How can I implement a sub routine or function that does a test for number validation in text fields and then also returns the value of the text fields (if they were valid) back to the main routine?

I have a thread in an application which calls a sub routine Main(). The Main sub routine in turn call several sub routines/functions from with the same module,several different classes in the same application. Also some sub routines/functions call routines from a class library. Now say the routine/function in class library goes into a infinite loop and never returns. I would like my thread in the application to raise a event and display message to the users about the infinite loop. I am giving some sample code for the application.
Imports System.Threading
Module VMain

I am using a COM library in my VB.NET app that has an asynchronous execution method and signals my application via an event when it completes. The event handler is on a different thread from the calling thread. I want to invoke another execution on the main thread when I receive the completion event. If I call directly in the event handler for another execution it starts on the new thread. How do I marshal back to the main thread. This is done in a dll not in a form.
View 3 RepliesThis should be fairly basic but maybe the search terms are too general to find relevant answers.I have an MDI form with a conventional toolbar. When I open a small non child form I want to set focus back to this main form so the user can click the help button on the toolbar if necessary.
Tried frmMain.Select() and frmMain.ToolStripButton0.Select() at end of small form load but it doesn't work. The user has to click the help button twice, once to select it and once to open it. A minor problem but annoying.

I am using sockets to send message between computers. I send the messages alright. What I want is when the message "x0x" comes, the client must be closed within 5 minutes. Teh admin can cancel the request by sending message "-xx" as well. The routine that checks for incoming connections and accepts messages uses WHILE TRUE...END WHILE since it must always listen. Once I get a message, I need to fire a timer control or other that fires within 5 minutes. But the program cant leave the WHILE TRUE at all. If i exit it early, the timer fires and the program does get exit. How do I fire the timer or other routine while still the WHILE TRUE routine checks for incomin connections and messages?
View 5 RepliesI have a splash screen, the default from Visual studio. It loads up, is shown for a few seconds, then, when it disappears, the main form is loaded. Now here is the problem: the main form appears in the back, behind the windows explorer window I load the application from.
The weird thing is that this only happens on some computers, particularly Windows XP machines.I tried a lot of things like BringToFront() or TopMost = true in the on Load event of the form but nothing seems to change this.
is there any way to reference a particular code routine in VB.net external to the current loop/routine?Example:
If Var01 < 5
[Routine A]
Else
[Routine B]
End If
where Routine A and Routine B are code sequences at the end of the entire program -- such as outside of the current sub or class? The idea would be to reference an otherwise repetitive code.
experience on how to create an engine using C# (VB.NET is okay too) that is generic enough to handle most cases of MS Word text fields I need to fill with data I'm getting from a database?

View 2 RepliesI'm having a little difficulty Setting the .text value of a Textbox in an MDIChild from a Subby in a standalone class.
I'm at this point:

I know that the data exists because it displays in the Message Box ( MsgBox("first item = " & ds.Tables(0).Rows(0).Item("NameLast").ToString())) and the executes fine, but for some reason, I can't get the text boxes in LeadsMod2 (Open as MDIChild) to update.
I have a sub routine where I pull in information from a database. I want to use variables from this sub routine in another sub routine. I tried making everything public but it doesn't want to be friendly and share.
Dim strEmail as String
Public Sub readDB()
strEmail = "whatever@doohikcy.com"
[Code]....
The readDB would read the database and set the variables and do whatever it needs to do. Then when they submit the form it would e-mail the form to whatever the email address was.
I have basic text report (.txt) that is created by a custom application. My client would like it to page break at a certain spot.
Does anyone have a routine that would allow me to insert PCL code into the file so that when printed it page breaks? I'd search for certain text and then insert the codes just prior to the text.
Certainly if someone has a better "mousetrap" then let me know.

What i am trying to do is save text from a number of text boxes to a user named file then subsequently be able to reload the data back into the same text boxes at a later date.so far i have this which was provided for elsewhere on the web, this allows me to save comma delineated data to a file which is fine but i can't seem to reload the data. As an experiment i have just tried to reload it back into a rich text box to see if the process would work but nothing as yet.

The new command text returns data with schema different from the schema of the main query. Check your query's command text if this is not desired. I am getting this warning, whenever I add a query in a Strongly Typed DataSet which returns a single column.
Ex
SELECT DISTINCT Building
FROM Room
ORDER BY Building
When I give this query it will show me a warning. Because warning leads to a constraint error when ever i call the same function in a windows form.

When the button is pressed the line is written to the file just fine, but if I restart my application, which calls Refresh_OtherLog() onLoad, it displays the lines of the text file as one line with the traditional square character depicting a character return.

Is there any Windows API Routine to read something like that?Or could you point me an URL where something is implemented?I don't want a procedure to read the file line by line and comparing them with Line Input because blank spaces, empty lines and comments starting with " // " may appear too, and I don't want to take them into account, but also I need to save changes to the file, but only to the modified section, without having to read the whole file, and re-write it completely.
Binary access can't work, because I don't know what's the size of each "section", since the number of elements into it can change.
I need something like the "ReadINI" Windows API Procedure, but allowing me to read the "[XXX]" sections headers, and also the "<XXX>" file title header.
I get an empty string when calling the .Text property. Refer below for snippet:[code]The internet search advises to use Items(col).Cells(2).FindControl(..), the problem with that is FindControl finds the control by ID, BoundColumn doesn't allow you to insert an ID for it.

I tried searching for a solution, but couldn't find anything, so if I am re-asking a common question, don't beat me too badly. For a class, I have to create a form that allows someone to enter in the names of six students, as well as five test scores each. It also averages the scores, and displays them in a label.
What I am wondering is if there is a way to clear the text from all 36 text fields, as well as the 6 labels without having to do everything individually?
I could certainly go through, and write out txtField1.text = String.Empty 36 times, but it seems there would be a more elegant solution. Also, if there is a way to do so, would the same would apply for putting the data entered into an array, or saving it to a file?
I am writing a little program that does the following:Allows the user to enter a id number.Then when the find button is clicked, we connect to the database and run a select statement for the id.I am trying to figure out how to get the first name, last name and birthdate into textboxes on my form.
I would like to have a way to display a messagebox if the resultset = 0 so as to tell the user no records found.Then if the information is correct I am going to have a button to update the information which is going to call a stored procedure I have in place to update the record.how to make the connection which I think I have working and then loading the individual fields into the appropriate textboxes.
