I have set the panel to autoscroll and added scroll bars but they do not scroll far enough... They only scroll about 2cm.
In VB 2008, if one drops a vertical scroll bar on a form, by default the maximum value is 100, the minimum value is 0. If you place code in the scroll event to put the scrollbar value in a label, then run the program, the values in the label will range from a low of 0 (expected) to a high of 91 (unexpected).Why is the maximum value displayed in the label at 91 and not 100?
View 7 RepliesI've got a vertical scroll bar and I noticed that it's .Value is at a minimum when the bar is at the TOP (Why is that anyway?). Well, for visual feedback purposes I need it reversed where .Value is the max when the bar is at the top. Now I realize I can just manipulate the .Value in the software to get what I want but I was just wondering if there was a property I could set to just reverse it. I looked at the Object browser and couldn't find one. Sorry about these simple questions it's just that there are SO many properties and methods to learn...and I'm amazed anyone can remember all of these....
View 3 Repliesi have a textbox with hexadecimal values and i would like to use the slidebar/scrollbar to change the values (increase/decrease) then save the final values to a text file. To prevent the program from writing to many times to the file, i decided to use a timer. As long as the user still making changes or controlling the slide/scroll bar the timer will re-load (5 seconds). When the user is done modifying (no more dragging or clicking on the arrows) at that time the timer already expired, then the value get recorded to the text file.

View 5 RepliesI am creating some help files by using a TabContol box, on one of the tabs I need to have the scroll bars to be able to scroll down to see all the info.In nearly all software packages that I know of, you can also use your mouses' scroll wheel to move the scroll bars. This is not happening for me in this particular situation. I have looked for a setting in the TabControls properties settings, but cannot find anything to enable the mouse to move the scroll bars.
View 2 RepliesIs there a way to automatically show scroll bars on a multi line edit control only if they are actually required?
i.e. If the text is small enough to fit in the edit box, don't show scroll bars and if the text doesn't fit show the appropriate scroll bars (i.e. vertical, horizontal or both).
Of course I'd like this to be all automatic and not have to recalculate the size of the text myself every time the user adds or delete a character.

I have a picture box that is wider than the screen, with a stretched image. Can I put scroll bars on this picture box?

View 2 RepliesI am making a color box that changes color when the user presses on the scroll bars.I have 3 scroll bars for RGB I have bars' properties set to min:0 and max:255.The following code does not give me the gradual change in color when pressing on the scroll bars. I keep getting a solid red, solid blue, solid green when pressing scroll bars.
Private Sub HScrollBar1_Scroll PictureBox1.BackColor = Color.FromArgb(red:=255, blue:=0, green:=0)End Sub
For each bar I've changed the code color respectively. anyone show me how to get the colors to display on the picture box gradually instead of in one solid strike?
I would like to have the text alignment of a cell move to the Middle Left if there are enough records to require the Vertical Scroll Bar to be used, if not then the Text Alignment hould be Middle Center because of the size of the DGV that I want to display on my form.

I am building a basic web browser that I would like to not have any scroll bars (I can do this by setting the "ScrollBarsEnabled" button to False) but also still be able to have the scroll fulction via keyboard shortcuts.
IE when you press page up and down the page scrolls, but when they are disabled you can no longer use the page up and down keys to scroll.
Is there any "scroll function" in the browser like WebBrowser1.scrolldown etc that I could use? that I can have key strokes trigger?
A bit of an over view, the web browser is hosted in other software that has customizable buttons, these buttons can be set to send key strokes to the hosted app in this case my web browser.

View 3 RepliesWhat is the correct way to find the client area of the webbrowser control, WITHOUT the scroll bars ?
Any area/rectangle I get from the control seems to give me the entire control size, including scroll bars wether they are there or not.
I have tried detecting whether scroll bars are present and finding how wide they are to subtract from the entire control width, but have found no reliable way to acheive this.
I am trying to find the actual size of the window I can see if when the web browser control is showing the web page, not including the scroll bars.
I'm having a problem where I have elements such as Listboxes and Rich Text boxes that I want to set to size automatically in xaml according to the size of the window, but I only want it to resize to the size of the window and then put scrollbars if the content is any bigger than that.
Unfortunately, the only way I can get scroll bars to work is if I set a specific height of the listbox/rich text box (which does not work because I want it to automatically resize to the height of the grid that it is contained within, which is generally the height of the window (auto).
How can i put a scrolling a buttons?I want a put a multiply buttons vertically and when it the control exist beyond there size of the form will automatically show a scroll bars...Is there have a control that i have to use?
