if you have a quesiont about an article, ask the author. If you want us all to try and help, try working out what line has the error, and posting some code. No way could I hope to help you based on this, it's ridiculous.

That is the only article that I have seen on the CodeProject that can do what you are asking, and for that matter, it will probably be the simplest since their is an attached article to the code.

ToolstripButton Image size?

kbalias10-Aug-08 18:59

Hi
Is there a way of changing the actual display size of the ToolstripButton Image? I am not talking about the BackgroundImage.

I can change the size of the ToolstripButton when I make ToolstripButton.AutoSize = false, but it does not matter how big I make the ToolstripButton, the Image size stays 16 x 16.

I have tried getting the Image from the ToolstripButton and change the size and put it back on the ToolstripButton, but it still stays 16 x 16. The size of the image has changed, because I tested it by displaying it in PictureBoxes before and after the resize, but on the ToolstripButton the display size does not change.

Regards.

This question is old, but I was looking for the same information. I finally figured it out.

Set ToolStripButton.ImageScaling = false, and ToolStripButton.AutoSize = false. Then you can use an image of any size and it won't be resized/scaled. You will be responsible to ensure that the image is the right size for your button size.

HTH.

Another option is to set ToolStripButton.ImageScaling = true, and set it's containing ToolStrip controll's ImageScalingSize property to a desired size. You can, for instance, add a 48x48 image to a button, leave the button's ImageScaling property = true, and set the containing ToolStrip's ImageScalingSize property to 24x24, and the image will be scaled down to 24x24 (not the default 16x16).

You will also want to set the ToolStripButton.AutoSize property to true (otherwise, modifying the ImageScalingSize property doesn't seem to do anything.)

HTH.

We have an ASP.NET forum. Using server.mappath to get the root is the only extra step you need to create directories on your server. Of course, you cannot create directories on the client with ASP.NET.

I'm creating a simple chat application so I started programming with the user interface. Ok here's how I did my layout, I have a split container in a horizontal orientation. The panel that is above the split container has a rich textbox where output or messages pops out including the user's messages. The panel that is below the split container also a rich textbox where the user enters the message. Whenever the user has finished typing the message, they hit the ENTER key, and then the message pops out in the rich text box that is above the split container. After hitting Enter, the rich textbox(input) should be cleared out which was not a problem. Here's the problem on that textbox, after clearing rich textbox, THE I-BEAM pointer should be pointing on the FIRST LINE... well it doesn't after I clear the rich textbox it is still pointing on the second line. Is there a command that I can CONTROL the I-BEAM pointer to POINT on the first line? or is there any other way around?

well.. i can't post the full code cause its going to eat the whole page. Anyways, here's a code snippet of what i've done on clearing the rich textbox.

/* 
* assuming the user has pressed the enter key this lines of code
* gets executed. Actually, before this code, the content of the rich
* text box input has already been appended on the rich text box output
* so what i have to do now is to clear the rich text box input and the
* I-BEAM pointer should be pointing on the first line of the rich text box
*/

/* 
* ok this worked, the contents of the rich text box got cleared
* BUT, the I BEAM pointer is pointing on the second LINE of the 
* rich text box input, which is my problem.. Why is it pointing on the
* second line?, BECAUSE this method was triggered by an ENTER KEY.
* So now what I want is a code that will set the I BEAM pointer to
* be pointing on the first line.
*/
richTextBoxInput.clear();

Hi, I am trying to convert some of my BlitzBasic code over to C# and I cant get the following statment to work?

Blitz:
If paletteRmap[i]=0 And paletteGmap[i]=0 And paletteBmap[i]=0

C#:
If (paletteRmap[best]=0 & paletteGmap[best]=0 & paletteBmap[best]=0)

Error Message
The left-hand side of an assignment must be a variable, property or indexer?

Thanks.

You are looking at the wrong operator for the error. The equality comparison operator in C# is ==, not =.

However, you probably want to use the regular && operator that does short-cut evaluation, instead of the & operator that always evaluates both operands, regardless if it's needed to determine the result of the operation.

if (paletteRmap[best] == 0 && paletteGmap[best] == 0 && paletteBmap[best] == 0)

Despite everything, the person most likely to be fooling you next is yourself.

And = & (bitwise 'and')
Or = | (bitwise 'or')
AndAlso = && (logical 'and')
OrElse = || (logical 'or')

You'll get into problems replacing the bitwise 'And' and 'Or' operators with the logical && and || operators. Conversion problems from VB are caused by the fact that many VB programmers misuse 'And' and 'Or' as logical operators (they will function as non-short-circuiting logical operators, but are designed to be bitwise operators).
