• Windows Forms Testing Multiple Instances of Winform application

  Hi, Wanted to know what are the testing tools available to test the multiple instances of a win form application. Here is what i need to do: I have a win form application which uses some external toolkit. the toolkit has limitations in terms of the instances creation. I wish to automate the stress testing of the win form application using some tool so that i can find out the threshold limit of the external toolkit.. Basically i want to do a load generation on the win form app by spawning multiple instances of the application with the necessary user clicks scripted in. Are there any tools that come along with the VS 2005 which can help me or i have to resort to LoadRunner or any other tool. Any pointers would be appreciated. Thanks Paritos ...Show All

• Windows Forms Problem with editing cells in dataGridView

  I have the dataGridView control with a checkBox type column. When i click on that column, there is no state change on it. Visible state is changing, check box is checked but from the code it has old value. That cell change its state when i move the cursor to the row abowe or below.

• Software Development for Windows Vista SQL 2005 issue revisited

  I am running Vista Beta 2 and 6 months ago I tried to install SQL 2005 developer edition. The problem I had was that I could never get a good enough install of SQL 2005 to even run it in order to get SP2. I would am going to address this problem again however I was wondering if there is common knowledge of this problem as I have described it so far. I can provide more information once I start the install again but I wanted to review as much as I can before starting that process. The only thing that might be a new known factor for me is the 32bit vs 64bit. I just learned why flash has never worked on my Vista machine, it’s because flash is not supported on the 64bit IE so I wonder if this is the same with the 64bit version of SQL 200 ...Show All

• Visual C++ linker cache?

  When compiling a project does the linker cache what librarys it found certian object in If so how do I reset this, I can not seem to get the linker to stop looking for a library that no longer exists. There's an .ilk file in your Debug folder to support incremental linking. That's probably not it though. Check your Additional Dependencies settings (Linker, Input). You might also have compiled a source code file that contained a #pragma comment(lib, "blabla.lib") statement. Or you're linking a .lib file that has such a reference. If you can't figure it out, you can always use the undocumented /DISALLOWLIB:blabla.lib command line option... ...Show All

• SQL Server "Allow InProcess" provider option - Is it only for 64-bit Windows OS?

  Our linked server to Oracle is having the following error: Error 7302: Could not create an instance of OLE DB provider 'MSDAORA' Our database is SQL Server 2005 running on Windows Server 2003 (32-bit). The linked server uses Microsoft OleDB Provider for Oracle and the Oracle driver is Oracle 73 Ver 2.5. I have two question: 1. It appears our Oracle client is rather out-dated, could that be the cause of the problem if it's trying to run out-of-process 2. According to http://support.microsoft.com/default.aspx/kb/280106, setting "Allow InProcess" fixes it.. *Method 2 Set the Allow InProcess option directly through SQL Server Enterprise Manager when you add a new linked server.

• Smart Device Development IPv6 :: ICMPv6 :: Neighbor Discovery -> SOCKET implementation?

  Hello, Due to the fact that IPv6 offers now a lot of new features under the topic of 'Neightbor discovery' (rfc 2461) there are some challenges to use these new features to support the mobility for a smartphone (rfc 4068) . To do this there is the need to send ICMPv6 Messages. But up to now I haven't found a functionality of winsock2.h which seems to support ICMPv6 Messages. Has anybody an idea if there is a possibility to send and receive ICMPv6 messages with WinCE 5.0 (eMbedded C++) Or in other words: Could I change/manipulate the 'next Header'-Byte of an IPv6 Header and the 'next Header' itself If this is not possible, is there a way to implement your own socket for WinCE Are there some helping links Thanx for any help, Lucia ...Show All

• SQL Server Data Flow Task - Conditions to add value for a field.

  Hi: I have a data flow task in which i have multiple OLEDB sources going to a one OLEDB destination via UNION component. I also have a derived column component sitting behind the union, because there are some columns, which exist in the destination table, but are not coming from source, but I am responsible of providing values for those fields. The question is that some of those values are conditional, for eg. Lets say we have a column called RecStatusCode in the derived column component. The value for that column depends on a condition/criteria, so I need to query a db and based on the value of another field, I set the value of the recstatus code. How do i accomplish that I am thinking expressions, but I need clear direction in steps i ...Show All
