• Visual C# Mouse Wheel Won't Scroll

  I have a Microsoft Comfort Optical Mouse 3000 which works great with every application except Visual Studio 2005. I have to spin the mouse wheel at a very high rate to get any scrolling at all in VS2005. I have the latest Vista drivers installed. There are some known issues with the Microsoft Comfort Optical Mouse 3000 in Windows Vista, an unofficial workaround you can try is the following: Install the Vista IntelliPoint software: http://www.microsoft.com/hardware/windowsvista/support/intellipoint.mspx or Click on the Start Button Start typing Device Manager Open Device Manager Disable the HID Compliant Consumer Control Device ...Show All

• Visual Basic Exceptioon error when trying to set ComboBox.SelectedIndex

  Hello All, First, just so you know, I am not a real programmer and have never programmed in visual anything before and am playing with VB 2005 Express Edition. In the Sub below I am simply trying to change PtComboBox.SelectedIndex when the RunComboBox selection is changed, but am getting the exception error shown in the comments in the sub. In the Form1_Load event handler I have this line. PtComboBox.SelectedIndex = My .Settings.PreTrig and it seems to work fine. I can change the value of My.settings.PreTrig and the box is set properly. There are 4 items in PtComboBox and there are only 2 items in RunComboBox. I sure hope someone can show me what I'm missing here because this makes no sense. Private Sub RunC ...Show All

• SQL Server Replication Monitor Question

  Hello, We have some mobile devices that are setup to replicate with our sql 2005 server via web sync. It seems that the devices are added multiple times within replication monitor. Is there a way to purge the bogus items. For example we have a mobile unit labeled as Device12 we have it listed under the subscriptions 5x. I would like to purge four of them as they are not currently being the replicated one. Device12-A6EE69A0944 is the valid subscription Device12-EE44D1EF3E24 is an invalid one. Thanks in advance. John You may want to query table dbo.MSsubscriptions in the distribution database to see if it has those extra entries. I'm not saying it's safe to delete them, but I'm guessi ...Show All

• Visual Studio 2008 (Pre-release) Resize Elements inside the canvas

  Canvas contains some UIelements like rectange, ellipse, button etc. I would like to resize child elements, when the canvas is resized. I'm able to resize the Canvas using Adorner. Can someone suggest me the general approach to resize any element that located inside the canvas. for e.g <Canvas><Button>Test Button</Button></Canvas>. In this case Button element should be resized with respect to the canvas. Thanks in advance, Venu I think use of viewbos will be the best practice, you should use adorner to resize the viewbox only, every child element, will resize on its own. ...Show All

• SQL Server SQL Server vs. XML Configurations

  I have been experimenting with both XML and SQL Server Configurations. Management would really like to go with the SQL Server Configurations, but I seem to be having problems with them. The main goal is to be able to create a configuration for each connection and have every package refer to its specific configuration, therefore in the future we could change say our SA password and only have to update this in a few places rather than for every package. In order to experiment with the problem I am having I developed 2 identical packages, except one uses SQL Server Configurations and the other uses XML. The configurations save the exact same properties. With the XML package I can go into the configuration file and change say the passwor ...Show All

• Visual J# Help With FileSystemWatcher Please

  Hey all, I am having trouble with a FileSystemWatcher. It is not acknowledging changes in a file. I have the FileSystemWatcher's NotifyFilter set to Size in the properties menu.

• .NET Development Image File Execution Options

  Can I specify mdbg as the Debugger in HKLM/Microsoft/Windows NT/Current Version/Image File Execution Options/debugee_name and get the debugee to start with mdgb attached This is useful for debugging services when they start. Unfortunately, Managed-only debugging does not work with IFEO options. More details are here: http://blogs.msdn.com/jmstall/archive/2006/02/16/ifeo-managed-debugging.aspx Interop-debugging would work with IFEO, but Mdbg only has managed-only support.

• Visual Studio Print a report when it is hidden?

  How do you print a report/form when it's hidden I am using reportViewer and I don't know how to access the printButton. What I want to happen is someone clicks a button on one page, which calls the report page without the user knowing, and the report would automatically print, any printDialog. I know how to hide the form, just not how to have it print automatically. Any suggestions I figured since I figured this out I could share this information with anyone else who has this porblem. All you have to do is access the reportViewer_RenderingComplete event.. private void reportViewer1_RenderingComplete(object sender, Microsoft.Reporting.WinForms.RenderingCompleteEventArgs e) { this.reportV ...Show All
