One problem could be that you have not defined the workbook where the sheet Orders is. So if the topmost workbook is not containing such sheet, it will fail.
The need to optimize rises from a bad design.

You received numerous answers yesterday to this topic. Don't spam the board with the same question.
You can find the answer(s) here.

Because your dr object doesn't have a property or method called "cashierId".

Hello,
Im trying to follow this tutorial on this site:
http://www.codeproject.com/KB/vb/CustomAppAutoUpdate.aspx?fid=431225&fr=1#xx0xx[^]
I have added the code to my project and i get as far as the autoupdate.exe program opening up and then nothing happens for a few seconds and then i get this error:
Microsoft .NET Framework
Unhandled exception has occured in your application.
Object reference not set to an instance of an object.
Can anyone shed any light on why this may be?

I've never used his code, and don't plan on it any time soon.
You're going to have to ask him why the code bombed. Basically, that error means that you tried to execute a method or property on an object that didn't exist. Essentially, you did this:
Dim myTB As TextBox = Nothing
myTB.Text = "This will throw the Object reference not set to an instance of an object."

You can't do this using String.Format. How the fonts a rendered depend on the control that will show the text. Since you want both parts of that phrase rendered differently, you'd have to render them seperately.
You have a couple of choices. The first is creating a custom control that renders the text yourself. The second is creating a usercontrol that has a couple of label controls in it, each label showing one part of the text, and using different font properties to achieve what you want.

No Control I am using
Just Format the some parts od the String and show it in to the grid.

I'll say it again. You cannot do what you want using String.Format, or any other string manipulation techniques. This will ONLY happen when the text is rendered by some kind of control. For most controls, you cannot mix font styles, so this would prohibit you from using a single control to do this. The only control in the ToolBox that can render different fonts at the same time is the RichTextBox, but that control is a bit too heavy for your requirement.
|
|
|
|
|
You want to show F1 throughout your app, but where exactly are you planning to display this? What is the intended control that this should be displayed on? Depending on the control, you may or may not have this ability already.
If not, you'll be best off doing a custom control like Dave recommended.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

String.Format does NOT format the text like a word processor does, the font weight, underline etc is controlled by the screen control you put the string in. String.Format is really just an easy way of building a string.
For example
Dim str1 as string = string.format("My name is {0}","Bob")
Dim str2 as string = "My name is " & "Bob"
both give the same result.
I think you have misunderstood the use of the string.format function, hopefully this will aid your understanding.

Dim str1 as string = string.format("My name is {0}","Bob")
Dim str2 as string = "My name is " & "Bob"
According to your Example how can I make the "Bob" bold

You can't with string.format. All string.format does is replace the {#} part with the text after the comma. Try it a couple of times in the immediate window.
The color, size, bold, underline parts of the text are controlled by the font property of whatever control that you're trying to use. If the particular control is unable to display F1 without the underline, then you must extend an existing control or create one for your needs.
All we have gathered thus far is that its a grid of some kind. It may prove somewhat beneficial to try and post the code your attempting to work with so we have an idea of what you're trying to do.

Why do you have it stuck in your head that you can do this with String.Format or any other string manipulation technique?? IT'S NOT POSSIBLE! If you won't listen to the answers you're getting, why should we help you??

Sorry, I give up. You have been told so many times now, STRING.FORMAT WILL NOT MAKE YOUR FOLD BOLD, BIG, RED OR ANYTHING ELSE DISPLAY WISE

Sorry to say that isn't the answer to your original question. All you did was reiterate, with a very specific line of code, what's we've been telling you all along. ANd that is that you can only do what you want when rendering the string.

Well, I'm glad I bothered to come back and check on a couple of the older forum messages. You are personal ban list of users to help anymore.

You still don't comprehend what string.format does and is in no way shape or fashion related to Graphics.DrawString.
Also, using a method such as drawstring to render the graphics was suggested to you in the very first response by Dave; but you didn't bother to put 2 minutes of research into it, else you wouldn't be wasting time trying to write insults to those who tried to help you.
Cheers.
