In OnCreate(LPCREATESTRUCT lpCreateStruct) of my View Class I put the timer and create the Static Text
     

  CStatic *pStatic=new CStatic;
        pStatic->Create(_T(""),WS_CHILD|WS_VISIBLE|SS_CENTER,CRect(10,1,150,50),this,IDC_STATIC_TEXT);

      //---------------- für Datum / KW / Zeit ---------------
      SetTimer(1,1000,NULL);  // siehe OnTimer
      //------------------------------------------------------




In OnTimer(UINT nIDEvent) I wrote the following :


     CTime time=CTime::GetCurrentTime();
     m_str_Zeit  = time.Format("%H:%M:%S  ");
     m_str_Datum = time.Format("%d.%m.%Y  KW:");
     m_str_KW    = time.Format("%U");

   
        GetDlgItem(IDC_STATIC_TEXT)->SetWindowText(m_str_Zeit+m_str_Datum+m_str_KW);
       CRect rect;
       GetDlgItem(IDC_STATIC_TEXT)->GetWindowRect(&rect);
       ScreenToClient(&rect);
       InvalidateRect(&rect);
       UpdateWindow();



      

In OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) I did the following:
{
      HBRUSH hbr = CView::OnCtlColor(pDC, pWnd, nCtlColor);

      if(pWnd->GetDlgCtrlID()==IDC_STATIC_TEXT)
      {
            pDC->SetBkMode(TRANSPARENT);
            return reinterpret_cast<HBRUSH>(::GetStockObject(NULL_PEN));
            
      }
      else
      {
            return hbr;
      }


}

The problem:  I would like to show the user the date and time (time running) . I have the transparent text but you see a rectangle in white blinking. How can I fix this?

Dell Optiplex 7020, Windows 7 Pro SP1, 64 Bit

I am unable to install the .NET framework.
Windows had become damaged, so I restored it from a previous image backup.
Everything worked fine after the backup except for the .NET framework.

I have downloaded the 4.7.1  stand-alone, but the installer stops with errors.  Same happened with 4.6.2
I used IOBit Uninstaller (free) and removed all the .NET components that could be found there.
I tried to turn off .NET  3 using the Windows features uninstall, but that gave me errors as well.
Features uninstall error
I ran CCleaner Free, did all the registry repairs.  I ran twice because the .NET issues weren't cleaned up after the first run.

I have included the simple Installation log below
Thanks

When building code, I am not seeing my changes.  I've changed a simple Text Header on a page and ran the code and it does not change.
I've cleared my cache, restarted, tried a clean build and am at a loss as to what cold be causing this.

We have tested and this is only happening on React JSX pages.  It doesn't look like Webpack is compiling the changes but rather old code.

Hi Experts,

I am trying to debug my vb.net program.

How can I determine what database is being used by a Data Grid View (dgv) control in run time?

My Data Grid View (dgv) control is dgvMaterials.

This works just fine. I can open my sql table Customer and add some new data, but only one row.


But I would like to use an sql query like this:

("SELECT * FROM '%s'  WHERE Order_No='%s'",Table1,(LPCTSTR)str_Order_No)
so I would like to find all rows of my Table “Customer” with Order_No = str_Order_No and change all of these rows with new
data.

I do not know where and how to put the query and change the code?

Please let me know, thank you very much.
Best regards,

Hi Experts,

I don't get this error when I run my code on my PC, either inside or outside the IDE.

I have created an installer to run in a clean Windows 7 setup on a Virtual PC.

But when I run the .exe in the Windows 7 setup I get this error:

Object reference not set to an instance of an object

No other information about the error is given.

How can I debug the error (without using lots of tracing information)?
Is there any way of configuring my code to output information about the error?

Regards,
Leigh

SQL Server 2000
First I did this:
CString  str_CustomerNo_from="1000"
CString str_CustomerNo_to      ="4000"

sql.Format("SELECT * INTO Sicherung_Thomas.dbo.Customer FROM OMSDaten.dbo.Customer WHERE CustomerNo>='%s' AND CustomerNo<='%s'ORDER BY CustomerNo ASC",str_CustomerNo_from, str_CustomerNo_to);



Then I deleted the data that I saved before:(in OMSDaten database)
sql.Format("DELETE Customer FROM Customer WHERE CustomerNo>='%s' AND CustomerNo<='%s'",str_CustomerNo_from,str_CustomerNo_to);


Now my question: How can I copy the data back from Sicherung_Thomas.dbo.Customer to the existing table OMSDaten.dbo.Customer?
                                             I can not use SELECT * INTO because the table already exist.

Please let me know.
Thank you.

I have been able to create a CRecordSet object in MFC to query a database table. Is there a better alteranitive to using CRecordset? to run queries against sql server?

CRecordset is derived from CDatabase, so I don't know iif somehow possible to just use the CDatabase class instead. They are both ODBC.


Should I stay away from ODBC, and use something else to connect from C++ MFC to sql server?
