Hi !
I am trying to use a list control inside a window, not a dialog, so I can resize it. I tried to create a class the inherit from CListCtrl and on it's instance to use the Create function:
CErrReport::CErrReport(CWnd *pParent)<br />
{<br />
Create (WS_OVERLAPPEDWINDOW|WS_HSCROLL|WS_VSCROLL,CRect (20,30,200,300),pParent,1);<br />
<br />
}
On the paret window I used :
CErrReport *perr=new CErrReport (this);<br />
perr->ShowWindow (SW_SHOWNORMAL);
But the problem is that when the window starts I can't even click on it or move it or close it, nothing.....
What am I doing wrong ?????????????????///
Please help me
Thank you

Why not use resizable dialogs?
Alberto
|
|
|

If I use a resizable dialog, then the dialog itself is resized but the control size is fixed, no ?
If I create a dialog based application, and I click on the maximize button, all the control remian in the original size they were created, is there a way to expand them to the size of the whole dialog frame ?
Thank you

You should be able to intercept the WM_SIZE and then, for each control in the window, call SetWindowPos or something like that. The WM_SIZE gets called with the new size as parameters, so you can redraw your controls or child window accordingly.

Shouldn't it be created using the WS_CHILD style? All the controls are supposted to be child windows. Just an idea.

Well, I tried to OR inot the style WS_CHILD and it did not help....
Thank you...

How about message reflection? I can't remember if it's nescessary to make the control work properly.

what is message reflection ?

Look at TN062 in MSDN.
Sorry for not elaborating, but I really have to get home now (it's almost 5 pm in Denmark).

I think the style is wrong.
WS_CHILD|WS_VISIBLE| ....
don't WS_OVERLAPPEDWINDOW (WS_CAPTION, WS_SYSMENU, WS_THICKFRAME, WS_MINIMIZEBOX...)

suggestion
CErrReportListCtrl:public CListCtrl
{
};
CErrReport:public CWnd
{
private:
CErrReportListCtrl m_ListCtrl;
public:
CErrReport(CWnd* pParent,CRect& r=CRect(0,0,200,200))
{
Create(pParent,r);
}
void Create(CWnd* pParent,CRect& r)
{
Create(WS_OVERLAPPED|..,...,r,pParent,..);
m_ListCtrl.Create(WS_CHILD|WS_VISIBLE|..,.....,this,1);
}
void OnSize(nType, cx, cy)
{
//Maybe
if(GetSafeWnd()!=NULL)
m_ListCtrl.MoveWindow (0, 0, cx, cy);
}
};
CErrReport *p= new CErrReport(this);
The Listctrl is nested in the CWnd

I will try this one, it looks like it's going to work. I found a similar solution in a book but it was too complicated, yours looks better.
Thank you.

Can someone verify my thinking here - I think that a windows message can only be handled by a window-based class. Is this right?
For example: in a MFC app I can handle a message in the view, mainframe, etc. but I can't handle it directly in a non-window class that the view instantiates. (I know I could always call a function in the other class from the view's handler.)
thanks

Yes, this is true. The exception is WM_COMMAND, which can be handled by CCmdTarget derived classes, like CDocument, CWinApp or CYourOwnCmdTarget.

Thanks, Tomasz. I thought that was right, but sometimes it helps if you can find someone else that agrees.

If you really need to provide message handling stuff in classes not derived from CWnd, you may want to use CSubclassWnd by Paul DiLascia (the guy who writes C++ QA column in MSDN Magazine). Just search for CSubclassWnd in MSDN.

You can use NetShareGetInfo
If you're running on Windows NT/2K/XP you can use level 2 and a structure of type SHARE_INFO_2;
on Windows 9x/ME level 50 and pass in a structure of type share_info_50.
The two structures unfortunately are defined in two different header files and, if you're targeting win9x you'll also need to link to a different library (netapi32.lib for NT/2K/XP and svrapi.lib for 9x)
Hope that helps,
Alberto

How do I compile Visual C++ .NET projects using the .vcproj file from the command line?
Thanks,
James

<disclaimer>I've not tried this with VS.NET, just VS6 where it worked a treat</disclaimer>
1. In a command prompt window, execute the vcvars.bat file in the Visual Studio .NET folder\VC7\bin folder. (i.e. Set up environment variables etc)
2. Try the command devenv /build .vcproj filename. If you do devenv /?, it shows you the command line parameters.

Hi all,
Does anyone know if it is possible, when dialling up the internet with a modem, to run local applications using the login script (the one typically used to provide information to the ISP) so that, when the system dials, an application runs - instaed of having a system that polls the port to see if there's a connection.
Thanks,

I am repeatedly accessing this function in my database app:
void CTrain1View::GetPhotoDB(CString m_PhotoDBName,CString m_MineName)
{
if (m_photoDb.IsOpen()) m_photoDb.Close();
m_photoDb.OpenPhotoDb(m_PhotoDBName, m_MineName);
}
where
int DbClass::OpenPhotoDb(CString PhotoDBName, CString MineName)
{
try
{
if (FAILED (m_pConnPhoto->Open (_bstr_t ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source = "+ PhotoDBName ),_bstr_t (""), _bstr_t (""), adModeUnknown)))
{
AfxMessageBox ("Can't open datasource");
return -1;
}
CString partQuery = "'"+MineName+"'";
CString SQLQ = "SELECT * FROM tblMine WHERE (DefID = "+partQuery+")";
char* SQLQuery = new char [SQLQ.GetLength()+1];
strcpy(SQLQuery, SQLQ);
m_pCommandPhoto->ActiveConnection = m_pConnPhoto;
m_pCommandPhoto->CommandText= SQLQuery;
m_pRecordsetPhoto->CursorLocation = adUseClient;
m_pRecordsetPhoto->Open ((IDispatch *) m_pCommandPhoto, vtMissing, adOpenKeyset,
adLockOptimistic, -1);
delete[] SQLQuery;
return num;
}
catch(_com_error)
{
PrintProviderError(m_pConn);
}
}
The second time I call the first function, and it calls OpenPhotoDB, there is a com error at:
if (FAILED (m_pConnPhoto->Open (_bstr_t ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source = "+ PhotoDBName ),_bstr_t (""), _bstr_t (""), adModeUnknown)))
{
AfxMessageBox ("Can't open datasource");
return -1;
}
even though as you can see, I did close the db before trying to open it again. Any one know ADO to help me out. I'm opening and then closing it before trying to open it again, so why does it choke?
Thanks,

First of all why are you closing the database connection prior to each query? This is a very inefficient way for your code to work. It should be more like if db.closed thhen db.open(). You should use the open database connection to execute as many queries you want.
This will not solve your current problem but will make your code more efficient, unless I missed something while reading your message.

Okay - so I should open the database just once and perform as many queries as Ilike on it. Right?
The reason I want to close and reopen is that most of the time its the same db, but sometimes the a different db name to open might come in as a parameter.
What about the recordset object. Since I do rs.Open for each query, should I close it each time and reopen it I pass it a new SQL string?
Thanks

THe error checking in place is:
void PrintProviderError(_ConnectionPtr pConnection)
{
HRESULT hr = S_OK;
_bstr_t strError;
ErrorPtr pErr = NULL;
try
{
long nCount = pConnection->Errors->Count;
for(long i = 0; i < nCount; i++)
{
pErr = pConnection->Errors->GetItem(i);
CString temp;
temp.Format("Error #%d\n", pErr->Number);
AfxMessageBox(temp);
temp.Format(" %s\n",(LPCSTR)pErr->Description);
AfxMessageBox(temp);
temp.Format(" (Source: %s)\n",(LPCSTR)pErr->Source);
AfxMessageBox(temp);
temp.Format(" (SQL State: %s)\n",(LPCSTR)pErr->SQLState);
AfxMessageBox(temp);
temp.Format(" (NativeError: %d)\n",(LPCSTR)pErr->NativeError);
AfxMessageBox(temp);
if ((LPCSTR)pErr->GetHelpFile() == NULL)
{
AfxMessageBox("\tNo Help file available\n");
}
else
{
CString temp1;
temp1.Format("\t(HelpFile: %s\n)" ,pErr->HelpFile);
AfxMessageBox(temp1);
temp1.Format("\t(HelpContext: %s\n)" , pErr->HelpContext);
AfxMessageBox(temp1);
}
}
}
catch(_com_error &e)
{
PrintComError(e);
}
}
void PrintComError(_com_error &e)
{
_bstr_t bstrSource(e.Source());
_bstr_t bstrDescription(e.Description());
AfxMessageBox("Error\n");
CString temp;
temp.Format("\tCode = %08lx\n", e.Error());
AfxMessageBox(temp);
temp.Format("\tCode meaning = %s", e.ErrorMessage());
AfxMessageBox(temp);
temp.Format("\tSource = %s\n", (LPCSTR) bstrSource);
AfxMessageBox(temp);
temp.Format("\tDescription = %s\n", (LPCSTR) bstrDescription);
AfxMessageBox(temp);
}
