Notice what is to the left of d2? dialog2 has not been declared at this point.

I see that now. My bad. The circular reference suggestion is what you need.

You've got a circular reference problem.
You can't forward reference a class object, but you can forward reference
a class object pointer, since the compiler knows what a pointer is.
Something like this should work...
#pragma once
class dialog2;
class dialog1 : public CDialog
{
public:
dialog2 *d2;
...
};
#pragma once
#include "dialog1.h"
class dialog2 : public CDialog
{
public:
dialog1 *d1;
...
};

thnx that solved my problem
but after that i arrived to new problem
in first dialog there is a progress bar and my program in second dialog want to control this progress but error happen
i used ur code with ur pointer to first dialog
i can change variable in first dialog but cant change visual elements
|
|
|
|
|
Changing visual elements in another dialog class doesn't sound
like a good design.
Maybe send or post messages instead. Let each dialog class change its own
visual elements.

Hi,
I have a SDI FormView based app which contains some custom control along with some standard controls. The problem I am facing is briefly explained below.
I designed the FormView Dialog on a computer which has 800*600 resolution. When I run the app on the same computer the screen is OK. But when test the same app on a computer that has a resolution of say 1028 * 768, the total app window occupied only 70% of the screen.
I have seen one program which has different user interface depending on the screen resolution. It contains more controls on the form if scrren resolution is more or switches to normal form when the resolution is set to lower say 800 * 600 .
I am trying to implement the same behaviour like displaying extra controls if resolution is more, or the important ones for normal resolution.
1. Is it possible using Visual C++ 6.0 version.
2. Does creating two dialog templates one for high resolution, other for low resolution, and loading the dialog depending on the resolution work ?.
regards,
Shanmukha

Does change resolution is your problem?

I have try to use ado AppendChunk() fucntion to save to a clob data type to oracle database, but when i read back, the data was not save to the oracle database. Anyone know what is the problem?
// BEFORE THIS FUNTION, ORACLE DATABASE WAS CONNECTED
bool ADODBHandler::UpdateMap()
{
AdoNS::_RecordsetPtr rst;
try
{
..........................
rst.CreateInstance("ADODB.Recordset");
rst->CursorType = AdoNS::adOpenKeyset;
rst->LockType = AdoNS::adLockOptimistic;
HRESULT hr = rst->Open("pcmap.WAFERMAP3_PROCESSMAP", _variant_t((IDispatch*)m_cpConnection,true), AdoNS::adOpenKeyset, AdoNS::adLockOptimistic, AdoNS::adCmdTable);
rst->AddNew();
rst->Fields->GetItem("LOTNO")->PutValue(lotno);
rst->Fields->GetItem("WAFERNO")->PutValue(WaferNo);
rst->Fields->GetItem("WAFERID")->PutValue(Waferid);
rst->Fields->GetItem("PROBER_FILE")->PutValue(ProberFile);
rst->Fields->GetItem("ORIENT")->PutValue(Orient);
rst->Fields->GetItem("ROW_COUNT")->PutValue(RowCount);
rst->Fields->GetItem("COL_COUNT")->PutValue(ColCount);
rst->Fields->GetItem("PASS")->PutValue(Pass);
rst->Fields->GetItem("FAIL")->PutValue(Fail);
rst->Fields->GetItem("SOURCE")->PutValue(Source);
rst->Fields->GetItem("ET_TIME")->PutValue(date);
rst->Fields->GetItem("MAP_VER")->PutValue(Ver);
rst->Update();
_variant_t varChunk;
varChunk.bstrVal = _bstr_t(cWafer); // cWafer is a char array about 2500 bytes long
// for some strange reasons, cannot save varChunk to database and no exception error was capture
rst->Fields->GetItem("MAP")->AppendChunk(varChunk);
rst->Update();
}
.........

Hi,
I am trying to impersonate a user on Win 2k machines. The LogOnUser() api works perfect on XP, 2k3 but it fails on win 2k machines as it requires SE_TCB_NAME privilege. So i tried to set the privilege to the current process by the code available on MSDN http://msdn.microsoft.com/en-us/library/aa446619(VS.85).aspx[^] but it didnt work for me. still it fails by giving error 1314 (A required privilege is not held by the client), if i give the "Act as a part of operating system" privilege from Administrative tools -> local Security Policy -> Local Policy to that particular user, the code works perfectly on win 2k. But how to achive it through code.
Thanks,
Sandeep

Hi all,
I have done spliting using OnCreateClient function of MainFrame class,
I have split my view in two column.
Is this possible whenever i want split window show or whenever i dontwant only one form show.
By default the split window show when i run an application,in toolbar i have a button when i clicked the button than in place of split window onlu one form can show.
Can this is possible.
Please tell me.
Tahnks in advance.
IN A DAY, WHEN YOU DON'T COME ACROSS ANY PROBLEMS - YOU CAN BE SURE THAT YOU ARE TRAVELLING IN A WRONG PATH

I believe that the OP indicated that he could successfully split his view into two columns. He wants to remove/hide one of those panes when a toolbar button is clicked.

Hi,
I am dovelping a wizard based applcation with 3 pages. At one page CTreeCtrl is there but when I call DeleteAllItems() It does not show any item even if I insert the item code is here:
CTreeCtrl *Tree=(CTreeCtrl *)GetDlgItem(IDC_TREE1);
Tree->DeleteAllItems();
Tree->InsertItem(_T("aa"));
And One CComboBox that does not drop down. what is the reason?
|
|
|
|
|
Try calling UpdateWindow() after the InsertItem method.
In ComboBox, after dropping the control from the resource pane into your dialog, you have to resize it vertically to set its dropdown area. Click on the pulldown button of the combobox. You will get a fram with 8 resizing points. Resize the frame vertically and try.
|
|
|
|
|
UpdateWindow() is not working and I can can pulldown the Combobox only horizontally not vertically
