View 2 RepliesHow to programmatically change foreground color and make bold text in individual cell location on DataGridView control (Visual Basic)?
I use "dgMatrix.Rows(r).Cells(c).Value = x" to assign individual numeric values to individual cells in a DataGridView control. My question; is there a similar way to change foreground color and make bold the text in this cell, by specifying the individual row/column cell location?
For example; for cell (row 3, col 5) in the DataGridView make text in cell say red and bold or blue and bold so as to highlight and distinguish individual cell contents. As needed, I will also need to reset these properties (foreground back to automatic/black and font from bold back to regular); the reset could be done globally to the whole DataGridView as opposed to indiviaually by cell.
I just noticed this, but I had a for loop where I incremented beyond the number of elements in an array. Normally this would thrown an exception.
This was in a form load event, and all that happened was the rest of the code in the event never executed. If I wasn't looking for what was supposed to happen next I never would have known there was a problem!
There was no try catch block there... but I would think it would still stop program execution with an error.
Can anyone explain this? Do I have some stupid skip error checked somewhere (if this exists, I'm going to be really annoyed)? In a button click event I put the exact same code and it threw the error... it seems to just be a problem with a form load event.

I'm familiar with Throw New Exception(), and how this causes an application to "break" with an error at the Throw line itself.But what I'm after is a way to throw the exception within a function, and for the application to break at the line which called the function - not at the Throw statement itself.Is there a way of doing this, but without having to wrap the function call within a Try-Catch?
For example:
1. Main code calls function "DoThis()"
2. DoThis() runs and throws an exception
3. Code breaks at "Call DoThis()"
I have a project written in MVC2 and VB.NET. I use a lot of htmlhelper extension methods,and I have them all in a public module. They work just fine, and I can compile and run my project. I reference the namespace they are in with this:<%@ Import Namespace="MyProject.WebUI.Extensions" %>So, again, they work great, my project runs and compiles without a hitch.The problem is that each one of these extension methods is shown as an error:
Error 33 'TabbedMenu' is not a member of 'System.Web.Mvc.HtmlHelper(Of Object)'. C:ProjectsMyProjectMyProject.WebUIViewsSharedSite.Master 23 21 MyProject.WebUI

I have a VB .dll from a previous developer that I need to modify. So I de-compiled it with no errors and then exported the code. I tried to compile the project and get two syntax errors:

The error message just says syntax error, nothing else.

In addition, you must run Visual Studio in the context of an administrator account. I have never worked on anything like this before and for right now I would just like to look at the code. I Googled and found this: You can enable these features in the Add/Remove Programs control panel. In there you wiull find a link off on the left labeled something like 'Turn Windows features on or off'. Click that and you'll get a UI for managing the IIS features that are installed.
I looked there and don't have a clue what I should check. I'm on Windows 7. What should my approach be? I don't want to just clicking things in the IIS configuration console. The attachment is what I see.
I'm not sure what happened. I saved my project last night and everything was in working order. I opened it this morning and it's not recognizing a lot of the System methods and functions
