• Visual Basic Printing - skip a page

  I'm using the PrintDocument's PrintPage event to do my printing. All works fine, but I can't figure out how NOT to print a page of a multi-page document. Even if I never call DrawString inside the PrintPage event for a particular page, a blank page is sent to the printer for that page. No. It's not the way PrintDocument works. It just calls PrintPage if you ask for another page with e.MorePages = true, it doesn't count pages at all... ...Show All

• Visual C# How to automatically close the parent form when the child closes.

  Hi, I have an application that uses 3 forms. Form1 contains 2 buttons - A and B. If you click Button A, then Form2 loads and Form1 is hidden. If you click Button B, then Form3 loads and Form1 is hidden. What I need to be able to do, is once Form2 has been completed by the user and then closes (by the user clicking the Finish button), for Form1 to close automatically, rather than unhiding the form and then the user having to click the button... I've searched quite a lot on how to do this, but can't find an answer. Either I'm searching for the wrong thing, or .... Could anyone provide any hints on how to do this Thanks. Andrej, yes, I'm using 1.1. I tried changing what you said but it now gives and error &q ...Show All

• Visual Studio Team System Is running Load Test without setting any Counter Useless?

  I am working with Load Test and am slightly confused. If I run a Load Test without setting any 'Counter Sets' would that be a useless test because I won’t have any set requirements to compare against If its not useless than how do I find out that the results which are generated have any value Or can I say that results are acceptable Additionally, many people use load tests to "condition" environments so that other types of testing can be done.  For example, you could use a load test to create 100,000 users on a test site that has recently been built out so that when you come in the next day you've got a realistic test bed to work against.   ...Show All

• SQL Server Quick question to check NULL values in input parameters in a stored procedure

  Hi: I have a stored procedure that calls 3 stored procedures. If some of my input parameters are NULL, I would like to skip the call to another stored procedure. Can you someone please help me with this I would like to find out what is NULL, before I execute the other stored procedures. Thanks so much. MA you could use coalesce since coalesce returns the first non null value examples declare @v varchar(40) declare @v2 int declare @v3 int select @v ='1',@v2 =3 if coalesce(@v,@v2,@v2,null) is null begin select 'is null' end else begin select 'is NOT null' end go declare @v varchar(40) declare @v2 int declare @v3 int --will be null if coalesce(@v,@v2,@v2,null) is null begin select 'is null' end else begin se ...Show All

• Visual Basic Setup Wizard in VB 2005 Standard SP1

  This one is aimed at Matthew Gertz in VB Development Team. Yes, I am aware that the Christmas Holidays are near but I hope your response will be quicker than last time. First two points and then my query 1. Despite ticking the Alert Me box, I am not getting Alerts when you post responses. 2.

• Visual C# Two FileWatchers watching the same folder...

  I have a windows app and a windows service ...both of them uses a file system watcher and watches the same folder. When I try to move files or delete files I get Access is denied how can I slove that without stopping the file watchers Thanks in advance Ala If I am not mistaken, the fileSystemWatcher does not lock a particular drive or file by itself. Just for the record: are you sure the denial is caused by the fileSystemWatcher and not another operation or program If you are not 100% sure, you can try a tool such as WhoLockMe to figure it out: http://www.dr-hoiby.com/WhoLockMe/ Or did you perhaps enabled a 'lock' somewhere else in the code ...Show All

• Visual C# Memory problem with String

  Hi All, Currently I am working on file operations. I have to read a file of any size and then replace the '\n', '\t' and other special characters with 0 and then assign them in a textbox. In this procedure memory uses is very good. But after all the calculation my last line is textbox.text = processedstring; but after executing this line memory use is almost triple the previous. So please anyone can help Thanks in advance. Sanjay How you are measuring memory usage With Task Manager probably. If so then never belive it because it never gives you right result. Use some other generic tool for memory measurement or use Memory Profiler for .Net Applications to find the exact values of memory allocation or deallocation. ...Show All
