• Windows Forms How to do a discrete update of a dataset

  I'm sure there are MANY ways of doing a "behind-the-scenes" update of the data in dataset, you know an update that happens to the data in the dataset but the user doesn't see he/her datagrid change much if any. I have an idea about how I CAN do it but I am wondering how I SHOULD do it. I'm sure there is a best-practices article out there somewhere but I can't find it. Has anyone found a a really great way that has worked for them, for multiple users Anybody have any ideas I am a VB/C# .NET 2003 programmer using SQL Server 2000 databases, but I'm open to other languages and/or database architectures.   - Thanks in advace for any and all ...Show All

• Windows Forms Losing events in MDI forms (1.0 vs 1.1 framework difference)

  I have an MDI parent form with two mdi children.  Each MDI child has two textboxes on it.    On version 1.0 of the framework, if you switch from one form to the other and then tab to the next textbox, a 'LEAVE' event is raised.  This works as expected.  If you take the code and run it on 1.1, the leave event do&n ...Show All

• Visual Basic Creating totals from imported data

  Hi, I have an access database linked to a data control and the relevant record source(s) called via SQL. Currently the data is output to a picture box and is selectable by date. What I am looking for is to select a range of items (all sales on the same date, all sales within a range of dates, that of monday through sundays date and also monthly) and show the total amounts for printing. (Sorry I'm having trouble thinking how to explain this!) Bump - Have made the addition of selections of sample code from my project which still seems unable to select from nominated criteria.

• Windows Forms Web Services as datasources

  Hi,    First of all, congratulations on a great release for beta2, it feels like a Ferrari when you've been working in beta1 for months.    I really love the databinding story for windows forms against direct database access (sqlclient), from the RAD level to the "low level" implementation of typed datasets/tableadapters.    Will there be a similar story for webservices I've already implemented a framework where all you need to do is drop a webservice component in the winforms designer and then attach it to a "Controller" component on the same form setting its "WebService" property, and ...Show All

• Visual C# Process.Start problem

  Hi, all. I am helping a friend do his VB project which is similar to CS. He is supposed to send a command to DOS which then outputs that command to a controller of his robot for activating its movements. Lets say the command he sends to the DOS robot is fixed at "run start trial1". Then, in order to execute the functions above, I did the following code in CS: private void button4_Click(object sender, System.EventArgs e) { Process.Start("cmd.exe","/C run start trial1"); } The above process.start method has worked for other examples i tried, example "edit". However, when i used "/C run st ...Show All

• Software Development for Windows Vista When designing WF by xoml-only file, we can have a VS-generated code-beside.

  Hi, I just made a workflow console app project (using Beta2.0) and deleted default .cs files and add a single .xoml file (just add a text file and change its extension to .xoml). So, assume this is a xoml-only (test.xoml) and I just simply added a code activity to the workflow by coding xoml like this. <SequentialWorkflowActivity x:Class="test.Workflow1" x:Name="Workflow1" xmlns:x=" http://schemas.microsoft.com/winfx/2006/xaml " xmlns=" http://schemas.microsoft.com/winfx/2006/xaml/workflow "> <CodeActivity x:Name="codeActivity"/> </SequentialWorkflowActivity> Now I ...Show All
