Create A Simple Macro In Order To Run A For Loop?
Aug 19, 2009I am using Excel 2003 and I am wanting to create a simple macro in order to run a for loop and then have the information output the numbers to cells.
Sub ForTest(i As Integer, j As Integer)
For x = i To j
y = Rnd

This is my code. Now how can I print my x values to the A column and print my y values to the b column so that they line up as a pair of coordinate points.
Order Of Creation Or Adding To The Parent Control Determines Whether Or Not A Control's Dock Property Supersedes Another's
Jun 17, 2010i frequently have troubles with the dock property. it seems that either the order of creation or adding to the parent control determines whether or not a control's dock property supersedes another's. e.g. a control with the dockstyle fill will overlap with another docked control on the same parent. does anyone know what the rules are to determine how docking will behave; particularly in dynamically created GUIs?

I have a few panels that contain the controls, how can I check them all at once rather than use that code above and just change the panel number each time? It'll get pretty messy if I have to keep pasting all that code and just changing one number.

Aug 9, 2010I've created a custom control in VB.NET on .Net 3.5, in VS2008, which contains a load of custom properties, including RSS feed address, proxy address and proxy port.This control is an RSS ticker, which works really nicely, but doesn't initially run at all, and from stepping through my code, this is because none of my properties are being passed data from the containing form, until after the control has been initialised, and the code behind the control has run.

View 2 RepliesChanging A String To A Control?
Dec 1, 2010I am reasonable new to programing and have ventured in to using VB.net after creating macro's etc in excel, as this seemed to be the easiest transition into the world of programing.I am creating a application to work with an access database and before I submit the forms textboxs to the database, I check to make sure each field is filled in and if it isn't then I highlight the field by changing the label back colour to orangered.
What I have is a bunch of textboxes and a label above each saying what the field is. so for example the textbox name is txtBox1 and its label is lblBox1, txtBox2 - lblBox2 and so on.So what I thought I would try and do is, as the user leaves the txtBox after editing, the label background colour would be changed back to transparent.
As I have multiple txtbox's I thought I could do this using sender to get the name of the txtBox on leave, strip the first 3 letters txt and change them for lbl cast it as a label, then change the background color but I cant seem to convert my string to a label control. can someone help me with what am i missing or not doing.

Changing The Orientation Of A Win Control?
Dec 2, 2009I need to allow the user to rotate a control (the control inherits from a TextBox) in 90 degree increments so the text can be read from either side, or even upside down.
I'm guessing I could override the control's paint event and just paint it in the orientation that I want, but I'm just wondering if there's a quicker/built-in way?

View 2 RepliesForms :: Changing Look Of Tab Control
Sep 17, 2009I'm quite new at this but I'm trying to change the look of a tab control other than the options provided in the control's properties. In short I want to create a large tab that will fit a picture but I don't know how to change the size of the tab. I also want to make the control look somewhat different than what the control provided with VS.NET looks like.
What I need to know is how to create a custom control that operates the same as tabcontrol but looks different than the traditional control provided with VS. I tried looking up how to create a custom control but all I could find was how to create one programatically and I don't know how it would apply to a tab control. Maybe the only way to do it is programmatically but I would rather play with the control in the designer than having it appear only at runtime.
IDE :: VS 2008 - Controls - Changing The Look Of The Control?
Oct 26, 2010I'm trying to change the look of some controls in VB.An example would be a button, I now have a stack of 4 images on top of eachother. By using the mouseover events and such, I get the same result as a normal button. However, I'd like to be able to insert those images into a normal button like thing.
I know it's possible to do this by creating a custom control, but that'd end up with the exact same code, just in a different file.
However, the real issue would be a dropdown box and slidebar. I'd like to get them to look nice with my theme. (Background, buttons, borders. Things like that..). I got absolutely no clue on how I should do that.
I know that there's a tool to create controls, but that's from scratch and I can't get a grip on it, at all.

Webbrowser Control And Changing Size?
Aug 20, 2008I am creating a program with a web browser component, and a tab control. Default, the web browser is anchored to the toolbar. In my program there is an option to make a toolbar at the top of the form visible.false. Is there a way to make the web browser anchor to the top of the tab control when the toolbar is not visible, and anchor to the toolbar when the toolbar is visible?? I have experimented with docking (fill) but then parts of the web browser become covered by the toolbar and status bar. I am still relatively new to visual basic 2008 so if you could please explain or provide code.

View 2 RepliesRe Order Column Order In A Data Bound DataGridView?
Apr 17, 2010I have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.
Changing A Control's Properties In A Threaded VB Application?
May 11, 2011I am running into an issue with changing properties of controls on a VB.net project that I am working on. The portion of code that I am having trouble with is re-enabling a couple of buttons and a ComboBox after a Threaded operation completes. The point of it is to disable the buttons after clicking the main "run process" type of button (called cmdCrawlSearch) so that the process can run on a new thread while the form is updated with the status. I was able to learn about Thread Safe calls using delegates in order to update the Text property of the TextBox (txtOutput) on the form, and thought that enabling buttons would be just as easy, but when I am trying, I am either getting an "Object reference not set to an instance of an object" exception, or an "Exception has been thrown by the target of an invocation" exception (from the current version of code) with the InnerException being the Object reference exception. I am posting the portions of code related to the issue, then below it is the InnerException name and stack trace. Perhaps I am not using the Delegates correctly (since I still do not fully understand what can and can't be done using a Delegate.) Or there is a better way to do this.

Apr 6, 2009Well I'm not sure how to describe it so i uploaded an image that has 2 different control box positions.

The one on top is set up as Render Mode=System while the other image is set up as Render Mode= ManagerRenderMode
Both applications were developed in VB using VS2005.
Each one has its MDI container and their MainMenuStrip set up..
What property/reason would be causing this? I just created a test program simulating the same case (MDI container with child forms) and everytime i maximized the control boxes appear in the correct position.

Changing WebBrowser Control Contents Before First Render
Aug 10, 2006This problem is with the WebBrowser component. The code posted below is what I am trying to insert into the control before it renders the page for the first time. This question actually stems from this post: [URL]. I am developing the application in C#, however the problem is not really language specific.
When I have a page that has a javascript call to:
window.print()
I am wanting to override the print method so that pages do not pop up the print dialog. I can do so by inserting this into the top of the html:
window.print=function emptyMethod() {};
I now just need to figure out how to get this code into the document html before the browser control renders it for the first time. I have tried a number of things (for a complete list, see the post listed above), all with no success.
