The goal is to get a 64 bit ODBC connection to an Oracle DB. I have to install Oracle Instantclient_11_2 on a fresh install of Windows Server 2012 nothing else. I am getting an error when trying to setup an 64 bit ODBC connection to a database not on this server but the DB is on a different one.  
In order to get Oracle Instantclient_11_2 installed I came across a message that said to install Microsoft Visual C++ 2005 Redistributable Package (x64)  in order to get it working. So I installed it from this link. MSVisualC++2005RedistibutablePackage
I do not know if that is conflicting with this process and I should get an application that is more recent to the Win Server 2012 ??? Does anyone know if I should or could be using a more recent that would not conflict with the Oracle_11_2?
I read and read and found this. So I understand some of it from this link. Side-By-SideConfigurationError
I looked at the event log and get the following.

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

  CStatic *pStatic=new CStatic;

      //---------------- 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:");

            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?

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.

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,

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

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

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

Please let me know, thank you very much.

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?

I  am  totally  confused when should I  use  OnPaint,OnDraw,OnCtlColor,OnEraseBkgnd,RedrawWindow
Will  you  please  explain me.When it  will  cause  flicker  and when it will  not?
What  is returning true or false  from Erase background function?
Can any one  brief me  please tomorrow I  have interview over  it.

Hi guys.

I'm using this code to read a text file locally and do the word search as needed but the problem is that the file which this app will be reading will be online on a web server and the problem is that the code I have now to read this text online I don't seem to figure out how I can split data so that I can still do word search just like how I do to a local file. Here is the code I use to read local file:

while(!in.eof() && getline(in, line, ','))
								if((offset = line.find(ID, 0)) == string::npos)
									id = atoi(line.c_str());
									in >> dat;
									getline(in, NUMBER, ',');
									getline(in, line, '\n');
									KEY = (int)atof(line.c_str());
									if(ID ==id)
										ID = id;
										//dst = dvs;
										va = KEY;

Open in new window

Now this code part is the essential part of code as its what I want to be able to do in the following code which is the code that reads a file from the web.

    #include "stdafx.h"
    using namespace System;
    using namespace System::IO;
    using namespace System::Net;
    using namespace System::Text::RegularExpressions;
    int main(void)
        Regex^ rxSubTitles = gcnew Regex("\\d.*>(?<subtitle>.*)<");
        String^ strFileIn = L"";
        WebClient^ wc = gcnew WebClient();
        StreamReader^ fileWebIn = gcnew StreamReader(wc->OpenRead(strFileIn));
        String^ strData = "";
            strData = fileWebIn->ReadLine();
                // take ONLY the subtitle without additional decoration
        return 0;

Open in new window

This code simply gets all the Titles.

Here is my text file structure:


Open in new window

As you can see each line has 3 data fields and

Open in new window

is the data separator and as you can also see that the 3rd field can sometimes be empty. I think if you can look at the structure and also look at my first code even though I didn't post the complete code on the first code but I think that s the main part which you may need as its also the main part I'm having problem with when trying to apply it to the second code.

I have 2 forms Form1 and Form2. Form1 is the core form or the main application first form which runs first then at some point it hide it self and show Form2, the problem now is that I want to also reshow back Form1 when Form2 closes.

Anyone know how I can have that. Currently the forms do hide form1 and show form2 but I can't include form1 on form2 because form1 has already had form2 included in it. I'm using Microsoft Visual Studio 2010 CLI application.

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.
