Hi
I am using VS2008 C# with datagridview and filling the cells using a byte[].
Is there a away the cells will display the value in HEX ?
Thanks
Have a nice Day

Register for the CellFormatting[^] event and do the conversion for display there

A simple method like this should do it:
public string ToHexstring(byte[] byteArray)
{
if (byteArray.Length > 0)
{
StringBuilder resultBuilder = new StringBuilder();
foreach (byte value in byteArray)
resultBuilder.Append(value.ToString("X2"));
return resultBuilder.ToString();
}
else
return "00";
}

The mear fact that a number is being displayed in the DGV makes the item you see in the DGV cell a string, no matter what the actual data type is. So, no there's no way of displayed any data in a DGV without converting it to a string, or some other custom rendered display.

how to cut,copy,paste a picturebox control in c#.net at runtime, can u please provide code for this.

Don't repeat the same question over and over.

Now, as to answer the darned question;
A PictureBox is a place-holder for a picture, in the same way that a label is a placeholder for text. Both don't have the cut/copy/paste functions, because they aren't editable.
A Textbox is the placeholder for text that can be edited. There is no placeholder for editable pictures.
In other words, what is supposed to happen when you "cut" something from the PictureBox? Should it remove the entire picture, or just a selection thereof? The first "cut"-mechanism is easy to implement, as you just need to assign "null" to the image of the picturebox. The second "cut"-mechanism is harder to code.
What about "paste"? Do you want to insert a new picture in the picturebox, or do you want to combine the picture with what you are pasting?

.dat is typically a generic file extension used to denote that it is an internal format for some application. We cannot know the format unless we know the application to which it belongs.

You can open the file using a FileStream and a BinaryReader, but you'll need to know how it is formatted internally to be able to interpret what you get back.

True.. I managed to get the format from the database designer.
Thanks Colin! And congrat's on being an MVP again!

I had very little experience with creating setup projects. If i remember well, the Publish tool from VS creates a MSI file, that installs the application, but does not allow the user to specify an installation path or other options. This is called Click Once deployment, right?
What I need is an installer which will allow the user to specify an installation path. What do you recommend? (preferably free). Thanks.

What about the Setup Project already in Visual Studio?
|

Hmmm, if that does what I need I should start learning how to use it. I somehow had the impression that Setup Project was doing the same thing as the Publish Tool. Thanks.

Scroll down on this page[^] and you'll find some useful stuff from MS.

As Colin said, use the one built into Visual Studio. If you're using an express edition which doesn't have this, there's always Inno Setup[^].

I use the NSIS install system. NSIS Sourceforge Page.[^] It's fairly easy to script a decent setup. And FREE.

Hi Guys,
I'm redirecting the output of an external process to a function which writes the data to a log file using StreamWriter.Write() method.
Is there a smart way of limiting that file size?
Thanks!
Eyal.

Try log4net. It can automatically create new log file when an old one exceeds the size you specify.
|
|
|
|

I'm assuming that the OP wants a log file that will never get larger than size N, and that older entries are deleted as necessary. Creating a new file seems to me to be a sloppy workaround.
I can't think of any way to do this other than to load the entire file into memory, delete what makes it too large, and then save it again.

I second. Look for RollingFileAppender class and the RollingStyle property.
My suggestion is to create separate logs for each day/week/hour/whatever and to delete the logs older than the x-th version.

We can get the size of file through FileInfo. Hence, we can decide whether to create a new log if the size is out of limitation. Such as
FileInfo fileInfo = new FileInfo("1.rar");
if(fileInfo.Length > 100*1024)
{
//create a new log file
}
