool->CreateEx(pFrame,TBSTYLE_FLAT,WS_CHILD|WS_VISIBLE|CBRS_TOP);
pTool->LoadToolBar(IDR_TOOLBAR1);
pTool->ShowWindow(SW_SHOW);
pTool->EnableWindow(true);

CScrollView.. strange effect

3-May-06 2:07

When I write this test
if (!pTool->LoadToolBar(IDR_TOOLBAR1))
AfxMessageBox("Failed to Load Toolbar");
I see that there is a problem, the Toolbar is not loaded, i don't know why ? What to do ? Why it is not loaded ?

Hi,
I have two views of CScrollView type open with tile effect.
I set SetScrollSizes(MM_TEXT, sizeTotal) . In first view I scroll and get the view to the area which should not be visible in second view. then I start drawing my graphic objects. I draw lines rectangle in one view and then call UpdateAllViews on document.

To my horror, I saw the graphic elements in other view too of same dimension.
relative offsets of these objects are same in both views from their top left corner or say bottom right corner. Update on both view causes both all graphic objects to be drawn all overlapped just like second view. They are not visible in the scrolled area.

Are these getting drawn in screen coordinates? Here which dunction need to be used.. screen to client.. how to have correct effect.

(mapping mode I am using is MM_TEXT)

//=========================================================================
CPropertySheet dlg(_T("Hellow"), this, 0);
one a;
two b;
three c;
dlg.AddPage(&a);
dlg.AddPage(&b);
dlg.AddPage(&c);
dlg.SetActivePage(&b);
dlg.ModifyStyle( 0, TCS_BOTTOM ); // to modify the Tabs in Down Side
dlg.DoModal();
//==========================================================================

Naughty splitter windows with OpenGL and MFC

Hi,

I'm using VC++ .NET 2003 with MFC and OpenGL to do some ghraphics programming and have come to a rather sticky mess with Splitter windows. No matter how many splitter windows i set up, the opengl graphics only every appear in the last "pane". currently i have assigned the same view with opengl drawing code to every pane, but its only the last pane which will display any graphics. the others never ever et updated, and dont even turn to a black colour. i.e. moving other windows over these panes leaves a mess behind.

has anybody had a similar problem and know of how to fix this?

any help would be much appreciated.

Thanks,
Paul

You need to make sure that your wglMakeCurrent stuff happens at the beginning and end of the draw function instead of at the beginning/end of the app. This is because openGL can only draw to the current rendering context - so at the moment thats probably the first view/dc that you set it up with.

Its probably better to use the forums at www.openg.org if you need any more help with this kind of stuff.

Hope that helps,
Kev.

CIPAddressCtrl::GetAddress() returns the number of non-blank fields.

use ifstream like that

ifstream fin;<br />
fin.open("MyFile.txt");

now use fin just like you use cin.
In case of any problem, let us know.
Good luck

1. speak proper english
2. learn C/C++ before continuing asking questions like the ones you've been asking those days.

you seem to don't even understand what you do and what you want Unsure | :~

He's not trying to discourage you. You will discourage yourself alone if you continue on this way. Learning a programing language is something long and hard. It takes a lot of time to get fluent with it.
The way you are learning it is not really good. In brief, you 'ask' people to do the job for you but you don't even understand what's going on.

I suggest you to find a good book (sorry, I don't know one) that explains everything with some examples. Then, start to do very simple programs that you FULLY understand (like asking the user for a value and displaying it back, opening a file and outputing its content in the console, ...)
If you try to go too fast, you'll be disgusted.

thanks for your support Cedric.

i didn't want to offend (even if I knew while posting that it would), but it becomes boring to see that the best this guy can do to learn is reading a C++ book first.

and the other important point i quoted was his SMS'ed typing english, which is not very appropriate to an international forum like codeproject.

i appologize dude if you thought i wanted to discourage you (it's not the case), but consider taking my thoughts as good advices.

regards to all.
