• Visual Studio Team System Handling pre events to perfrom validation

  hi all, We are successfully utilizing TFS event subscription via webservice and doing tasks like work item generation, email notification etc but the problem is we cant do any validation as they are post events, is there any legal way of handling pre events so that we can perform our validations or anyway of rollback, plz advise.. regards faraz Faraz, there is no functionality in v1 to provide additional validation through a webservice. You could do the validation in UI by building a package, but that is only for UI and those validations could be bypassed by using OM or by not installing your validation package. I can give more details on building such package if you are interested in this option. Anoth ...Show All

• Visual Studio Team System Cannot pass a GCHandle across AppDomains

  While working on my Automaton framework for build automaton with Team Foundation Server I've come upon this rather cryptic exception. It seems to happen only once in a while, something I'm able to do successfull requests without this exception. What I have is an .ashx which returns some HTML content to my .aspx, and the .ashx is called using Xml Http javascript call (AJAX).

  Hello folks! I have installed SQL Server 2005 Express and SQL Server Management Studio Express.

• Visual C++ symbol IDR_TOOLBAR1 undefined.

  Hi, I am creating a win32 application with Dialog , i want to create a docable toolbar in that dialog, when i inserted a new resource (Toolbar) named IDR_TOOLBAR1 and using it in source file, resource.h file already included, yet it doesn't recognise IDR_TOOLBAR1, when i find the definition for the same from context meny, it gives a message 'symbol IDR_TOOLBAR1 undefined', but it is there in resource.h. If code for implementing the Docable toolbar in dialog in win32 application, that will be very helpfull for me. Any help will be appreciated. I think you might have renamed that control after adding it. most probably the error will be coming from DoDataExchange function where the controls get binded. Even you rename the s ...Show All

• Visual C# Metafile serialization impossible ?

• Visual C# Read 1 byte at a time from an array

  Hello All I'm still converting onto C# from COBOL and have managed to read a file of bytes into an array using the following; byte [] allBytes = File .ReadAllBytes(openFileDialog1.FileName); I'd now like to loop through the array, one byte at a time and check that byte to see if it contains binary zeroes. Any suggestions as to how I could do this If they are zeroes, I'd then like to jump 200 bytes forward and see if this bytes is also zeroes then take some action ! Thanks Mark Many thanks - it's great to see code and how it works, very different to what I'm used to. Once inside the for loop, how do I actually check an individual byte In COBOL it would be something like allBytes(i) but I ...Show All

• Visual C# Capturing the up/down arrow key in a child form

  Hi, Recently, I was trying to capture the UP arrow key from my window forms application. I was able to capture the key in the parent form but once i open a child form, I would not be able to capture all the arrow keys but the rest of the keys like 'a', 'b','+' and etc are ok. I have searched the web but did not find any solution. Does anyone know how to overcome this problem Thank you. Soh GavH is correct. You should avoid using KeyPress or KeyDown event because will produce some Debuging problems and will not catch some special keys. ProcessCmdKey is a right way to do it. ...Show All

• Windows Forms location of image inside a picture box?

  hi, is there an easy way to determine the location of an image inside a PictureBox control i have a large image inside and the SizeMode is set to Zoom (to maintain aspect ratio) so there can be either a visible margin to the left and right or to the top and bottom of the PictureBox control. i think i can do this by knowing the aspect ratio of the image and the aspect ratio of the PictureBox but i am really lazy and don't want to do the math. i was thinking there would be some sort of magic image location property but i can't seem to find that. it seems that it must be known at some time since OnPaint() knows where to paint the image. thanks, scott thanks, i've done the math. it was not really that bad but ...Show All

• Visual Studio Express Editions VB Express adds junk characters to txt files
