• .NET Development Remoting between 32-bit and 64-bit processes?

  Will a remoting scenario work where one side of the conversation is a .NET 2.0 app compiled using the x64 platform and the other side is a .NET 2.0 app also running on the same x64 box, but compiled using AnyCPU and therefore running as a 32-bit process These are two separate apps, in case that's not clear. I'm just a beginner with using remoting, so no specific restrictions on protocols other than what would be necessary for same-machine communication. Thanks, Chuck OK, I just added the x86 configuration and ran there and it did run as a 32-bit process. Man, somewhere I got my wires crossed about what those configuration labels meant, but I think I'm on the same page now. So, will remoting work be ...Show All

• Visual Studio Tools for Office How to publish VSTO application to intranet

  Hi, We are struggling to find an approach to publishing a VSTO (Visual Studio Tools for Office) Excel application to the intranet. On the end user's browser we get the message "The customization assembly could not be found or could not be loaded". (On the browser on the intranet server, Excel and the application load correctly). Clearly, for a browser-based application, we cannot set the security policy on each end user's PC. We have followed various Microsoft walkthroughs, but none of them specifically address how to grant the appropriate trust for the document and the assembly to be accessible to the end user from the intranet. Is there a simple walkthrough that we could follow to publish a VSTO application (preferably Ex ...Show All

• .NET Development Multi-user problem with Access97

  I have developed a database linked to SQL server 2000 in access97. When I test the database on two of the three networks available to me, it will allow multi-users to connect. But on one of those networks (the one where the database is supposed to live) it will only allow one user at a time. The database is not set for exclusive use and the security settings in access appear normal. The folder in which the database resides is set for full access for use by a user group set up specifically for this database. This database was a standalone database which was accessible by more than one user. I re-created it so it could be linked to the SQL Server. I think it was originally done in access95 and converted to access97. When I changed it, ...Show All

• Visual Studio Express Editions Install VB Express application to All Users under Windows XP

  Is there a way to cause an application developed under Visual Basic Express to install for all users on an XP system I am logging onto an XP system, which many people use, as Administrator. I install my application, but when other users logon under their own ID they don't have it available. I also moved the Start Menu folder from my Documents and Settings folder to "All Users," which causes the program group to appear under all user's Start menu; however, the program itself isn't there if they try to use it (program group is empty). The Installer does not appear to have an option to install the program only for you or install for everyone. Any way to force the application to install for all users Thanks ...Show All

• Visual Studio Team System branching/merging for releases - am i doing this right?

  I've got a question about the right way to our structure and the branching and merging for releases. Here's the basic structure we have (simplified): MainProject Branch SomeTestBranch (not really relevant to this discussion) Release SubProject1 1.0 1.1 2.0 SubProject2 1.0 1.1 2.0 Trunk SubProject1 SubProject2 OK, so, we work off the trunk. WHen we have a release (say, 1.0 release) we branch it into the releases folder under the 1.0 heading. Great. Now we have a copy of what exactly was released. That's what i was going for. Now, we move on to working on 2.0 - so the trunk is being updated. In the middle of all of this, we find some pretty major bugs in the 1.0 release that need to ...Show All

• Software Development for Windows Vista Dynamic Delays help Please

  Hi i'm making a Task manager for clients. I am representing a time period by a Parallel activity and each task to do that time is a Listen with a HandleExternalEvent and a Delay. What i need to do is have the Delays to be "the rest of today" + some presubcribed window. I'm Creating the WF instance from a XAML file so i can easily edit the first time period using System.DateTime.Now and some simple math. But once the WorkFlow is Instantiated is there away so that once one time periods Tasks are complete the next set of delays will be the rest of that day plus their own timespan I was thinking of building a Custom Activity that Inherits from DelayActivity and making it's Execute method something like: Execute(){ ...Show All

• Visual Basic Invoke - trying to call a sub on a form from a separate thread

  frmMain has called a background thread to do work, this thread creates other threads to do work. From these threads I want to update a textbox with status updates (text) from those threads. I have tried setting up a delegate and using Invoke to pass the text back to a sub on frmMain, but it doesn't work. I need help. Thanks Here's what I changed and it still gives me the error: Invoke or BeginInvoke cannot be called on a control until the window handle has been created.

• Windows Forms Unsubscribing from all events

  Hi, I have a control and throughout my code I have multiple places where I subscribe to events e.g. MyEvents.SetNumberEvent += new MyEvents.SetNumberHandler(SetNumber); I'm having a problem that when some controls are disposed these subscriptions to events are not disposed with the control so when an event fires exceptions to do with the disposed control are thrown. Is there a way for me (in my HandleDestroyed method) to go through all the events I've subscribed to and unsubscribe from them rather than finding every event in my code and unsubscribing one-by-one myself Thanks in advance. Friendly Dog and RizwanSharp, I think you both missed my point - I know how to unsubscribe from an event but I wanted t ...Show All

• Visual Basic How to compare grapical (bitmap) data?

  I'm making this program for printable binary data. (that desn't matter now) But what does is how to compare that graphical data from a existing data base. This might give you the idea. You have seen how CSIs get a fingerprint, scan it(make it a piture) and then search AFIS, or another crime database That is what I'm trying to acheave. Please Dont let me down, on this! Or simply put, I'm trying to make a binary (bitmap)data comparing program. Of course after that data has been pocessed ( deleted all colors that would interrupt search, just the fingerprint color is there, nothing else). That should be perfect as I wrote it in VB Express. Are the lines exactly like this System.Runtime.InteropServices.Marshal.Copy(bmd1.Scan0, b1 ...Show All

• SQL Server Parallel execution of source SQL commands

  Hi, we're accessing a SQL Server as a source for some SSIS packages using quite complex SQL commands. We have dataflows getting data from up to 10 queries. The problem is that SSIS starts all these queries in parallel using up all the memory of the server (the source SQL server, not the server SSIS is running on). So the queries are very slow. Is there any way to force SSIS to start the queries after each other I already browsed the web for some answers on that and I'm not very optimistic... Maybe the only solution is really to feed the result of the query in raw files and process them later... Thanks, Hi Jamie, I hoped that there is a tweak for it... But that's what I expected... I voted for your suggestion and opened ...Show All

• .NET Development DataSet Merge Fails!!

  I have a problem with merging datasets. i have a typed dataset on the server side which is manipulated and i need to update a mirrored dataset on the client side. i use getchanges() on the typed dataset which returns a normal untyped dataset. i try to merge this returned dataset with the typed dataset on the client side but the merge fails! How can a merge fail when both datasets have exactly the same schema I also noticed that when getchanges() is called, the returned dataset contains rows from the parent tables which have not changed but whose child rows have changed. This makes sense and complies to what the getchanges() function claims to do. would this cause any problems in merging though i thought merge() works only on rows that do N ...Show All
