how to remove a backgroundimage in the code whenever I activate colordialog :
[Code]...
I have a backgroundimage on the Me.(form1), I want it to be replace by the color choosen by the user with colordialog, right now it only changes every other form because the : me.backcolor = colordialog1.color has a backgroundimage.
I been trying to create a section for my program to change the backgroundimage property of the main form. let me show the code: (some parts may be bad written but I was trying to try to find the problem) this code is a click event from a button
[Code]...
A tabcontrol's backgroundimage caused severe flicker problems when resizing a windows form. By setting that property to NONE at designtime and that adding it at the very end of the processing pipeline & after the window had been maximized, the flicker problem on initial form load was solved.
HOWEVER, now when a tabpage resize event is fired, I would like to remove that image at the beginning of the resize and add it back to the tabpage at the end of the resize event. The following code however does NOT work. I get an error in the resize event, Property cannot be found.
Private Sub Form1_Shown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shown
TabPage.BackgroundImage = My.Resources.GraphicallyIntenseImageToDraw

I was making a program where it takes text from a textbox on one form, and places into a textbox on another form. If the first text I am taking says "test" Then the buttons code would be:
Form2.TextBox1.Text = Me.TextBox1.Text
This works, however, if there were two textboxes in the first form, and I wanted this:
Form2.TextBox1.Text = Me.TextBox1.Text
Form2.TextBox1.Text = Me.TextBox2.Text
- this would not work because one of them will override. I wanted to know how I could send a key into the form just once. I have tried this:
Form2.TextBox1.Text = Me.TextBox1.Text & ("{ENTER}")
Form2.TextBox1.Text = Me.TextBox2.Text
had a quick question that I dont think is too difficult, the solution just isn't too apparent to me.I put an option in my program that will allow a user to redownload a setup file and repair a program installation and I wanted the program to automatically launch the msi file and pass a command line arguent to use the repair function in the installer.This code works perfectly to launch the installer, but the user has to manually click repair.
View 6 RepliesI'll explain this briefly as I need to be sure pretty quickly... basically, I'm developing a game. after the user gets 5 points, an alert box comes up saying "proceed to next level"... on the next (second level) I want the background image to change....
Now the default background is not a picturebox, it's actually part of System.Drawing.Bitmap I am using the same form throughout the entire game, so when it says "Proceed to next level" the game stays on the same form... Here's my Select Case statement to tell it to change the background image:

View 3 RepliesIn my old VB6 programs I use control events like Keydown to activate code. The code is the same for all text controls. However, I am hoping that there is a efficient way of handing this in VB.net. Using VB2010.
Private Sub txtField1_KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles txtField1.KeyDown
ButtonState2()
End Sub
Private Sub txtField2_KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles txtField2.KeyDown

I have been developing a calculator for complex math. (Much more complicated than +,-,/,*, and above your usual scientific calculator)Its works quite well .In past programs I have used "private functions". I know that you give them a value and it returns on back. But what if you dont want to recive or send value? My example for this is a function I am attempting to make called "Autopi".The idea of Autopi is that whenever a mathimatical operation is about to be performed textbox(s) are cheked to see if they contain pi. (3.14 or 3.141) If they test positive Autopi will continue pi to however many places have been specifyed in the program. (Currently 300 places just beacuse i can :) Before the Autopi function does this it chekes to see if variable "pi" = 1. If it does it proceeds if it doesent its job is done
How would I create a code that can be called apon to activate but not recive or send any information through the program.And just to clarify what I mean by that is it will read information out of a textbox and write into it. But it wont actualy recive anything or send anything back from where it was called apon.
The error it has is that when one of the text boxes is changed the code changes all of them triggering every single function to activate. Is there a simpler solution other then recoding it from the start? also each different Private Sub is identical basically.
Public Class Form1
Private Sub K_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles K.TextChanged

I would like to know some stuff here:
1) When dll is injected how can u activate a function?
2) What is a class exactly in a dll?
3) Can you design a class?
I have a program where the main form is called (shown/activated) via a keystroke combination. When the form pops-up, I've set the focus to a textbox to begin typing right away.
When the keystroke event occurs, I have:Me.Activate()And in the Form_Activated event:
Textbox1.Focus() Simple right? It works the way I want it to, even after I've compiled and run the EXE, but ONLY if Visual Studio 2008 is running. Once I close my project in VS, with the program still running outside VS, the form is shown, but input focus is not set to the textbox.
Input focus is however still set to whatever it was previously, like a word document for example. My form will be topmost, but if I attempt to input text, it would still be entered into the word doc. why having my projects' source open in VS has anything to do with running the compiled EXE of said program?
I've even tried API calls to SetForegroundWindow and ShowWindow with the same result.
I would like to ask how I can select an Excel worksheet via code in vb. I looked but I only came across something like the below:
Private Sub Button2_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button2.Click
Dim objSheets As Excel.Sheets
[code]....
with the line: objSheet = objSheets(1), but because the tabs can be in any order, using the index isn't really helpful to me. Is there a way to select a worksheet by name in VB 2008?
Perhaps something like the : objSheets("MyWorksheet").select
that is something akin to the Excel vba code?
Load , Initialize , Activate . What's the difference among them ? Up to now I was used to the classic VB6 events , but it seems that in .NET they are different . I was used to these ones :Load / Initialize : both the first step before showing a form . One appeared in VB6 , the other in VBA .Activate : triggered when a form is selected .However I thing that now , not only they differ , but they also come in a different order ...
View 34 Repliesi am not able to figure out any code on how to do this. I am trying to make it so when the person chooses a color in the ColorDialog, the all my buttons forecolors go to that, then the dialog will show to pick a back color.
View 2 RepliesA user places the cursor in a table cell and clicks on "Table > Background Color" to edit the current background colour.Currently I have been able to detect the current colour (for instance a light blue) and set that colour in the ColorDialog (Colour swatches are correct and RGB values are correct).What I would like to do is enable the user to click on the "Add to Custom Colors" to save the colour. Problem is, it sets the first square in the custom colours area (which happens to already be filled in with another custom colour), rather than finding the next square that is white and set it there instead.

I can get the custom colours used in the ColorDialog (vb.net) by using yColorDialog.CustomColors, which will return me an array of colours as integer values
