Any idea how to do this with the System.Windows.Forms version of the DataGridView?

hello.
how are you all.
"How to Access signature of a file or how we can get information from Header of a file", through which we can compare it with other file to find its diginity.

Can you explain this better please, do you want to identify the file type from byte patterns or simple compare files? What do you mean by diginity?

To be blunt, that is your job, we help with specific problems relating to C#, you create the solution (with probable problems, which we help to fix).

hello.
how are you all.
i am working on my final degree project in these days and my project is antispyware.
in antispyware, i am to use signature base scanning technique. for it i need algorithm for implimentation. i am still unable to find such algorithm or sample source code which can help me in my project.
will anyone can help me to solve this problem. if some one know about it, please send as soon as possible.
thank you

If it's your final project should you...I don't know...actually do it yourself?

Hi Mahmood
Maybe you should have a look at the ClamAV - Project at Sourceforge.net
(http://sourceforge.net/projects/clamav).
It is written in C and is based on a pattern-technology.
You might know, but an antispyware application means a lot of work for you.
Good luck with your project

Hi,
I have a header file with some constants, e.g:
#define PRODUCT32_BUILD 4
#define INTERNAL_VERSION 1
#define INTERNAL_RELEASE 2
#define INTERNAL_SUBRELEASE 3
#define INTERNAL_BUILD PRODUCT32_BUILD
...
Then I have a C# project with class 'AssemblyInfo.cs', with informations like this:
// Appears as 'Assembly Version' and 'File Version' in file properties dialog box
[assembly: AssemblyVersion("0.0.0.0")]
...
What I need is to find a way, how to use the constants of the header-file to change the information in the 'AssemblyInfo.cs' of the c# project. So the result after the build will be : [assembly: AssemblyVersion("1.2.3.4")]. The 'AssemblyInfo.cs' must be changed before the build runs. Start with something like a pre-build and then build?
Regards Daniel

Is the header file a C# file because that code will not compile, C# seems to only allow you to define symbols and not the C style macro replacements.
I'm guessing that that header file is for another part of the project written in C++ or another language and you want to use that header file to define the assembly version of the C# project, am I correct?
I just tried something like this: [assembly: AssemblyVersion(System.IO.File.ReadAllText(@"temp.txt"))] to see if you could write a static class that would parse the header file but it returns this compile error: An attribute argument must be a constant expression, typeof expression or array creation expression.
So it looks as if you can't do it directly in C#.
The only possibility that I can think of is if you create a small program which parses your header file to extract the version information and then inserts this into the AssemblyInfo.cs file and run this program as a pre-build event.
Hope that's of some help.

Hi Ed,
ok, it seems, that there is not an easy way to use this header file in c# project. You are right, the header is from c++ and it is used for all other c/c++ projects. My colleague gave me already an advice how to solve this : I have to make an managed c++ project, which will have just one class and will include this header file. And this c++ project will be used in the c# project...
So far thank you. Ragards Daniel

That won't change the version number, unless you write the C# project in the C++ project, which would mean that it's not a C# project  . I.e. the C++ project would have it's own assembly versiona and the C# would have a different version. (Since VS.NET does not support projects containing, for example C# and VB code or C# and C++ code, you have to seperate them into different projects).
I'm pretty sure of that anyway.
If the other suggested method works then use it but I still think that writing a simple parser would be more flexible, reliable and a better use on resources. (It could even be done in a Batch file but since you've got .NET on the development machine then it'd be simpler to write a .NET executable).

Apparently (in VS 2005) you can have C# and C++ in the same project - provided that the base project is C++. No idea how you do this though!

In the .net 2005 it is possible to have a c++ and c# projects in one solution  . But to write .net exe and run it in the pre-build event is probably a better idea. I will try both. Regards Daniel

Hi @all,
thank you for your support. Finaly we decided to make a 'Global Assembly Info' class. This class will be added to all c# projects (as a link), which need to use global versioning infos. This class is defined as static and has only public static constants:
internal static class ProductInformation { [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Performance", "CA1823:AvoidUnusedPrivateFields")]
public const String Product = "Product name...";
...}
This constants are used to modifie the assembly-versioning attributes in the particular c# AssemblyInfo.cs like this :
(using namespace of 'Global Assembly Info' class...)
[assembly: AssemblyProduct(ProductInformation.Product)]
[assembly: AssemblyFileVersion(ProductInformation.Major + "." + ProductInformation.Minor + "." + ProductInformation.SR + "." + ProductInformation.Build)]
...
The 'Global Assembly Info' class will be filled manually, and not from the 'Versioning.h' as it was planned at the beginning.
Regads Daniel

hi all,
i place a savefiledialog from toolbox on my form.
with a button click i want to save only 'xls files' with some value (lets say 'x') in the first 4 rows of that excel file.
how can i do this ?
help please.
thanks in advance,
bye.
ps:
saveFileDialog2.Filter = "Excel Files (*.xls)|*.xls|" + "All Files|";
saveFileDialog2.FilterIndex = 1;
saveFileDialog2.ShowDialog();
if (saveFileDialog2.ShowDialog() == DialogResult.OK)
{
MessageBox.Show("The Save button was clicked or the Enter key was pressed" +
"\nThe file would have been saved as " +
saveFileDialog2.FileName);
}
else
MessageBox.Show("The Cancel button was clicked or Esc was pressed");
> what else should i add the code above to be able to save a document ?
> i have to double click on 'save' button to close savedialog. why? how can i do that with one click ?

It should be one click, try changing
Mehmet Fatih Akbulut wrote: saveFileDialog2.ShowDialog()
to saveFileDialog2.ShowDialog(this)
Which shows the dialog box as a modal child of the current form, it might be that or you may have to make sure that Main in your project has an STAThread attribute applied to it (if you forget this I know that the FolderBrowserDialog does wierd things, maybe the SaveFileDialog class is the same).
Regarding the saving of Excel files you'll need a component or class that can read and write Excel files (you could use the COM Excel component or use a managed one such as Aspose.Excel[^] but you'll have to buy that I think.

hi all,
i have a datagridview view with 4 columns. (2 int32 and 2 double fields)
at bottom i want to add a new row and type 'TOTAL' in 1th and 3rd columns.
(2nd and 4th columns will contain total values.)
but since 1st and 2rd columns are int32 type, i cant insert some string ('TOTAL') in them.
is there a way to do this ?
help please ...
