My HScrollbar will only go to 9 less than the specified Maximum value. I want it to go from 0 to255. When I set the Maximum value to 255 and run the program the slider indicates 246 when full right. I can get it to go to 255 by setting the Maximum value to 264 but this seems very wrong.
View 2 Repliesthe title pretty much sums up the problem: the existing HScrollBar control does not expose a MouseUp event. How do I go about adding this event to the control? I'm using VS2005.
View 8 RepliesI have successfully ported a VB6 application to VB.NET (VS2008, .NET 2.0). Much optimization and rewriting has been done, but there is one possible BUG i cannot overcome. I have a standard HSCROLLBAR control used for accepting a numeric input. The control needs to be disabled during complex computational routines to prevent additional user input. I am setting the enabled property to false and reenabling the control at the end of the calculation cycle. The control is enabled and disabled a few times, because some code has been placed in the onpaint event of a drawing area, and separating the calculation part from the drawing part will be a huge task.
Large changes are handled correctly. Small changes aren't. The problem is that the control freezes in a unknown state after clicking on the arrows. A second click makes the control (and its parent control box) jump up and over everything else in their container.The scrollbar remains functional only via the contextual menu. This happens both in debug and release builds. There are no overrides. Coding/Test platform XP SP3 (more than 1 machine).
There is no code whatsoever that handles neither the parent control nor the scrollbar repositioning and resizing. The only code takes the value of the scrollbar and passes to the calculation section. If I omit disabling and reenabling the control, everything works fine.i tried rebuilding the control from scratch. forcing enabling the control after it has gone haywire does not make changes, disabling the groupbox instead of the single control doesn't make any difference, debugging step by step confirms that things go wrong when drawing the controls within the private system form classes.
Do the VScrollBar and HScrollBar controls have a known Value bug?I'm using VB10. While testing some code I used a Horizontal Scroll Bar to change a value on the fly, I thought my code had some bad math in it until I discovered that when the bar is scrolled to the very far right the Value was not equal to its Maximum value setting like it is in VB6, the same happens for the Vertical scroll bar control, set the maximum to 100 the Value will only go up to 91, set max to 200 and value only goes to 191, etc.

View 6 RepliesI have a TopBar, A LeftBar, A VScrollBar, A HScrollBar and a Panel inside a SplitContainer Panel.The issue I'm having is that when my SplitContainer Panel is small enough to enable one of the ScrollBars, I will slide the ScrollBar and then when I resize the Split Panel, my Panel1 is staying where I scrolled it too.I'm having troubles thinking of the correct code to fix this.

I am trying to use the Web Browser control in my vb .net user control. I am using VS 2008. Finally, I will be calling my assembly (.dll) from a web page. I wanted to display the usercontrol with the web browser control inside this web page. The problem is I cannot proceed since the Web browser control cannot be called from a partially trusted assembly. Using VS 2008 I have created a strong name for my class, also added the <Assembly: AllowPartiallyTrustedCallers()> to the AssemblyInfo. But still the web browser control cannot be seen in my web page. Do you how I can make my assembly fully trusted so that it can access web browser control? If you have used web browser control, can you confirm if this step is really required?!
View 2 RepliesI am wondering if anyone has any idea how to make the controls stack and fill up the available space left by a control if the control is hidden or removed from the UltraGridBagLayoutPanel.
Example:
[Textbox 1]
[Textbox 2]
[Textbox 3]
[Textbox 4]
[Textbox 5]
If I hide [Textbox 3] as of now, it will disperse the space left equally and pad the remaining text boxes with the space. However, I would like it to do this...
[Textbox 1]
[Textbox 2]
[Textbox 4]
[Textbox 5]
Where all the text boxes will move up and [Textbox 4] will completely consume the space left by [Textbox 3].
I'm trying to make a label control transparent over a Panel control.However by setting the background colour of the label to Transparent, it actually sees right through to the form itself, not the panel as intended.
As an example we use a panel with a background as white, we make the label transparent, however it gets the form�s colour as blue.However, we are using a custom panel control and need the label to be transparent over the panel and not see the forms background.
1) How can I make the text in RTB control to change without clicking on it (RTB control) again? I notice that the event handler is mousedown so its only occurs whenever the users clicks on the controls. But I really have no idea how to do that. Anyone can guide me how to do that???
2) How to make the RTB's Back Color to transparent??? Cause it is not supported. Or is it I use the wrong control???

Currently, I've just got all four stacked on top of each other in the designer, and I'm toggling their visible properties to show each. This is becoming extremely difficult though, as now I have different buttons in each panel, and the panels keep getting accidentally put inside each other when I move them.

way to "reset" a tooltip, so you don't have to leave and re-enter a control to make it pop? I have a form that is pretty much entirely taken up by one control. I want to have its ToolTip text change based on which region of the control is being hovered over (which I can do now). I just have to leave the control and re-enter it to make it pop. I'd like to have the Tooltip pop, then if I move the mouse to a different location (still inside the control's bounds) have it pop-able again in the new spot.

View 6 RepliesIs there a way to not put the project name in the Inherits attribute?
I am working with vb and I have multiple projects, that have multiple web pages. In each of these projects I create controls that are reused in the web pages.
Each control I have is declared like this:
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="MenuBarControl.ascx.vb" Inherits="**projectName**.MenuBarControl" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
When I want to copy the control into another project I have to change the **projectName**. Having to change the project name for each project makes the code not reusable. Changes made to specific projects each time is not reusable.
I want to be able to omit the project name in the Inherits attribute. When I do that now I get an error

Parser Error Message: Could not load type 'MenuBarControl'.
