Interface And Graphics :: [VB2005] Enable Import Button In The GUI?
Nov 20, 2008
how to enable the "import" button when at least one of the checkboxes is checked.I have two buttons : "Deselect all" and "Select All" for the checking of the boxes, to import the specific files' data they want to Excel. (the files are in listbox, and the checked boxes is for selecting the files' parameters that they want to see in excel)
One option:When the user deselect all, the "import" button is suppose to be disable to prevent the user from importing the files' data parameters.
2nd option:(if i do not want to disable the import button) or show message that they have to select at least one box and at the same time, prevent the import button to work if there's no checked checkbox. So my deselect all button code :
Code:
CO2checkbox.Checked = False
NH3checkbox.Checked = False
DBcheckbox.Checked = False
[code]....
but the button still remain disabled if I click "unchecked all" button and then checked at least one box. how do I enable it?And how do i...show error message and prevent the files' data to be imported when the user click "import" when there's no checked checkbox if I choose the alternative option of using message to alert them without disabling the button and yet prevent importing of data?
PS: If I did not click "deselect all" button but click the "select all" button, the import button is enabled and working.

How can I disable/dis-enable a window in WPF, similarly to what is automatically done while a msgBox is visible. I would like to have the main window disabled while another window is on top, but I can't figure out how to do this.Also, I'd like to know how to not have the other window show up in the Windows Toolbar....

I am developing an application for an emergency services organisation using VB 2008 that will enable users to select a map zone of a city centre and plot icons onto it, then save/export the layered map with icons as an image.My problem at the moment is that I am struggling developing the point where the user imports in the icon (for example, a flame icon where a fire started) and drags it around the map within the picture box to the required area.I want them to be able to select their desired icon from a series of commandbuttons and for the icon to 'appear' on the picturebox and be enabled to be dragged around and dropped as required. The organisation already has such a thing working in Microsoft Word (!) and that uses the ActiveDocument.Shape.LoadImage function on a pushbutton to import the icon and then it is placed on the map as required, but this is really unreliable for them.I dont even know if you can layer images onto an existin picturebox within an application in this way and then export as a flat image.

I got a graphic that I got to rotate about a specific point. So, I got to define the centerX and centerY, the point about which to rotate. For that, I am importing the namespace: "system.windows.media.rotatetransform"The following problem then arises when the above namespace gets underlined with a green curly line and when I place the mouse over it, the following message is displayed:"Namespace or type specified in the Imports'System.Windows.media.rotatetransform' doesn't contain any public member or cannot be found. Make sure the namespae or type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases."

[URL] This is for vb6, and I know this is a .net forum, but hopefully some one may know the answer as I have tried countless other places. The buttons appear properly after they are clicked or issued a .refresh command.

I plan on using a scrollbar for, well, scrolling an image. The image is 200x500, however, the only visible area is 200x250.
So I set the max value to 250, and the min value to 0. The idea is that if I drag the scrollbar's button to the bottom, 250 pixels will have moved for the image, right?
But wait, the scrollbar's button is.... very small. And the scrollbar is actually pretty long. Is there a way to make the scrollbar's button longer?

I was wondering if there is a way to have a button/label that would change the selected item color of the combobox from the standard black into a certain color (say green), but not change all of the items' color into green. This is for a to-do list type of application where a user clicks the button to signify that the current item is finished..This is what I was thinking (not in VB code) When button1 is clicked, combobox1. selecteditem. color = green

This is VB 2008, under Vista. I can't seem to change the background color of a button without the gradient disappearing.Strangely enough, you can even set the background color to itself and the gradient disappears. How do you keep the gradient but change the color?
Here's an example:
Code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Button1.BackColor = Button1.BackColor ' This should do nothing!

I have a form with buttons, and the user can change the colors of the buttons with the color dialog box for fun:
Button_Play.BackColor = ColorDialog.Color
There is a reset button to put the colors to how they were without any special coloring, but I can't get them to go back to how they originally looked.They go to gray in the middle, instead of the nice shaded blue/gray style. I have tried a few different things:
Button_Play.BackColor = Button.DefaultBackColor
Button_Play.BackColor = SystemColors.Control
Button_Play.BackColor = Color.Empty
I am using VB '08 Express on Win XP with the Desktop, Display Properties, Appearance, Windows and Buttons: set to Media Center Style and Color Scheme: set to Energy Blue. how to (with this theme) get the button to look like default after changing the color?

I need to visually moves the cursor using keyboard keys.
1) I need to get the mouse to where the button is
2) Simulate the mouse movement to the button from whereever it is
3) and simulate a button click.
Only after I select a button I can start drawing on my form. I have a code here, when I hold the Ctrl key and press the arrow keys, the mouse will start drawing straight lines. But what happen when I need to use controls like buttons, comboboxes etc.?

I'm developing a GUI for a touchscreen, so when user wants to scroll he/she uses their fingers. Now the thing is that the scrollbar width (with the vertical scrollbar) IS adjustable but the button stays the same height and isn't sufficient for a finger. So the question is : Are the buttons in the scrollbar allso adjustable in size/dimensions.

When a button is focused by pressing Tab key, a rectangle appears on it. Even if the button's TabStop property is set to false, when the button is clicked with mouse the rectangle appears. Is it possible to
stop the rectangle from appearing?

I need to disable a button after its pressed so the user does not have the ability to click it again as this would replicate the process in some cases. After alot of searching I found some tips - alot of code I found I could not understand.This is what I have come up with:
[code]...
I also read somewhere that I should use: System.Threading.Thread.Sleep(1000) to delay the process or something - not entirely sure why I would do this though.Although, the problem with my above code is that when the code behind page performs validation checks, it exits sub before executing my INSERT SQL code - so when it does this it also disables the button.I am not entirely sure if the above method is fool proof or whether it is a **** piece of code that won't work 100% of the time.On another website I found a script to put on the actual HTML page with <script> tags:
[code]...
But although this works, it does not execute my VB code in the code behind page so I am a little confused where to go here.

I'm being forced to write VB code to be used from within ACCESS 2007.My desire is to use a leftover copy of Visual Studio 2005 to write a system that will use ACCESS 2007 as the db. The problem is that the company will no longer support Visual Studio and .Net development. That means that whatever code.I write must be accessible from within ACCESS 2007 for future maintenance.How do I import externally generated VB code (including forms) into ACCESS 2007, so that I can use ACCESS to maintain the code?I'll post this question to the ACCESS forum also, and hope that someone can save me from having to do all my development within ACCESS.

I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.

I'm working on a design project where I have to use a Graphical User Interface that contains a drag and drop form. It consists of having a window dropped on a wall. Both of them are images to scale. I would like to know what kind of code I would have to use to show the x and y coordinates of one of the points of my window when dragged so when I drop it, I'm dropping in it on the desired coordinate of the wall.
