If the scroll bars are appearing automatically, it is likely that your dialog resource is larger than the default frame client area size.
Add a handler for the WM_GETMINMAXINFO in the CMainFrame class. You can then specify the min and max size for your windows.
<br />
void CMainFrame::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI) <br />
{<br />
lpMMI->ptMaxSize.x = 700;<br />
lpMMI->ptMaxSize.y = 500;<br />
lpMMI->ptMaxTrackSize.x = 700;<br />
lpMMI->ptMaxTrackSize.y = 500;<br />
lpMMI->ptMinTrackSize.x = 700;<br />
lpMMI->ptMinTrackSize.y = 500;<br />
CFrameWnd::OnGetMinMaxInfo(lpMMI);<br />
}<br />

A quick way to remove the scroll bars is in the OnSize handler for the form view is to call:
SetScaleToFitSize(cx, cy) ;
You may also need to r-size any controls to porperly fit on the form.
As for the bitmap appearing in the middle of you tab control, check the tab order of the control in the resource editor (CTrl+D) and make sure that he bitmap is before the tab control to get he correct plot order.

Hi,
I just created an app using VC++ and I think it needs a little spice so, I want to include graphics in my app, how can I put an image in the background (not 16 colors, 256+) like in msn messenger. I would like an image and I could put my controls on top of it. Actually when I do that today, my bitmap takes the whole place and all the controls are under it. And also, I want to make my image fit the entire application canvas.
Help me if you can please.

Use stretchBlt, and paint the image in the WM_ERASEBKGND message.

First of all, my equipment:

Workstation is in the same network like win2k server (of course!)
******************************************************************************
First step:
BINDING TO AN USER (testuser@htlpinkafeld.at)
I read that i should use the function
HRESULT ADsOpenObject(
LPWSTR lpszPathName,
LPWSTR lpszUserName,
LPWSTR lpszPassword,
DWORD dwReserved,
REFIID riid,
VOID FAR * FAR *ppObject
);
To do so, i had to import the following:
Header: Adshlp.h
Library: ActiveDS.Lib
PROBLEM:
The 5th parameter takes values which are neither in Adshlp.h nor in ActiveDs.Lib. So!! I found out that the needed stuff is in another lib called
"ADSIID.lib". BUT some declarations are redefined in ADSIID.lib! Because the program needs this lib to work right i even can't let it be. Then i found out that this sometimes happens, god knows why!, and that i should insert the prefix "/force:multiple" into the menu project\settings\Link\"Project Options". I did so and the result was a list like the following, please don't scare:

I dont't know how the first three parameters of the function
HRESULT ADsOpenObject(

should look like! I have already watched the MSDN but the information in there isn't enough for me! Please help me!!!

I'm trying to make a little dialog to let the user search for a text string in a CEdit control on my main app's dialog. Like in Word or Notepad those kind of search windows. Does anyone have an idea on how to do this because i tried something myself and it didn't work at all (one of the reasons is that the CEdit::SetSel(...) didn't appear to work.)
Thanks

Why don't you change it to RichEdit control,
it has more feature for text.

Hi,
I have a .icm file.I would like to retreive the contents of the tag whose signature is "desc".
Any idea?
Neha

I jus opened a few icm files. They are not text files. They contain binary data and the postition of the description kept changing file to file, so did the file size. I suggest that you do a search to figure out the icm internal structure.

I have a need to do the following item and could use some help setting it up. I have a basic MFC application running that includes a prebuilt MFC dialog derived class for allowing the user to input data. this all works fine. I need, however, to allow the user to create their own MFC based dialog box, and then allow them to call that dialog box at runtime without the primary application being aware of the dialogs design. So what I have done is this...
in main app, when i select menu item 'test' it looks for a dll named 'testing.dll', and if it finds it, then it loads the dll, finds a function called Create() and attempts to run it. this works fine.
in the create() function, it is a simple test for now.
char gString[255] = "";
void Create()
{
CMyDialog d;
if (d,DoModal() == IDOK)
strcpy(gString,"everything worked fine");
}
all of the exporting works fine, it does loading the dll, finding the create function, retrieving the gString variable etc... the only thing that doesnt work as expected, is in the DoModal() call of the dialog class. the dialogbox appears, and then the entire program crashes. This doesnt happen if i create a simple dialog box that is not CDialog derived.
Am I missing something on MFC? is there an issue with trversing a dll boundary with the MFC.
thanks in advance for any info.

This won't work.
You have not associated a dialog resource. Without doing that DoModal() will fail.

sorry but i am not sure what you mean exactly.
In the dll I created, there is a class definition of an MFC CDialog derived class. I should have written this from home, I will post my code when i get there. but the class 'should' be all inclusive, as it runs fine in a native MFC application. anyhow, when i get the code posted maybe my question will make more sense

Oh!
I apologize for misinterpreting your question.
Yes, please post a little more code, so that it might be easier to locate the problem.

Is testing.dll an 'extension dll'? If you're creating a dll which uses MFC, you have three options - DLL using static MFC, 'regular' DLL using MFC in DLL and 'extension' DLL which shares MFC data with your .exe file and with other 'extension' dlls.

Resource Library Loaded - resourcedll\MFCTestDLL4.dll
SetData Function located - (null)
Inside DLL, SetData(from the main app) - (null)
CreateMyDialog Function located - (null)
Inside DLL, CreateMyDialog(TestDialog) - (null)
Inside DLL, TestDialog t - (null)
// and i get a nice little windows messagebox telling me i screwed up
as you can see from the log file, it is during the DoMocal() call that I have the trouble.
any thoughts?

The Problem is --Where and How to Delete the created objects with "new" Operator
Please mark the palce and solution..
i tried with somany ways but i am getting "Heap assertion"
and in Debugging mode it is showing MemoryLeak Detected
as follows:
Detected memory leaks!
Dumping objects ->
{172} normal block at 0x002F5F88, 500 bytes long.
Data: <d:\projects\dump> 44 3A 5C 50 72 6F 6A 65 63 74 73 5C 44 75 6D 70
and also i am getting the
First-chance exception in MyApp.exe (KERNEL32.DLL): 0x000006B5: (no name).
please give me the solution
I am very much worring about these problems please please....
This is Mycode:
I am declaring structures as follows:
1.For Database entries:
;;;;;;;;;;;;;;;;;;;;;;;
typedef struct{
char strName[MAX_PATH];
int nNumber;
int nCode;
}DB_DATA;
2:For Daily entries:
;;;;;;;;;;;;;;;;;;;;
typedef struct{
char strName[MAX_PATH];
int nNumber;
int nCode;
}DAILY_DATA;
Now i am using CTypedPtrList as follows:
1.For Database:
===============
typedef CTypedPtrList<cptrlist,db_data*> DB_DATA_LIST;
DB_DATA_LIST m_lstDbData;
2.For Initial List:
==================
typedef CTypedPtrList<cptrlist,daily_data*> INITIAL_LIST;
INITIAL_LIST m_InitialList;
3.For Priority List:
====================
typedef CTypedPtrList<cptrlist,daily_data*> PRIORITY_LIST;
PRIORITY_LIST m_PriorityList;
Initially i am getting all the data from database and store it in "m_lstDbData"
as follows:
############
while (EndOfFile)
{
DB_DATA * dbdata=new DB_DATA;
strcpy(dbdata->sName,rs.sName);
dbdata->nNumber=rs.nNumber;
dbdata->nCode=rs.nCode;
m_lstDbData.AddTail(dbdata);
MoveNext();
}
Preparing the InitialList as follows:
`````````````````````````````````````
Now i am checking the Dialy Register(one Text file contains record wise data) if
Daily Register values mactched with Database values then stored this values into InitialList.
do
{
POSITION nPos=m_lstDbData.GetHeadPosition();
for(int nPass=0;nPass<m_lstdbdata.getcount();++npass)
{=""
="" db_data="" *="" tempdbdata="new" db_data;="" if(dialyreg="" ncode="=tempDbdata-">nCode)
{
DAILY_DATA * tempDailyData=new DAILY_DATA;
strcpy(tempDailyData->sFileName,str);
tempDailyData->nNumber=tempDbdata->nNumber;
tempDailyData->nCode=tempDbdata->nCode;
InitialList.AddTail(tempDailyData);
}//end if(DialrRegCode==tempDbdata->nCode)
m_lstDbData.GetNext(nPos);
}//end for(int nPass=0;nPass<m_lstdbdata.getcount();++npass)
="" }while(endof="" daily="" reg);="" this="" is="" do="" while="" loop=""
<<<<<<<<<<<<<<<<<<<<<<<<<="">>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Next I am preparing PriorityList according the nCode(assending):
````````````````````````````````````````````````````````````````````
while(!InitialList.IsEmpty())
{
POSITION nPos=InitialList.GetHeadPosition();
DAILY_DATA * TempHeadPosData=new DAILY_DATA;
TempHeadPosData=InitialList.GetAt(nPos);//Head Position Priority
nStuctPos=InitialList.Find(TempHeadPosData);
nHPosCode=TempHeadPosData->nCode;
for(int nIndex=0;nIndex<initiallist.getcount();nindex++)
{
="" daily_data="" *="" tempnextposdata="new" daily_data;
="" nnextposcode="TempNextPosData-">nCode;
if(nHPosCode>nNextPosCode)
{
nStuctPos=InitialList.Find(TempNextPosData);
int nTempHold=nHPosCode;
nHPosCode=nNextPosCode;
nNextPosCode=nHPosCode;
}//end if(nHPosCode>nNextPosCode)
else
{
if(nHPosCode==nNextPosCode)
{
//here i am doing somethine
}//end if(nHPosCode==NextPosPriority)
}//end else
}//end for(int nIndex=0;nIndex<initiallist.getcount();nindex++)
="" daily_data="" *="" tempnewdata="new" daily_data;
=""
="" prioritylist.addtail(tempnewdata);
="" initiallist.removeat(nstuctpos);
="" }="" end="" while(!initiallist.isempty())
finally="" i="" am="" getting="" the="" data="" from="" prioritylist="" and="" send="" it="" to="" mydll(mydll="" do="" update="" database)=""
``````````````````````````````````````````````````````````````````````````````````````````````````
while(!prioritylist.isempty())
="" {
="" position="" pos="PriorityList.GetHeadPosition();
" filedata="new" strtemp.format("%s",filedata-="">szName);
nCode=filedata->nCode;
if(nCode>=1)
{
//call MyDll
PriorityList.RemoveAt(Pos);
}//end if(nCode>=1)
else
{
PriorityList.RemoveAt(Pos);
}
strTempPath=strPath;
}//end while(!PriorityList.IsEmpty())
