• shivali.sadavarte Need to abort uninstall based on user input

  Hi, I am creating an MSI using Visual Studio 2005, setup wizard. the install and uninstall are done silently. One of the uninstall custom action is to stop a service (using a VB script, i basically open up a shell and execute a net stop), the service name is given as parameter of the silent uninstall, i want to be able to abort the uninstall if the service name is invalid or null. Any suggestions Thanks Dinesh A cheesy way to do it is give the service name to a new watch process that kills the uninstall process if the service name is invalid. Since there is no commit it wont matter if the msi process die or not. A watcher process is a good way to get around msi limitations like not being able to run 2 ...Show All

• mkamka sorting a sortedlist

  Hi All, I have a problem in my windows application with C#.net. I have around 50 Id and Name pairs and need to sort them after putting into a SortedList. In my data, ID is not unique. SortedList< object key, object value> So I can't put ID in place of Key( Key must be unique in sortedlist). I have created a class with Id and Name variables, passing the object in place of value, and some integer index in place of key. Now the Question is, how to sort the SortedList on ID. Please me help out, Thanks. One of the constructors of the SortedList take a IComparer as an argument. You can use this to sort the list. Keep in mind if the icomparer returns a 0 you will get an error about adding a ...Show All

• FassaBortolo How can I make update version for application which was signed with certificate now expired?

  If I change expired code signing certificate to new one and publish updated application, client will fail to launch. And code signing fails if I try to use expired certificate. How can I make update version for application signed with old certificate So, I'm not sure exactly where the ClickOnce runtime team is on this issue, I know we've had a few discussions about it.

• UlliDK Creating my own TabPage class

  I have a tabcontrol on a form. If I add tab pages and add controls to them in Visual Studio the controls become members of the main form and the main form will also handle all events from all controls on all tab pages. I want to create my own TabPage class that handles everything that happens in the TabPage to avoid having all code in the main form. I created MyTabPage class by adding a new Component to the project and changing the base class to TabPage. I am able to drag stuff from the Toolbox onto my TabPage in Design mode. In the designer for the main form I added another tab page to the tab control and changed the type from TabPage to MyTabpage in the main form code. However, I am not able to see any controls in the tab when I ...Show All

• Escobar4Life Why isn't CellStyle Format preventing alpha characters in Number format column?

  Hi all, I'm a bit confused here. I set the CellStyle Format for each column in my datagridview to be: 1) Number 2) Date 3) Currency 4) Just Text. So why are letters allowed to be typed into the Number column, or the date column If I'm using the wrong property, then what would be the correct one I don't want to use validation - b/c then it's too late. I want to prevent a non-legal character from ever being written into the cell. Thanks. See this thread . The design goal of the DataGridView was to create a flexible grid control with all the most common features, while recognizing that almost everyone will have special needs that can't be satisfied by the common features. The control had to cover ...Show All

• Jonas Pranckevicius Form Hide triggers Form Closing, why ???

  Hi I am working on a legacy code [but managed, C++/CLI] project and I have add a popup dialog during the initialization process to show the initialization progress. The initializtion is one giant piece of code and must not be changed. Initialization series of events are fired for each component and the status popup dialog must listen to those events and disappear after the initialization is complete. Same thing for uninitialization. So i have created a thread just before the init starts and created the popup dialog [StatusForm]. That form listens to the events fired during the init process.

When I add the OLEDBConnection and OLEDBDataAdapter objects to the second form, everything works.
