Didn't you say you made a fresh application project and it worked?
If so, maybe you need to commpare that to your code and/or start with an empty MDI child class and add your code until it doesn't work.

I can only guess since I don't have the code.

I tried out.
I made new MDI application and added my codes in to it. But my bad luck it does not come.I dont know why?

But when i compare with other application i can find out one difference..
Another appliation: When i resize the window the content in the window also get adjusted and show me the full content even when i resize to small window.
My application: when i resize it, the contents which are included in that size appears.
Ex. If the content is like this text "MDI application",when i resize the text gets shrinked in size and show me the full text.
But in my application,when i resize it,it shows only "MDI appl".

Can u get me?

So the sizing of the window is working ok but repainting the window contents isn't working?

If yes, how are you doing the repainting of the window?

Also, are you using MFC or straight Win32 APIs?

Yes i didnot add repaint coding.IS this related to maximize and minize problem that i asked in previous message.Im using MFC.

This is the part I'm not understanding - where is this text "MDI application" geting drawn? In the title bar or the client area of the window?

In the client area..Actually im drawing some graphs and tables .For example oonly i denote like MDI application.

When im resizing i can seee only part of the graph.

Iam doing all drawing functiosn is OnDraw()..
void CUnitTrendView::OnDraw(CDC* pDC)
{
GetClientRect(&ClientArea);
CFont *pOFont = pScreenDC->SelectObject(&TextFont);
CPen *pOPen = pScreenDC->SelectObject(&GPen[0]);
pScreenDC->FillRect(ClientArea,&GBrush[2]);
pScreenDC->SetTextColor(RGB(0,255,0));
pScreenDC->SetBkColor(RGB(0,0,0));
if(AreaTrendFlag)
{
POSITION TrendListPos = goTrendList.GetHeadPosition();
if(TrendListPos != NULL)
{
CTrendInfo *pAreaTrend = (CTrendInfo*)goTrendList.GetAt(goTrendList.GetHeadPosition());
cTimeBreakUp = pAreaTrend->GetTrendTimeBase();
sUnitTrendTitle = (CString)"Area Trend Overview " + " ( " + GetTimeBreakUpText(pAreaTrend->GetTrendTimeBase()) + " )";
int *pUTrTagIndex = pAreaTrend->GetTrendTagIndex();
for(int i = 0;i<24;i++)
iUnitTrendTagIndex[i] = pUTrTagIndex[i];
}
AreaTrendFlag = FALSE;
}
pTrend->Draw(pScreenDC,iUnitTrendTagIndex,sUnitTrendTitle);

}

Im coding all drawing functionalities in OnDraw()

One thing...

Are you considering actual size of the window to make a zoom? If you create your fonts with static/fixed size, it is logical that if u make the window smaller not the whole text will be visible.

One idea:

Take the size of your window just at the beggining of the application (init instance or somewhere like that) and save the values as first values. Then, when the window is resized (OnSize or something similar) take the new values and if they are different, get the ratio factor with ActualSize / OriginalSize.

With this ratio you can make different things: One... make a zoom in or zoom out depending on if the ratio is bigger or lower than 1. Or just multiplicate all your size/position variables with this ratio and you will keep the proportion without mattering about the size of the screen.

The only problem with that is if you resize the window only in one direction, then you will get a distorsionated View.

Greetings.

hi all. i have a very simple question: i have created an array of strings like this ->

string all_errors[256]; // stores 256 error strings
then i store a value for all_errors[0] = "test";

i want to write this out to a text file. i do it like this:
results << all_errors[0] << "\n";

is there anything wrong syntactically with the above statements? if not, i will give more code..

i get two errors:

Holy cow, that's 2 errors? Smile | :)

Try

results << all_errors[0].c_str() << "\n";

You shouldn't have to do this.

Compiles fine for me with VS 2005 and no service pack;

I'd try changing "\n" to std::endl

This is not related to the OP, but I think there is a tendency to overuse std::endl, I suspect that somehow people think it is more C++ish. The big difference is that std::endl, as well as outputting a new line character, flushes the stream's buffer. For a few random output lines this doesn't matter, but for writing normal files use '\n' and let the stream's buffer do what it is supposed to do. The exception is when you use file-based debugging - here endl is essential as it ensures that in the case of a crash the last line of the file is actually written to disk.

Thanks I didnt know that. I always thought the advantage was that it would put the correct line ending for the platform you are running on.

I am having a more-than-momentary lapse of reason... I want to use the PostMessage( ) function to pass a window handle (CWnd) from one app to another.

In the caller, i have something like this:

   CWnd   hWnd;
// assign hWnd to current window handle (dialog app/dialog-based app window)

   static CWnd *pWnd;
   pWnd = FindWindow("RecvApp",0);
   pWnd->PostMessage(WM_CONNECT_APP, hWnd, 1);

In the receiver application ("RecvApp"):

   // in a header definition file
   CWnd   *pWnd_Caller;

// in MainFrame.cpp - main frame for "RecvApp"

   ON_MESSAGE(WM_CONNECT_APP, OnMakeConnection)

   LRESULT CMainFrame::OnMakeConnect(WPARAM wParam, LPARAM lParam)
   {
      // wParam is the handle to the caller's window/dialog-window

      if (lParam == 1)
         m_View->PostMessage(WM_CONNECT_APP, wParam, lParam);

   }

// in "RecvAppView.cpp" - view frame for "RecvApp"
   // somewhere in a message mapped function, I want to use wParam (hWnd) as
         wParam->PostMessage(WM_ADD_ENTITY, 0, 0);

I want to use the window handle of the caller to post a message back to itself based upon parameters gathered in the receiver app...

(caller) PostMessage (to receiver)

(receiver) assign values, do its stuff...
(receiver) PostMessage (to caller - new values)

In short, I need to know how to pass and use/dereference (etc...) the CWnd handle I am passing around.

Thanks.
Johnny
