Changing ColumnSpan And RowSpan Properties VS2010
Sep 17, 2010
I have a TableLayoutPanel with a Chart in the 2nd column and 3rd row, and it's ColumnSpan and RowSpan properties are set to 1 (the effect is that it takes up about a quarter of the screen). When I click the chart I want it to take up most of the screen. I was thinking that I would have to change it's Column/Row and ColumnSpan/RowSpan properties, but it might be easier to change the Column/Row values of the table itself. My main problem is that I'm just starting off on Visual Studio 2010 coming from VB6 and I have no idea where to access any of these properties.

I am working on an ASP.NET project where I use VB.NET within Visual Studio 2010. Some of the other developers on the project are using Visual Studio 2008. We all check our code into single SVN repository. I would like to start using Auto-Implemented Properties within VB.NET ...
Property FirstName as String
instead of ...
Private FirstName as String
[code].....
My concern is that this could mess up things for those using VS2008. What would happen if someone using VS2008 needed to modify my class that made use of Auto-Implemented Properties? I am assuming that since everything compiles down to IL code then there would be no issue in binary compatibility. Though a problem would arise when editing source.

I have somehow managed to disable auto-implemented properties in my VS2010 IDE how to turn it back on. Almost every article on the internet loves to explain auto-implemented properties but doesnt give you the crucial option of how to turn it on or off.

Okay, so I wrote a few custom ItemTemplates for VS2010 that implement IWizard in VB.NET (4.0). Straight forward enough. They work during my testing, but when someone else deploys and attempts to use any of them, Visual Studio throws an incredibly generic Exception has been thrown by a target of invocation error.
Stranger still, after they open up the project properties and try again... they work. Without changing anything. Anyone have any clue what is going on? Or perhaps even just a way of getting VS to give me a more specific error? I already tried devenv.exe /log but nothing out of the ordinary was there.

When using a TableLayoutPanel it is possible to put 2 or more objects in 1 cell by using a container in that cell. With a TableLayoutPanel it is possible to span a object over more then 1 cell (ColumnSpan).
Now I want to put 2 or more objects in 1 cell and using Columnspan at the same time. Example: Cel 0,0 exist of 3 labels and 1 label is in cell 0,1 too (see attachment).

I have a jQuery function that removes a row when the CheckBox is clicked. However, I need to also adjust the rowspan property because there are now fewer rows in the table. How can I do this in jQuery?

I 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.

I've got a groupbox on my form. I changed its font and fore color. The problem is that when I add a button or any other controls like a label, checkbox etc to the groupbox, the controls are automatically changing their fore color and font to that of the groupbox. How to prevent this?

I have made a program wherein you the labels are dynamically created with a press of a button. if you press on the label, the label would then change color from white to blue. my problem is that how will you make the backcolor of the label change when the button3 is pressed.
here are the codes. placed the whole thing since I dunno if you guys would understand what I mean.

PS here is the link to what my program looks like. link to my program . the button3 in the image is Reserve Seat.

I've been trying make a mdi notepad that can start up new instances of a "note" which is unique from the other notes as in you can save/change/cut/ copy/ paste in the individual notes without changing the properties of the other notes..something like a tabbed notepad but instead of tab control i have a mdi container. but i can't make it work. [code] problem with it is that whatever you cut/copy/paste in one mdi container richtextbox, it automatically cuts/copies/pastes in the other richtextbox controls in the other containers..

I'm writing a scheduling program that queries a MySQL database for today's appointments and uses a Table Layout Panel with employees on the top and times on the left to display the schedule. I am trying to add another table ontop of that table for each appointment and set the rowspan of that dynamic table to occupy the time slot of that appointment from start to finish.ll the appointments appear in the dynamic table and each dynamic table appears in the appropriate starting positions in the main table. When you are designing GUI's and put a Table within a table, you get a RowSpan and ColumnSpan option for that inner table. The problem I'm having is the dynamic tables are not giving me a RowSpan option, which I believe is because it was created using code and doesn't know that it's inside another table.Here is part of the code... This code is inside loops for each appointment of each employee
sqlCustomer = MyReader.GetValue(0).ToString()
sqlCompany = MyReader.GetValue(1).ToString()
sqlProblem = MyReader.GetValue(2).ToString()

I'm searching for a way to change the font size of selected text in a RichTextBox (rtf) having different font families (e.g. Arial and MS SansSerif) and font styles (underline, bold...) using the FontDialog, but without changing the families and styles. The following code resets all the font attributes, which is not what I want:

I'm making a control and I am trying to finalize my design time properties grid. I have several List(of Class) items as public properties and when I click on the design time menu (while testing the control) there is the word "Collection" and a button with an ellipsis (...) that brings up a neat pop up with the buttons Add/remove and all of the public properties of the collection's class on the right hand side. Basically for a non-collection instance of a class (with public properties) I'd like a similar button to show up. I know I could put all of the properties in the main control class and group them, but I like the pop up box feature. Anyway to duplicate this? (think font grid item etc.)

In the form design I set up a TableLayoutPanel, 20x20 cells and in cell (1,1) a PictureBox (called Target) containing the image of a small target. The properties box for Target shows some very promising properties, Column and Row - and if you overwrite the values in the properties box, the PictureBox obligingly shifts to the corresponding cell position in th design. However in VB it is not possible to refer to Me.Target.Row or .Column - neither appears during coding in the menu of properties, and deliberately coding either of them produces an error like
Error 1 'row' is not a member of 'System.Windows.Forms.PictureBox'.
1. Why does the properties box show properties that cannot be altered programmatically?
2. How can my program move Target around in the TableLayoutPanel?

I'm working on a Hazardous Materials label printing program. One of the options is to do an "NFPA" label. Since there are 4 values required with 4 or 6 options, the ratings are entered via radio buttons in a group box. That's working okay. I display values in the NFPA diamond as they're entered: left quadrant blue, top quadrant red, left yellow, bottom red. I'm having trouble with the label in which the rating will be displayed on top of a jpg diamond for the white. In this quadrant the text can be up to 4 characters. I can accept the text going into an adjacent block a little, but the corners of the label overlap into another quadrant/color. I reduced the font size which solved the overlap problem but the font is then too small and looks terrible. I tried to make the background of the label transparent to let the color come through correctly but that's not a valid value for label.background. I'm figuring that the transparent background is the best solution. What can I use that will accept a transparent background so the color shows through?
I'm trying to set the transparent property via label properties properties, not via code. Here's the code if it makes any difference:
Public Class NFPA
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Close()
End Sub

What I've done is create a User Control Library (Project) and I've added a single User Control to that project. The control contains a single FlowLayoutPanel, and I created a Property on the control itself to pass the FlowDirection from the Control to its FlowLayoutPanel child.
Build, reference, component appears in the Toolbox and everything works fine, but the property on the control does not appear in the Properties window when I go to edit it at design time.
