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?
My project needs to print a large PictureBox which during runtime only part of it is shown (as it's too large, width=4000 pixels and height= 2000 pixels) and to see the rest of the picturebox, user needs to scroll through the vertical and horizontal bars. On top of the picturebox, there are many controls which are loaded and positioned by user on run-time. Those include lines, labels, another picturebox with image and user-defined controls. Now, i need to write a print function which will print that picturebox to not too many pages in A4 size or A3 size. Not too many means less than 5 for both paper size.
1) How can i print the whole picturebox with all its contents and go to next printing page until the whole PictureBox is printed? I tried using the following code but
(i)The image of picturebox inside that picture box and user-defined control are not printed whereas others are printed. Why is that so? How can i print the picturebox including both the "un-printed"?
(ii) Even i can print out the picturebox, only the part where the picturebox is shown is printed. How can i print the whole picturebox including those parts which needs scrolling to reach?
Private Sub CmdPrint_Click() Dim rv As Long 'Picture1 is the picturebox to be printed.
[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.
Ok..I think it's very simple but I'm still a begineerI'll try to make it clear I need to draw a rectangle when I click on the button..what is the required code?

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:
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.?
im making a program that needs to make a new button for each .exe file in a directory? Kinda similar to PortableApps program that will recognize each program in the directory.
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 :
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.
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.
How can I set a button, so that when it is pressed, it stays in the pressed down graphic state. Then when pressed again it returns to the normal not-pressed visual.Make a button stay like this until pressed again: url....
Im working on a project that needs to print a report of one client.Everything went smooth untill i came across my multiline input text data.When i display it in the PrintPagePreview the text go's outside my page. Even when im printing it only the halve of my text is displayed. I googled and looked everywhere but i can't get a clear fix for it.
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.
drawing text on a window which is not the current form's window.I remember doing this in Win32 api with getwindowdc(handle) to obtain a DC for the Window, then textout() on the DC.
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.
Ok, I want to create a class that will handle a special rectangle graphic.In my form, I want to have two of these special rectangles. So, basically, I need two instances of that class in my form, right?I manage to initialize two, alright. But, how exactly am I supposed tomanage drawing/graphics etc in a class, and the results to be displayed in my form?
I was wondering if I could elicit some tips on how to procede with an interface design approach.That is. What is a good way to go about establishing a "work area" where one can have multiple "floating forms" in this area.Can you have a form which occupies the entire windows desk top and the other forms "float" in this space? the "floating" forms would need to interact with each other where pressing buttons etc on them would affect other forms on the "workspace") Or what would be a good way to start accomplishing that? Or is there a better way to get the same effect?
I'm trying to make a .dll that contains a lot of basic functionality that a program can use. Currently i am trying to use interfaces to make a lot of this functionallity independend of the program using it but i hit a snag. The Basic idea is that a programmer will create his own object using the interface discribed in my .DLL file. Then implements those functions as he likes. He can then instanciate a controller (found in the same DLL) and sends his custom object implementing the interface to that Controller. The controller can then be started and will take over all the work. I do not know what type of object is send to the controller and idealy i want to program it in such a fashion that i shouldn't care as long as the object send implements that interface.In code I am trying to achieve the following: (quite simplyfied)
.Dll: Code: Public Interface MyInterface '<----Decleration of the interfaceFunction GetData() As Integer Function SetData(Data As Integer) end interface
[code]....
this propperly. I know that the second i set the interface adaptor in the Controller VS comes nagging that it can not be converted to a "MyInterface" Class. Obviously i am doing something wrong. I can change the datatype that the controller expects to the "MyController" type but that would completely ruin the whole idea of flexibillity. I am hoping someone sees what i am trying to do and can point out where i made the thinking error.
Is this where i would post a picture of my interface and get feedback on changes for easier use? If not is there someplace on this forum or any other forum to do this?
So I decided to make my famous tile selector project, but instead of drawing in a form's graphics, do it inside a tabpage.Well, I managed to get it working, but it seems to... flicker.Normally, setting the form's DoubleBuffered property to True would help a lot there, but apparently, the tabpage has no such property.
When I invalidate the tabpage, I draw two images and fill one rectangle.Following past advice, those two images were created before, just once, and are stored in a variable so I don't create them every time I invalidate the tabpage.
