• Windows Forms Pass Path to OpenFileDialog

  Is there a way to pass a path to the OpenFileDialog everytime the dialog is shown I tried the InitialDirectory but that works the first time (obviously) but if I change the path, the open dialog goes back to the last opened directory. Thanks, Greg I tried that and I don't see any difference since it just still opens the dialog back to the last opened position. I have a tree node with a list of vendors. Each vendor has a specific source path for their files. So when I go to the first vendor and open the dialog, it goes to the initialdirectory folder which is fine. However, if I go to another vendor who has a different path for the source, then when I open the dialog, it opens the dialog to the la ...Show All

• Visual C# Property Storage

  Is there a component or method to store for position and the size of a Windows Form and other controls Developer Express had a nice component that would allow you to store and retrieve this kind of info for any component, any property. Hi, yes, you can use property - Application Settings binding functionality. To make Visual Studio 2005 create the necessary binding code to load (and store) the form's position in user's configuration files, follow these steps: 1. Open Form's properties 2. Find (ApplicationSettings) and open it 3. Open Location item combo and select New 4. Enter the name of the setting (e.g. MyFormLocation) and click OK 5. On FormClosing event, save settings ( Properties. S ...Show All

• Visual Studio Tools for Office Adding a macro to excel using C# in asp.net

  I am creating a customized excel report for my company using a webpage. Part of the excel file is a macro to handle printing though, and I can't seem to get it to work correctly. The code works... The page building the report impersonates a user that has access to Excel. Excel files can be created but, when I attempt to add the print macro I recieve this error: Programmatic access to Visual Basic Project is not trusted The user being impersonated has the security setting in excel set to: Trust access to Visual Basic Project I discovered on accident that if the impersonated user is actually logged in on the server that the code executes as expected, every time. If you have any idea how to correct this problem please let me ...Show All

• Software Development for Windows Vista Communication with external applications

  Hello, I've been trying the hands-on labs and now I'm developing a simple workflow myself, but I don't really know how to communicate between an external application and the local workflow. I know that lab05 deals with a similar topic but I've found that the communication was only between a LOCAL application and the workflow but not with an external application. Now I'm trying to follow the expense reporting application in lab01 (resources folder) and I try to see how it communicates with the workflow. I've seen it uses .NET Remoting to create an instance of the remote class, but I don't get to understand well what it does because the same project has together the remoteservices class and the localservices class.

• .NET Development ?? in regex

  Hi, while looking for a pattern to find repetitive patterns, e.g.: string = " 999 888 777 " should match "999 888 777" (note should not match the spaces following the last pattern) I tried the following ((\d)\2\2 * )+ expecting the * to minimize the match at the end but it does not work. Instead, I get 3 individual matches. Can anyone explain it Thanks Thanks for the reply. My question is more general, I should have made that clearer I guess. The pattern I showed was only an example. I am trying to understand why the \s* is not what I expect when used within a ()+ construct. The general pattern is this: ( ppp * )+ where ppp is ANY pattern (above it was (\d)\2\2 but it could b ...Show All

• Visual Studio Team System Does VSTS support Dynamic data binding ?

  I am facing the problem: How can I bind dynamically generated Product ID to form post parameter from db with condition that this productID was previuoslly generated by company XX Thanks Casik What you'd want to do is create a view in the database that puts all the data for a virtual user on a single row. Each row in the view would then represent a virtual user. Our databinding will pick a different row automatically for each virtual user. Alternatively, you could use standard ADO.NET to read directly from your database and grab the info you need right at the start of your tests. You could do this in a coded web test or by creating a WebTestPlugin. You could add all the data you need to th ...Show All

• .NET Development Clipboard object throwing exception on Web Server 2003

  I'm about at my wits end on this one - so any help would be much appreciated I've developed a web ASP.Net application under .Net version 1.1, tested it, and ran it on my WindowsXP Pro. laptop IIS 5.1 web server.  It runs fine.  The ASP.Net code behind pages call calls methods from a custom developed assembly (built to partition out functionality).  This assembly writes to and reads from the clipboard object.  Unfortunately interacting with the clipboard is a necessary evil at this conjuncture in the development cycle. Now when I moved the application to a Windows 2003 Web Server (via a .msi pulled together by a VS Deployment project) and execute the application I get the following exception mes ...Show All

• Windows Forms FormClosingEvent has no CloseReason

  In a Form I created, I've subscribed to the FormClosingEvent. In this event I want to distinguish between a user that closes the form, or an outside OS event that closes the application. Therefor I read the CloseReason member of the FormClosingEventArgs. However it seems that when the user clicks on the OK button which is the Forms AcceptButton, the CloseReason seems to be set to "None". The same goes for the form's CancelButton. Is this intended behaviour, and if not, should this not be documented it was something I thought more of as a workaround (now there are two "closing" state variables), but if it's the only way it'll have to do.
