• Sureshpr VS Setup project with Windows Service

  I have a Setup package including a Windows Service component. Service installation is handled through an installer (plain .exe without Installer class) that is set as a custom action under the folder "Install" to the Setup project. When installing, things go well. However, when uninstalling the package, I need to remove the service. Previously, I added a similar custom action under the folder "uninstall" and I had thought that it did get called when the package is removed, but I was wrong - the custom action under the folder "uninstall" does not get called when the package is removed. Is there a way to set the Setup project so that an executable gets called when the package is removed Thanks for any ...Show All

• The Admiral Adding a check box to a datagrid

  Hi, Can anyone help me in adding a check box to a grid view. I have searched in google and had a few sites that show how to add the checkbox, but the procedure is quite confusing.

• Keyu Basic WinForms question

  I am new here. Can anyone tell me why many people are saying WinForrm App is a smart client What make WinForms smart Thanks Hi, Smart client in the sense means the entire processing of data happens in the client, unless you do not Remote your components. In case of Web UI we call them as dumb clients since the entire processing is done at the Web Server. -Ajeeth It answers my question. So, WinForms is between thin and fat client :-) Thanks I think you are misunderstanding the meaning of a Smart Client Application. Maybe not, but read this article, which is an introduction on Smart Client Applications. https://www.microsoft.com/ne ...Show All

• luca82 Typed DataSet's with Large Amounts of Data

  Is there any documented maximum number of tables, relations, or records in a typed DataSet object in .Net 2.0 I have a large DataSet (the select command returns 24 result sets with tens of thousands of records total (approximately 90K records of varying sizes.)) If I fill from a DataAdapter into an untyped DataSet, the fill operation returns in just over 1 minute (approximately the time of the select procedure.) If I then merge this untyped DataSet into my typed data set (after calling BeginLoadData on each table) with constraints turned off (EnforceConstraints = false) the merge takes approximately 20 minutes. If I then enable constraints, the program runs for slightly over 20 minutes, and returns an Out of Memory exception. I expec ...Show All

• Sean McLellan Make sure you are not dividing by zero.

  I am getting this message at this statement: g . DrawLine ( p , xPos + offset , yPos1 , xPos + offset , yPos2 ); g is an instance of the Graphics Class. It is not my code. I am trying to adapt NPlot package to my main application. The whole thing works well when NPlot uses an XML file (DataSet) that comes with NPlot. I copied the schema to another file and input my own data into the dataset and this error sprang up. I do not understand what the difference really is since I tried to copy everything slavishly. There are no dividions in the set of parameters. I cannot figure out why this message is appearing. Thanks. Glad to hear you found it.

• jtallard First VB trial and no joy

  Hi I have developed a number of ASP applications, and also quite a few Access-VBA apps. I had a need to monitor some Access applications that run unattended, so I decided to take the plunge (from VBA to VB) and to try to write a VB.Net app with VS2005. That proved to be a torturous move, as nothing seems to work, and I am getting nowhere whatever I try. I created a project, added a form, then had to look all over the place to find out how I could simply access my Access DB and launch a SELECT statement on one of the table. But whatever I do, and even before I get to the connection to the Access DB, i ALWAYS get the same error, which tells me absolutely nothing: " A first chance exception of type 'System.ArgumentException' occ ...Show All

• Blast How to automatically resize toolstripcombobox when form is resized?

  Hi! I have a combo box on a toolstrip - toolstripcombobox - how can I automatically resize the combobox when the form is resized Matt One way of doing it would be to add an event handler into the Form's Resize event. At that stage you know that you are resizing the Form so you need to resize the combobox too. Jero This should do it: protected override void OnResize(EventArgs e) {  base.OnResize(e);  ToolStripComboBox1.Width = this.Width / 2; } Put that in your Form.   Edit: Sorry I forgot to give a description. When the Form is reasized for any reason, it will call the Resize event which will get into the function above. The code above thensets the wid ...Show All
