If you want to just change the text in the title bar, use SetWindowText(HWND hwnd,LPCTSTR string);, where hwnd is the handle for the window, and string is a pointer to the string.

hi,
Can anyone tell me how to have a picture (*.gif file)in my Dialog box ?
Thanks

On a button? As the background? Where do you want the picture rendered?

Hi
I have a class called Node which is derived from CButton
now I want have associated a property sheet with it. depending on the Node windowtext I want to set the values in list boxes of all the pages related to the property sheet. How do I do it?
I believe i will attain it through overriding the OnInitDialog of the pages associated with the sheet but since these vary I cannot simply add data to the lists. How do I do it??
can somebody guide me.
Thanks in advance.

Not sure I quite understand what you're trying to do.. but...
why not give Node a constructor or member function that takes a pointer to a CListBox (or CListCtrl or whichever you are using) and store the pointer as a member in Node. Then the Node class can handle its own click (ClassWizard lets you do this - otherwise I forget the exact handler function) and that can access the proprety page in whatever way you like.

I was trying to upgrade a C++/MFC project from VS6 to VS.NET 2003 and hit a linker problem that I cannot explain. Can one of you?
I was expecting the MFC linkage to occur to MFC7x, but the linkage fails with linker error "cannot find mfc42d.dll". I understand that the linker cannot find that dll (it's nowhere in the library search patch), but why does it look for it in the first place? How is the desired MFC version adjusted or determined?
There is no reference in the project preferences to that dll, or to anything else that looks remotely like "mfc42". I am building a DLL, which itself links to several DLLs via import libraries. These other DLLs are linked to MFC42, would that require the primary DLL to be linked to MFC42 as well?
Any thoughts are welcome.
TIA,
Bernd

Somewhere in your project is code that is still compiled for VC6. You will need to recompile everything to remove all references to MFC42D.dll. Also note that this is the debug version of the DLL.

Thanks. The project itself has been cleaned and re-built at no avail.
You didn't mention the import libraries, but I believe these should not cause the problem anyhow. How about function libraries, thought?
Surely these must be rebuilt for MFC7, too? Hmm, that's like opening a can of worms.
I guess I can not link the application to both MFC42 and MFC71 at the same time, right?
|

The source of the problem can be in any piece that's referenced in the linking process: object files in your project, import libraries, or 'function' libraries.
You've rebuilt your entire project under VS.NET, so the object files in your project should not be the problem.
Import libraries are object libraries that contain stub functions that correspond to the actual functions in a DLL. These stub functions take care of loading the library and then calling the actual DLL function for you. An import library is associated with a specific DLL. If you link to an import library that was compiled under VC6, you will need the MFC42* DLL's.
By 'function' libraries, I assume you mean object libraries. If any of these object libraries were compiled under VC6, you will probably also need the MFC42* DLL's.

I don't believe so. You would have two different copies of MFC loaded, with the corresponding mix of state information. I doubt this would work well, if at all.

Two words for you:
static link!
But as you (and others) have said, *everything* will need to be rebuilt with MFC 7.0 or you will have problems. This includes any supporting static libraries your project uses.

Idea:
to compensate font change by inverse change of CDialog's font,
to make controls look same.
It wors for modeLess Creation,
but for Modal - ActiveX - in my case Windowless
ActiveX- do not created after ew template use.
Where is error or bot made some work?
Private members get in Macro defining CDialog function,
that called GetDoModalData() to get Them,
Functionality of creation Cdialog with font change
placed in inheritable class
class CDlgHead : public CBitmapDialog , public CDialogCreatorHelper <cdlghead>//CDialog
All works except for ActiveX-Windowless - as I tested:
<br />
CDlgHead dlg;<br />
dlg.GetDoModalData();<br />
dlg.Create_WithFont(IDD_Form_1,pParent,0,-1);<br />

hai all
i have an executable file installed in my system and what i need to do is
invoke that application(.exe file) when ever my operating system is up.please
help me
thank you

You could place a shortcut to the file in the Startup folder on the start menu, or better still, create an entry in the RUN section in your registry key path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
This will work on whoever logs into the machine assuming they have access rights to the file that you want to run.

There are multiple Run sections...
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run will execute the application before anyone logs into the system
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run will execute the application when that user (the current one) logs in...
Just make a new String Value (REG_SZ) and give it a descriptive name "My Application" then set the value of the String to the location of the executible C:\.....\somthing.exe

Is there any way i can get all the table names of a database in Access or SQL progmatically??
|
|
|
|

Yes. If you're using OLE-DB or ADO you can use OpenSchema to give you a schema rowset, if you're using ODBC you can use SQLTables...

This will get all tables from access or any other
_ConnectionPtr pCon;
_RecordsetPtr pRs;
_bstr_t bstrTableType("TABLE");
_variant_t varCriteria[4];
varCriteria[0].vt = VT_EMPTY;
varCriteria[1].vt = VT_EMPTY;
varCriteria[2].vt = VT_BSTR;
varCriteria[2].bstrVal = mytable;
VARIANT varData;
SAFEARRAY FAR* psa;
SAFEARRAYBOUND rgsabound[1];
rgsabound[0].lLbound = 0;
rgsabound[0].cElements = 4;
psa = SafeArrayCreate(VT_VARIANT, 1, rgsabound);
for( long lIndex = 0 ; lIndex < 4 ;lIndex++)
{
SafeArrayPutElement(psa, &lIndex,&varCriteria[lIndex]);
}
varData.vt = VT_VARIANT | VT_ARRAY;
V_ARRAY(&varData) = psa;
try
{
TESTHR(pCon.CreateInstance(__uuidof(Connection)));
TESTHR(pCon->Open(,"","",NULL));
pRs = pCon->OpenSchema(adSchemaTables);
while(!pRs->EndOfFile)
{
_bstr_t bsTableName = pRs->Fields->GetItem("TABLE_NAME")->Value;
pRs->MoveNext();
}
pRs->Close();
pCon->Close();
}
catch(_com_error e)
{
HandleComError(e);
}

VARIANT v;
v.vt = VT_BOOL;
v.boolVal = 0;
Maybe this will work? You're initialisation of the VARIANT is not correct. If you want to place a boolean in your VARIANT, then set the type to VT_BOOL.

I tried with VT_BOOL.. still it doesnt work...
Also I tried declaring a function with same signature and that function call works but the one i am trying doesnt.....
Can u please tell me what can be the problem...
I am stuck from last 6 hours on this

Two things. Firstly, you aren't initializing the variant properly, you've said it's a variant, but set the boolVal member.
Did you mean
vart.vt = VT_BOOL;
vart.boolVal = 0;
You don't specify which file/line the error occurs on. The message implies you are performing some kind of
dest = src;
where src is a VARIANT thing. If this is the case, you might be trying to assign the variant rather than one of it's union members.

Hi Steve,
Yes I meant doing ---
vart.vt = VT_BOOL;
vart.boolVal = 0;
But even after doing that the error persists.
The error occurs at --
c.MemberFunc("hello", vart);
call
I know abt dest = src;
But steve I also tried writing another function with the same signature as
MemberFunc(...);
and passesd same parameters [ ie. NewFunc("hello", vart); ]
But the compiler gives no error for this call.
I am really confused
Help me out

I'm not exactely sure what the problem is, but perhaps you haven't initialised your VARIANT using 'VariantInit'. Don't know for sure if this is necessary though.
