• SQL Server Expand/Collapse all in a report

  Hello. Is there a built in option of adding an Expand/Collapse all Button to my report I have a report with few groups and I want to give the user a simple way to expand all of them for easy view or collapse all of them so he can see only the groups header. I thought about using an expression in the hidden property of the groups and try to control it with parameters but its looks like a lot of work. Is there something "of the self" for it Thank. Roy. I thought about starting to build some button for this thing but I predict problem with it if I'll try to sort the table and the page will refresh it self every time. Did any body tried this before Thanks ...Show All

• Visual Basic Not able to save data to database

  I am thinking that this is actually a very easy issue, but I can not figure it out and am hoping someone can help me. I have a database setup with no data yet. I am able to connect to it and everything fine through Visual Studio/VB 2005. I built a Windows form that I want to use to Add records to a table. I followed examples from books on doing this by taking the "Data Sources" table and dragging it onto the form. When I run the the project, the form comes up with the add record button active. I click that and add data, skipping over the auto-increment field. The Save Data icon never becomes active and if I click on the Add New icon again, I get an error about the auto-increment field not being allowed to be null. When I ...Show All

• .NET Development Proxy Setup in Socket?

  Dear All, How can I code the proxy setting when using System.Net.Sockets.Socket to connect ftp server instead of using FtpWebRequest Thx a lot. You can't. If you want to connect using Sockets and do FTP, you need to connect to the proxy first and then do the ftp. Depdning on how this is done, you have to tunnel the requests through http. In short you can't ...Show All

• Software Development for Windows Vista XPS and StartDoc

  I was trying my application on the latest Beta 2 release of Vista and found some weird features when writing out to XPS. In my application the user has the option of going into a print layout window. This layout window allows the user to place the desired application related objects on pages for printing. When the user goes into the dialog, I go create a printerDC based on the default printer and hang on to that DC until the user closes the layout window or changes to a different printer. While in this dialog, the user can change how the objects are layed out and print at any time. Inside I call startDoc with just the application name and when saving to an XPS the first time, the XPS file is generated successfully. If I write to a di ...Show All

• Windows Forms A challenge. Text to binary, and back.

  In my windows forms application I need to develop a method to convert a string to binary and then back again. This is going to be a simple way of user authentication to secure the data. Aside from that conversion I will be doing another conversion with it to secure it even further. The only part I need to know how to do is the binary to text and back. Here's my logic: User inputs password -> Converts to binary -> my conversion -> finalized password User retrieves password -> my conversion -> converts to string -> original password no worries. I can't think of a way to get those byte[] values written to disk back into "real" byte values rather then for it to interpret them as something else. Do you have to ...Show All

• Visual Studio Bug in Batch Build in VS 2005

  I often use the Batch Build form to do a release build, without having to change the currently selected default build from debug to release then back again. But when I examine the calls issued to csc.exe (in the Output window) it specifies the references to the debug assemblies, e.g.: csc.exe {some params}/reference:C:\Projects\MyProj\bin\Debug\MyProj.dll {more params} Usually it wouldn't matter much, assuming the content of the debug and release builds are similar. But I allow the assembly versions to autogenerate, in AssemblyInfo.cs: [assembly: AssemblyVersion("1.0.*")] Therefore the version sometimes differs between debug and release. I can still run the app, so far so good. But then I obfuscate using Dotfuscator (community ed ...Show All

• Visual Studio Team System Support for Oracle and DB2?

  Hi, Do you have any plan to support Oracle and DB2 Or is there any extension point to write plugins for other databases Thanks. Makes sense.

• Windows Forms Control coordinate offsets?

  Can anyone enlighten me as to why the x-y coordinates get messed up when you put controls in a panel I inserted a panel on my form and set it's location at Point (12, 131). This put it below my dataGridView control, which is at Location Point( 12, 12 ). Then I put several textboxes on the panel and the y coordinates for the textboxes are all off by approximately 100 pixels. For example; I inserted a textbox in the upper left corner of the panel which should have set the location point (based on the x-y coordinate of the panel) at Point (77, 140), but the Location property is Point ( 77, 14) which should put the textbox nerw the top of the form under the dataGridView component; however, the textbox displays in the correct Location in ...Show All

• Visual Studio Team System What is the DropLocation really supposed to be?

  At first I thought that the drop location was a way to drop a built application to a live deployment location. This would be great for web apps that need to be pushed out to QA, Staging, Etc after being built. After working with Team build I see that it really is just a way to create a versioned history/backup of the built binaries. I dont really see any value in requiring that the drop path be a unc share. Wouldn't most people store the history on the build server itself Could someone please explain to me why the drop location must be a UNC share What if I dont want to create a versioned drop I work in a dynamic environment and we follow a branch by feature strategy. If a feature is built and deployed to QA, I dont really need a back ...Show All
