Visual C# Thread Form issue
I have a form "MDIMainForm" where i am starting a new Thread so check some data in a database. This Thread loops infinetily and opens up a new form "popUpMsg" if relevant data is found. The problem is that the "popUpMsg" form is not visible when it is created in the Thread. However everything works fine if i create the new "popUpMsg" form in the same thread from the "MDIMainForm". However i can not do this because my application pauses until the "popUpMsg" form is closed I am not sure why i can not see it. but i know it is there. (i print a line in the Console to know this) Any ideas I would appreciate any help you may also wish t ...Show All
Visual Studio Express Editions Error "The string binding is invalid" on application exit
Hello again, I am getting an error when my application exits. It happens after the last object of the main function is destroyed. I guess it happens during the destruction of the static objects, but I can’t find which one because the debugger says there is no source code available for the location of the error. These are the messages sent to the output window at the application exit: The thread 'Win32 Thread' (0xb00) has exited with code 0 (0x0). The thread 'DebuggerRCThread::ThreadProcStatic' (0xf7c) has exited with code 0 (0x0). First-chance exception at 0x7c812a5b (kernel32.dll) in padol.exe: 0xC0020001: The string binding is invalid.

Visual Basic More flat file questions
I've lots of success using the following code snippet to load my user screens, but I am having a problem because of the size of the input file. The Supplier file contains 845 rows with 11 fields of data per row. I think I want to load the entire file into memory and then be able to access the data on the fly, rewriting the file back to disk upon close of the application (since there is the possibility of data update). Using MyReader As New _ Microsoft.VisualBasic.FileIO.TextFieldParser( "C:\Program Files\Papillon\Vendors.txt" ) MyReader.TextFieldType = FileIO.FieldType.Delimited MyReader.SetDelimiters( "," ) Were this 10 years ago, I would build a multi-dimensional array to store the data, ...Show All
Windows Forms DataGridView - user selecting columns. How do I do that?
Hi. In my DataGridView, I have set it up so that I can display more than the 655 columns which are the default maximum that DataGridViews can handle. You can see this previous post with an example adding 1,750 columns here (my source at the bottom of the page). What I want to be able to do now is on the column markers at the tops of the columns, I want to be able to click and select columns (either singular or multiples by clicking) in my DataGridView, like you can do when selecting entire rows. Once I have selected columns, I want to then use my Context menu to allow the user to select functions they wish to perform on the selected column/columns! I have tried things like: this.dataGridView1.columns[0].Selected = true; I ...Show All

Visual C# SImple Inheritance Question - Inherited Form
In VS 2005, C#, WinForms app I have a form "BaseForm" which contains a 'protected' button. The button's click event code is 'MessageBox.Show("BASE FORM")'. I have another form, "ChildForm" which inherits from "BaseForm". In the inherited button's click event code is "MeaasgeBox.Show("CHILD FORM") When I run the child form and click on the button, first "BASE FORM" pops up, then "CHILD FORM", so I guess the code in the button on the child form does not override the code in the button on the parent form. 1. Is there a way in the child forms button click event to prevent the code in the button on the base form (MessageBox.Show("BASE FORM")) from executing 2 ...Show All

Software Development for Windows Vista HandleExternalEvent activity in Parallel
I have a few activities in parallel that listen for the same event. With the event arguments I will see which one of the parallel activities to execute. It seems though that the event is only fired in the first activity and not in all the activities waiting for this event to fire. Yes, but in the problem statement, he indicated that he was going to choose which branch of the parallel to execute based on the event arguments; leading me to believe he does not want to run both branches.

Software Development for Windows Vista How to pass a GUID to a WebServiceInput activity ?
Hello. I have a trouble which is similar to the thread you sent. I am trying to build a sequensial wokflow which contains a webserviceInput activity not as a starting activity in the workflow of the workflow, I use persistence in web.config and the persistence works fine. The problem is this: supposing I start the workflow from a window form. I get to the webserviceInput activity and the workflow is being stored into persistence as it should do. Then, I want to continue the workflow instance by calling the webserviceInput activity, but I do not know how to send the GUID to the webserviceInput so it will know which instance to open. I saw that when calling via HandleExternalEvent activity, I can send the GUID but when I am ca ...Show All
