i have created a control as above, this control allows me to import a png with alpha channel and random shape. and then it can display on top of any other control, i.e. textbox, picturebox,etc. and the background should always show what right under it, instead of just show its parent control. it worked if it's static mode, ie stand still in the form. but when i tried to drag/move it, the control wouldn't render itself properly,and also goes underneath other controls.
Is there a way to enable a default pan behavior in the .Net scrollable control when you press down on the center scroll button, or Is that a behavior you have to implement yourself? You know like in some programs where you press down on the center button and it give you an arrow cursor that pans whichever direction you move the mouse?
View 1 RepliesI am just getting back into VB.NET, and I need to ask a question. I am doing a project for a class which requires iterating through 360 items in a scrollable control that will pause every so often. I am thinking I might use either a ListView or GridView, but I am not sure if this is the right way to go or if I need to use a different control all together.
View 3 RepliesI'm having a tough time implementing my own custom control that makes use of scrollbars if needed. The whole control itself would not be scrollable and only some portions of the custom paining would be scrolled, so the AutoScrolling capabilities of ScrollableControl would not work for me. But, I'm having an extremely difficult time in implementing a professional looking solution, where as the control gets resized, the scrollbars resize proportionality to be able to show a specified area.

View 6 RepliesIs it possible to make a multi-line text box still scrollable while it's disabled? The closest I can achieve this is to set the text box's ReadOnly property to false, which will gray out the text box, and still scrollable, but the text in the box remains black instead of being gray. Changing the forecolor of the text box does not have any effect. The color of the text changes back to black when I set ReadOnly to true. I want to be able to mimic the disabled text box visually.

How can I make a form scrollable?
View 2 RepliesI have a form in VB which is scrollable (using autoscroll) and when I currently click 'print', it only prints what I can see; it takes a screenshot of the viewable information.
Here's my code:
Private Sub btnPrint_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPrint.Click
Dim settings As New System.Drawing.Printing.PrinterSettings
sPrintForm.PrinterSettings = settings
settings.DefaultPageSettings.Landscape = True

I would like to build a form that has multiple picture boxes that a user can browse through and click on each one to select multiple items. The pictures will all be pulled from a single directory. After they have selected the items, they will click a button that will change the names on all the selected pictures. I know how to change the names, but I need some assistance with the picture box and loading the file names into a list or array. Not sure what it would be called. I am not even sure really if I would use a picture box or some other form item.

View 15 RepliesI'm building a break-timer application. The objective of this, in VB, is to have an application that lets me create a timer dynamically (maybe through a button click) that counts up (or down if you wanna call it that) to a preset point, then makes beeping noises like an alarm. This is due to my desire to no longer be late to and from my breaks at work.
I was able to create a super simple one that just had three timers that I could tick off, but I find myself using them for way more than just three uses. For example, I start one when I get in to count to the point when I need to punch in my timecard (our system is annoying about being exactly on time) then I start one for when my first break starts, then one for my break, then one for after my break but before my lunch, etc.
So, I wanted to have a program that does the following:Has a scrollbar-capable box that can scroll up and down.Each line of the Scrollbar-capable box has one of my custom controls in it (a wide, thin bar containing a field for how long to go, a start button, a display of time elapsed in seconds, and a stop button).
I can just click a button to create each control one line at a time.Now, I know HOW I can create these, but I want to know:Is there an existing type of box that would let me do something like this? Has someone already written this? Or am I going to be creating a COMPLETELY custom control that will be fairly painful to figure out? In which case, is this even doable, or should I just try something else?
im trying to make the form Dockable in the desktop on the righ side. I mean i can do this i can stick the form on the side but all other application are not seen in the full window coz my appz is still on the top and others appz under it.Size of the form is 200x1024, it is like administration stripe.So i would like to make other Winows in the system ended on the edge of my application. Is it even possible in VB?There is other way i guess to use some of the scroll(collapsible,expader) windows to the side of the desktop would do it as well but i dont know how to ?

I am an experienced programmer but mainly in 4GLs and assembly. Relatively new to VB programming, especially GUI applications. On a form I need to create an area that will be used to display *extremely* large TIFF images. typical image size would be 2000 pixels by 100,000 pixels. Typically I will NOT want to display the entire image at once, so the area will need to have scroll bars and/or other methods to scroll/pan around the image.
I have read about and tinkered with the bitmap and picturebox objects, including some threads about several different ways to implement scrollbars. However, I see that the picturebox size is limited to 32K pixels in both dimensions. I suppose that I might be able to copy various portions of the bitmap to the picturebox depending on scroll position, but that seems potentially quite slow and cumbersome. Can an expert developer who is experienced with these types of issues regarding the following:
1. Can bitmap objects be used effectively with TIFF images of the size I am working with?
2. an approach that should produce reasonable scrolling performance for these extremely large images without excessive coding effort?
3. For an image that exceeds the picturebox size when displayed at 1:1 scale, is the picturebox capable of displaying a reduced size version of such an image without lots of code, and if so, how?
4. Many (most?) graphics display objects count on all of their display data being stored in memory rather than on disk. Would that be true of a TIFF image loaded into a bitmap object and displayed via a picturebox? If so, the amount of RAM required in order to buffer the entire image in memory could be a potential problem for images of this size. Is there an advisable way to have the picturebox or other display object only load portions of the image into memory on an as needed basis, and purge them once they are no longer required? Are there any built in objects/methods/properties or is there any sample code to show how to do this?

Is there a way to bind the text property of a control to an expression? I have a user control that I add to a FlowLayoutPanel. You can see I have 4 controls in the FlowLayoutPanel below. The first control is a LinkLabel and the other three are my user controls which are numbered 1, 2, & 3. I'd like to bind the label that shows the 1, 2, or 3 to the user controls index within the FlowLayoutPanel.
If I happen to remove the 2nd user control I want the 3rd user control to now display 2. I could use the FlowLayoutPanel ControlAdded or ControlRemoved events, but wanted to see if I could do some binding first.

View 5 RepliesI have a WebBrowser control that have a webpage loaded in it. On the webpage I have a textarea control, like this:
<textarea name="text" id="textarea_obj">
My code is basically a file parser/editor and it handles most files fine as they hold a handful of records concerning family members. However there are a few files that crash when trying to deal with them. Here is the problem.Each family member record creates 3 tabs that hold an average of 3 group boxes each. Each group box holds an average of 3 text boxes.So each member record creates 3x3x3 = 27 text boxes and some files get up to 289 family members which = 7803 text boxes.
The problem is the rare file with 400+ member records = 10,800 text boxes which causes a crash due to using up all the window handles. Each member has a separate tab page (with 3 subpages) but really only a dozen or so member pages are visible in the GUI with scroll arrows to move through them so I was thinking of somehow making the GUI a scrollable window so the tabs get built, displayed and disposed as the user scrolls left and right through the member tabs.
The files are parsed into a 3d list DataList(x,y,z) where x is the page number, y is the group box number and z is the text box number. So all the data is available. The code then traverses MyList and builds GuiList(x,y) where x is the page number and y is the groupbox number with all the textbox.text linked to MyList(x,y,z) locations so all text changes are reflected in the MyList.
I already have a memberCount variable and I am thinking of building, say, the first 30 member tabs with the middle 10 being visible in the GUI. If the selected tab > 20, then dispose of the first 10 tabs and create tabs 30-40.I am thinking I will keep all the member tab pages so I don't have to deal with inserts and indexing problems but just dispose all the group boxes and text boxes for tab pages out of view. I already have a deep clone sub that clones members when the user wants to add a new family member and I am thinking I will have to add something similar when a tabpage is passed in for disposal, it traverses and disposes each text box, then disposes the group box for each group box on the tab page.Additionally, another routine will rebuild the group boxes from the data held in MyList(x,y,z) when a tabpage(x) is passed in.
