• Visual Studio Express Editions Options page with TreeView control

  I don't mean to rant, but for the past nine hours I have tried everything I can think of to create an Options page with a TreeView control, and I still can't figure it out. My goal is create an Options dialog with a layout very similar to the one is VB 2005 Express Edition. I've searched through IntelliSense an insane number of times to see if I can find something useful. And with no luck, I'm afraid. I can create the TreeView control, but the "dynamic" controls are what's giving me trouble. Simply put, how can I display X number of options on the right side of dialog when a certain node is selected, and then display a totally different set of options when selecting another node I was thinking of creating a load of User Controls, ...Show All

• SQL Server Merge synchronization does not synchronize the data

  Hi! I've the following replication topology: SrvA (Publisher/Distributor) -> (Transactional Publication/Push Synchronization) -> SrvB (Subscriber, Publisher/Distributor) -> (Merge Publication/Pull Synchronization via HTTPS for remote clients) -> Client (Anonymous Subscriber) To test synchronization with this tier I do the following: 1. Update data on SrvA 2. Push changes to SrvB (there are transactions that replicated) 3. Run RMO Merge Agent (.NET application) on Client and get messsage "No data needed to be merged", although there were changes made on publisher SrvA and SrvB I saw the thread where similar problem have been discussed ( http://forums.microsoft.com/TechNet/ShowPost.aspx PostID=664153&a ...Show All

• Visual Studio Tools for Office Filling a ListObject is really slow.

  Hi there, I've a listobject that I've bound to an array of objects, each class of the object has about 7 members. When this array has about 1000 elements (1000 rows in the listobject) it takes over 10 seconds to fill it and display it. This array is created from a webservice call so it'll take about 5+ seconds to retrieve the data so another 10 to get it on the screen is far too long a time. I used this technique below to see if manual 'painting' of the cells would be any quicker, for ( int i = 0; i < ds.Length; i++) { (Application.get_Range((Excel. Range ) this .Cells[i + 1, 1], (Excel. Range ) this .Cells[i + 1, 7])).Value2 = new object [7] {ds[ i].company, ds[ i].station, ds[ i].unit, ds[ i].fuel, ds[ ...Show All

• Smart Device Development Application installation error

  Hello, I am using VB.Net 2005 to build applications for a Dell Axim X51v (Windows Mobile 5.0). This is not my first program written for this PPC and all have built and installed fine, until now. I last built a CAB file for this app about 2 months ago to supply to a customer for pre-view. I have now made all requested changes and am attempting to build the CAB for the final version, but it will not install. When running the CAB on the PPC, it asks to choose the location to install the app, Then I see the progress bar and it progresses all the way to the end. It errors at the end with "Installation of MyApp was unsuccessful." and removes everything. There is no indication as to what the error was. If I watch the explorer wind ...Show All

• Visual C# keep in memory

  Hi, I need to keep in memory a value that the user would have enterred. i don't even know if it is possible Can you help me First of all keep in mind, When applicaiton is closed all memory it used is gone. So you cannot keep a reference of that (Atleast not in the modern Languages). The best thing you can do is ofcourse would be the use of Client Settings of .Net. Simply create a new key put a value in it and go... You can also add your own Custom types in Client Setting. To do it, Double Click Settings.setting under Properties in Solution Explorer I hope you will get what to do next. When a Key is created simply from your code you can access that in read/write mode using: glob ...Show All

• Visual Studio Team System Can I record memory usage with my load tests?

  Hi, This may be a silly beginner's question, but I am just starting to deal with load tests and can't find this information. I need to measure memory usage using my load tests. I can't find how to do that. The only things that seem to be recorded in the load test results are request and response times. Is there any way to measure memory usage using the VS2005 load tests And if yes, what am I missing How do I configure my load tests to record memory usage Thank you in advance. It may mean you don't have access to measure the perf counters on the server. If you're running the tests locally (not on a controller), make sure your account has access to the server. Once you're sure you have acces ...Show All

• Visual Studio Is it possible to use PrintPreviewControl to see preview of ReportViewer?

  Hi, I want to use print preview control to see the preview of the report rendered by RevportViewer control. Is it possible to do so Thanks in advance. Vijay You can generate EMF files from the control and use them in the PrintPreviewControl class. MSDN has a quick sample on using the PrintPreviewControl at http://windowssdk.msdn.microsoft.com/en-us/library/system.windows.forms.printpreviewcontrol.aspx . Instead of calling e.Graphics.DrawString() as that sample does, you would render out each EMF file (for each page of the report). There are some samples the demonstrate how to programmatically get EMF files from the ReportViewer control at www.gotreportviewer.com . Take a look at the "Print fro ...Show All

• .NET Development TcpListener getting 10042 error code

• Software Development for Windows Vista when exactly the WorkflowPersistenceService.SaveWorkflowInstanceState method invoked?

• .NET Development Invoking A webservice dynamically without adding a webreference!

• Software Development for Windows Vista Unpleasant surprise after installing Visual Studio SP1

  Dear all, Beware of installing Visual Studio SP1 if you have Workflow Foundation Extensions for Visual Studio installed. Everything looks ok until you try to create a new workflow. At this point, the binding of activity properties to dependency properties refuses to work. None of the dependency properties appear as valid choices for binding to. Also, the workflow snippets no longer work. There is a simple solution to these woes: Run the Visual Studio 2005 Extensions for Windows Workflow Foundation setup program and Repair your installation. This is not mentioned anywhere in the VS2005 SP1 release notes. Dear Kushal, I'm glad you can reproduce the issue with the workflow snippets. Having created a new Sequentia ...Show All
