printing - CPrintDialog Creation Failing in Service Mode of an Application -

-

I have an application that automatically prints the report. I'm using CPrintDialog to get printer DC I am 

  Zero CMyClass :: PrintReport () {CDC DC; CPrintDialog printDlg (FALSE); PrintDlg.GetDefaults (); :: DeleteDC (printDlg.m_pd.hDC); LPDEVMODE pDevMode = printDlg.GetDevMode (); if (pDevMode) {pDevMode- & gt; DmOrientation = DMORIENT_LANDSCAPE; :: GlobalUnlock (pDevMode); } HDC HDC; If ((hDC = printDlg.CreatePrinterDC ()) == NULL) {:: GlobalFree (printDlg.m_pd.hDevMode); :: GlobalFree (printDlg.m_pd.hDevNames); Return; } :: GlobalFree (printDlg.m_pd.hDevMode); :: GlobalFree (printDlg.m_pd.hDevNames); dc.Attach (HDC); // Attach a printer DC dc.m_bPrinting = TRUE; Dc.setMapMode (MM_LOENGLISH); / * Print Logic using DC * /}   
 This works fine when I run my application in debug mode, which comes with an AA console application.  
 However, CPRIIDO is the creation when I fail to run the application as a Windows service.  
 Am I doing something wrong? :( Please help me.  
 Note: The application is designed to run in the installation as a service.   
 
 
 
 CPrintDialog creation is failing when I Run the application as a Windows service.) In a Windows service. Therefore,  CPrintDialog  is never going to work.  
 But you do not need to create a dialogue to get printer device references, assuming that you already know what printer you want to print. And since you are running as a non-interactive service, you already know this because  should  already know this, because there is no way that the user can choose printer.  
 To do this, call directly, specify the name of device and printer for  "WINSPOOL" . By calculating the installed printer using the function, you can get the name of the desired printer. How is this easily documented for the article: / P>

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
