• Visual Studio Express Editions How can you take a DropDownList selection to fill a GridView?

  I would think this would be pretty easy but I am new a C# programming. I am using Visual Web Developer Express (great program at a great price) for C# and I simply want to make a selection in a DropDownList and have the detailed information (from the database) come up in a GridView or DetailView on the same page. Any help would be much appreciated!! Thanks! Actually, I just figured it out. This will do it: OnSelectedIndexChanged = DropDownList1_SelectedIndexChanged ...Show All

• .NET Development Unmanaged code

  Hello, If I'm posting to the wrong forum please advise. Thanks. I have just started using visual studio .net 2003 (C++) and have created a windows form .net  application which I have put quite a bit of time into, but now have found that I am not able to include wininet.h without getting a bunch of compiler errors. Could someone give me a sample of a way around this problem by using dllimport, pinvoke or reflection, I have run across all of these methods through out my web searches but they were usually written in some other language other than c++. If you can give me general way to make wininet "InternetDial" to compile I wou ...Show All

• .NET Development Table adapter configuration wizard bug, Oracle 10g

  I have been having a problem with the table adapter configuration wizard in Visual Studio 2005.  When I try to configure a table adapter that includes 2 or more tables joined together, the designer reports the following error: Syntax Error: Expecting '.', identifier or quoted identifier. When I hit Ok and return to the dataset, the data table does no include my queries columns.  If I try to add the columns manually, I get a very similar error message from the designer. This only seems to occur with Oracle connections.  I'm using an Oracle 10g database/client.  Switching to SQL Server is not an option, I already tried. ...Show All

• Visual C# Why is the C# team allowing this to Happen? and Why do they close threads on the topic?

  Since PJ. van de Sande Closed the last thread I opened : Why is the C# team allowing this to happen I guess because he didn't click the link or he didn't like the topic.  I brought the link information here.....  So I ask again... Why is the C# team allowing this to happen   If he closes it again, please respond here From the Blog link: From Tom Archers blog Why so many examples in Visual Basic We find another thing for us to ignore from MS when trying to do what they do, and not what they say to do. This blog from Feb I wrote touches on the VB.NET & C# mess discussed in the threads ...Show All

• Windows Forms How to do indeterminate progress bar?

  Sometimes you know when a task begins, and when it ends, but you don't know the increments. In such situations you want to display an "indeterminate" progress bar, which basically means the progress bar doesn't fill from left to right, instead a few segments move from left to right and starts over from left, and this repeats. How do you do such a "never ending" progress bar I have seen it in Microsoft applications, but I don't see a property on the progressbar class to turn this mode on. i need help i want to know how to add the progress bar on my web browser i have built, i added the progress bar, i have ...Show All

• SQL Server SMO Method Performance

  I've run a series of performance tests on a test app that uses smo for creating sql server tables (including columns, indexes, triggers, and foreign keys) and stored procedures (including parameters). On a 2.7GHz machine with 512MB ram (both app and Sql Server running locally), the series of tests yielded the following results: Table.Create() 0.3 ==> 0.6 seconds PrimaryKeyIndex.Create() 0.7 ==> 0.9 seconds Trigger.Create() ~0.06 seconds StoredProcedure.Create() 0.12 ==> 0.14 seconds With creating a large number of tables/indexes/stored procedures in the app, I'm concerned about performance.

• SQL Server using sysdate date/time in bulk load to sql server

  Lets say, I have the following xml doc: <customer>     <name>xyz</xyz>     <name>xyz1</xyz>     .     . <customer> customer(id, name, lastModifieddate) I am doing a bulk load into SQL sever for the above table. Though 'lastModifiedDate' is nullable column, I would like to insert a system date/time at the time of inserting in to the table. How do I write a mapping schema that would let sql server determin the current date time. This is just the opposite of sql:is-constant / sql:mapped annotation. The mapping element / attribute doesn't exist in the ...Show All

• Software Development for Windows Vista Xaml-only workflows and customization

  I've got a question or two about the long-term plans for Xaml-only (markup-only, xoml) workflows. It seems that if you want to allow some level of end-user customization of workflows, you'll want to implement them in Xaml-only rather than using the code-only workflows. Then you can distribute a set of Xaml files with your app and load them at runtime to execute the workflows. You can even host the workflow designer and give your users a way to make changes to the Xaml in a controlled way. All of that sounds great. However, with the current way (January CTP) Xaml-only workflows are implemented, this doesn't really seem realistic. The main pro ...Show All

• Windows Forms TreeView in WinForms 2.0 dosen't update itself when nodes are added

  Hi everyone, Within a Winform application, a treeview is contained in a User Control and the User Control is then located within a splitview. When the UserControl added some nodes into the Treeview, the treeview is not displaying the added nodes, it just keep displaying the initial node added to it during initallisation. Tried variious method like TreeView.Invalidate() and TreeView.Update(). The code which adds nodes to the treeview is already surrounded by TreeView.BeginUpdate() and TreeView.EndUpdate(). it is still not displaying the new contents. However, if you ask it to display the number of nodes in the tree, the Nodes.Count ...Show All

  Has anyone been able to import the xmi export file this tool generates into any other tool I have tried pulling Visio Use case diagrams into XDE, Sparx 4.1, and now Sparx 6.0 with zero luck. Are there any plans to upgrade this add-in to export xmi 1.1, 1.2, etc The 1.0 version it exports is not support with the rest of the tools (XDE and Sparx) on the market I am currently using. Tad To address your questions: The main purpose of the tool was to provide a mechanism to export model data (from class diagrams) into an xml file which you can programmatically access.
