As far as I know, that is the general solution to such problem, and can be used in any language, since is supported by the OS through APIs. If CreateMutex() returns ERROR_ALREADY_EXISTS means there's an already running instance of your application.

Now increase the page footer height by 5 inch(since letter size paper height is 11 inch) & left incrasing area of page footer section empty. hope this helps one more thing .if you change your printer( by right click on report at design time) to dot matrix printer,then custom paper appear in print dialog box.

How to solve the problem? The detail information as below: 1) Window Console application (Call the Excel to generate a report as the Excel format) 2) CallBatch.aspx (create a process to run the window console application using the impersonate <identity impersonate="true" userid="<Domain">\<administrator user=""> Password= /> 3)Set the permission for the Excel DCOM component. -- modified at 5:58 Friday 6th July, 2007 Re: How to call a windows console application from the asp.net page Christian Graus5-Jul-07 23:29 Christian Graus 5-Jul-07 23:29  Why can't you just move the code from the console app into your code behind. You want to run this on the server, right ? Christian Graus - Microsoft MVP - C++ "I am working on a project that will convert a FORTRAN code to corresponding C++ code.I am not aware of FORTRAN syntax" ( spotted in the C++/CLI forum ) Re: How to call a windows console application from the asp.net page Terry.zhang10-Jul-07 17:32 Terry.zhang 10-Jul-07 17:32  Yes, we could move the code from the console app into the code behind; as your said, we need run it on the server as well. On the other hand, even if we move the code, the same permission problem still happens. Count Words Sinchan Nikam5-Jul-07 20:30 Sinchan Nikam 5-Jul-07 20:30  Hi all, Please help me ..

Please Help, Thanks. Benny Re: Using Listbox help TwoFaced5-Jul-07 17:21 TwoFaced 5-Jul-07 17:21  You'd write something like this text1.text = ListBox1.Items.Item(2).ToString() The array holding the items is zero based, which means the 3rd item is really the 2nd element in the array. Re: Using Listbox help benny777ex5-Jul-07 17:38 benny777ex 5-Jul-07 17:38  Thanks for reply just want make something clear, does the order of the item count from the top?? if yes, so the top one is 0, second one is 1, third is 2, fifth is 4? Re: Using Listbox help The ANZAC5-Jul-07 17:52 The ANZAC 5-Jul-07 17:52  that's correct. It's zero based indexing starting at the top. The last item will always be listbox1.items.count - 1. Remember the minus 1 when working with listboxes. You can also check if a listbox has any item selected through: if listbox1.selectedindex = -1 then<br /> 'none is selected<br /> end if Posted by The ANZAC : "WWBD, What Would Buffy Do?" : "I don't know man, she's stronger than me" Re: Using Listbox help benny777ex5-Jul-07 18:58 benny777ex 5-Jul-07 18:58  Thanks for your respond i have another question, I want to read the selected line with a text box, so I wrote: Display.Text = JobList.Items.Item(LineNumber.Text).ToString there are 2 textboxs: Display.Text, LineNumber.Text and 1 listbox: JobList but an error returned...
