View 1 RepliesI got a combobox, that when the texted is changed, its supposed to run a query to update a field in my database. Here is the issue The event im using is TextChanged, well unfortunately when the page loads, it changes the text when populating the values. Is there a way to make this event wait to fire until after the list is populated? Ive ran into this problem before with datetimepickers, but I was able to offset it with a boolean, but this combobox is calling the textchanged event everytime it adds an item to the list.
View 1 RepliesI am trying to write a program using Visual Basic 2008 Express Edition that will automaticlay generate multiple Command Buttons that have different Texts and perform different commands.For example I want to generate Button_1 and Button_2 where Button_1 when clicked enters the value "1" into a textbox and Button_2 enters the value "2" into the same textbox.I know this can be simple done by using the designer and wirting the code in the Button_1_Click, but what I want to eventually achieve is for various buttons to be generated across different Tabs in a TabControl.So far I can create a button on a windows form using code, but the button has no purpose so command is assigned to it. The code i've used is listed below:

I have a simple vb.net app written using MS Visual Studio 2008 with SP1 and .NET framework version 3.5. This app simply queries a MySQL table into a dataset, makes a csv file from that data and then uses Oracle SQL*LDR to load a local Oracle table. Nice and simple.
This app runs fine on just about any computer or workstation I have tested it on with no issues but when I move it to the workstation it will live on...it shuts down just before it hits the load event. I have tried to capture any errors but so far there do not seem to be any errors generated at any point...it simply terminates with no explanation.
I even went so far as to recreate the project from scratch and still got the same result. this phenomenon only seems to occur on the very pc I am expected to deploy to.
the only thing I know for sure is that it is getting at least as far as the declaration section of the form. Once it has dimmed all objects/variables/etc..it seems to just shut down.
I have two forms. On form one, I have a serious of check boxes and in form two I have functions relating to those checkboxes. When the second form loads, I check the Checked State of the Check Boxes, and run the appropriate functions. This is working just fine. The problem I have, is that the second form doesn't show until the functions that have been selected have completed. It would be ideal if the form would load and then run the functions.
I don't think that I could have everything run on startup, but hopefully there is another method. I know I could load the second form and then just run the code in the previous form, but this is less than ideal, because I can't show the second form as .ShowDialog and I want to be able to split up the code into the other form so that it's not so crowded and easier to read on the first one.
I've been following a codeproject article on using the interop forms toolkit (basically a way for developers to slowly upgrade their VB6 projects to .net by allowing .net components run in VB6)

While the .NET form is working fine in all other testing projects and environments, I've found that the Form_load event is actually firing twice once it's in executing in the VB6 runtime.Not only annoying, its forcing my initialization code to execute twice (causing all kind of problems on the second run).
If (runBefore = True) Then
I've been working on creating forms and objects through code in the the load event of Form1, truthfully theres a few questions I have under this one category but to start I want to create a button click event that will check what button was pressed then set that button to a variable. I want the event to treat the button that was clicked like it was that buttons click event.Here's a shortened version of my code (Lol if you can call this short):

I am trying to develope a small graphics application in VB.NET. My startup form has a picture box with a background image loaded from a file. The user can click spots on the picture box and this draws some circles on it. On exit the coordinates for these spots are saved to a file.In my form load procedure I load the background image, the coordinates for the graphics(saved from the last time the program was run), and then call the drawing procedure.
The drawings appear for an instant and then dissappear. If you click the picture box the graphics re-appear.The form works fine once you do this.I guess the picture box is refreshed by the form load event and this is causing the drawings to be wiped.(I stalled the call to the drawing procedure by using a timer and this works but I am sure there is a proper way of fixing this)Is there a way of ensuring a form is fully loaded or making sure the drawing procedure occurs only when the form is fully loaded?

I have a form for which the form load event only fires one time. When the program starts. It will not fire again until I end the program and restart. I have tried .show and .showdialog, but it acts the same. I have read about form load events loosing the handles, but my code looks exactly like it should.
Here is the load event code
PrivateSub frmBilling_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) HandlesMyBase.Load
LoadClients()
LoadTherapists()
LoadCPT() EndSub
Here is the code that calles the form.
PrivateSub BillingToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BillingToolStripMenuItem.ClickfrmBilling.Show()
frmbilling.show()
EndSub
I've been having a problem setting certain items in a listbox as checked when the form is loaded. I have tried putting the code in the form_activate, form_load, and form_shown events and each still crashes when it encounters:

How can I make an event for a tabcontrol which has Tabpage1, Tabpage2, Tabpage3, and so on.. For example... There's a label outside the tabcontrol (Label1). If tabpage1 is selected, how can I make the label1's text changed?
View 1 Repliesi dont really think its that hard to make, but i dont find out how.

View 2 RepliesI got how to get a webste source and set the value to label1.text but the problem is that the code searches for the word and removes everything before that word and everything after ">" (ex id=word word = "2332"> I can remove everything before the first word and everything after >) but my problem is that I cant remove the " because I have to close it like " " and then my label1.text is 1" or 13". So is there a way to remove the " from the label?
View 2 RepliesIf I pass Label1.Text through a function it treats it as an object and not a string. Which is good.
But when I do something like:
Dim temp As Object = Label1.Text
And then pass it through a function it treats it as a string, which is to be expected. How can I make it so I can set Label1.Text to an object the same way it would if I just passed it through a function.
Edit: Here is specifically what I want to do
Public Sub test()
setIt(Label1.Text, "Test") 'this works
Dim temp As Object = Label1.Text

I wanna have Label1 change to a specific location whenever NumericUpDown1.value = 10 or more.

I got a Sub which processes a code, and then it does whatever the code said. Example.
Code = "Black" -> Turns screen black.
Code = "OFF" -> Turns off the PC.
And so on.
If I call that Sub from Immediate console, It works perfectly. But if that Sub is called from an event, It does nothing, and usually throws an Exception. I read somewhere that I can fix this by using Threads, but I don't understand how that can help and make it work.
How can i make it so that label1.text = the number of time timer1 is ticked ?
View 2 RepliesI have a string which I have pulled out of a text file as shown below,[code]and I would like to split it up and get the numbers into individual string() arrays. I have tried using split , but the problem with this is that it only splits up characters with one space between them, and there could be multiple spaces between characters so it ends up storing blank spaces it a string array.[code]
