Hi,
After building my C# solution (using Visual Studio 2010), my debug folder (bin/debug) includes some assembly file (dll files, and .exe file).
Then I tried to use the obfuscator software (such as: Dotfuscator,..) to obfuscate my files successful. Then, I add these assembly file to my setup project, and build it to create setup package.
But, after installed my setup package, I tried to use decompiled softwares to check assembly files (in the installation folder), I still could see and get origin codes.
Do you know why ? How can I obfuscate my assembly file for setup package ?
Thank you for your help !

Hi,
I use this to change the back color of a cell:
private void dataGridViewData_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
if (!string.IsNullOrEmpty(e.Value.ToString()))
{
e.CellStyle.BackColor = Color.LightGoldenrodYellow;
}
}
This works, but also check box cells are changed if they are checked or not.
How can I make an exception for check boxes, or is there an other way to do this?
The datagridview is set to autogenerateColumns = true.

One way to distinguish columns is to check the ColumnIndex property of the DataGridViewCellFormattingEventArgs object.
For example you can access the actual column being formatted using
dataGridViewData.Columns[e.ColumnIndex]
For more info, refer to DataGridViewCellFormattingEventArgs[^]

Hi,
I've already been there, but I wanted something simple.
Have it working now, this is what I use:
private void dataGridViewData_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
int x =e.ColumnIndex;
int y = e.RowIndex;
if (dataGridViewZakdata[x,y].GetType() == typeof(DataGridViewTextBoxCell))
{
if (!string.IsNullOrEmpty(e.Value.ToString()))
{
e.CellStyle.BackColor = Color.LightGoldenrodYellow;
}
}
}
Thank You for your efford,

You could test the DataGridViewCellFormattingEventArgs.DesiredType property. It will be typeof(string) for textbox cells and typeof(bool) for checkbox cells.

Thanks Alan,
Now I have it for both types in two lines:
private void dataGridViewData_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
if(e.DesiredType==typeof(string) && (!string.IsNullOrEmpty(e.Value.ToString())))
e.CellStyle.BackColor = Color.LightGoldenrodYellow;
if(e.DesiredType==typeof(bool)&&((Convert.ToBoolean(e.Value) == true)))
e.CellStyle.BackColor = Color.LightGoldenrodYellow;
}
Edited: I did not test it thorough, if I insert a new row in database I get an exception:
if(e.DesiredType==typeof(bool)&&((Convert.ToBoolean(e.Value) == true)))
Object cannot be cast from DBNull to other types.

My goal is to parse out a company name and contact name that is the actual filename of the excel spreadsheet.
I will use this information in a sql server 2008 r2 database to obtain other related information for the company and contact person.
My problem is the file name is manually keyed in my the user who runs the sql server 2008 r2 reports (ssrs) on the standard edition.
Is there away you would suggest that I try to parse out the company and contact name from the file name? There are delimiters between the company and contact names how the delimiters may change.
(Note: I am intending on using this method instead of opening up the excel spreadsheet to
obtain the information I am looking for. I think that there would be alot of C#.net code that is required to open the excel spreadsheet and get the data I am looking for in certain rows and columns. If obtaining the code from an excel spreadsheet is not so bad, can you show me the code on how to accomplish this goal?)
Can you show me in code and/or point me to a reference on how to accomplish my goal?

You need to provide more detail, such as what the filenames look like, and what the delimiters could be.
|
|
|
|
|
Easiest way will be either to use string.Split on the file name (if the delimiters are sensible) or a Regex:
For example, if the file name was "2012-12-31 Oranges (Jaffa Co, John Smith).xlxs" The I would use a regex:
(\((?<Company>.*?),(?<Contact>.*?)\)) Would match it and extract the company and contact as separate fields.
If you get an email telling you that you can catch Swine Flu from tinned pork then just delete it. It's Spam.

The file name would look like the following:
C:\\app1\12_2012\customer name_contact name.xls.
The part of the file name I listed above is the following:
customer name_contact name.xls.
The customer name can contain all kinds of special characters like (,),'. Thus I need to be able to parse out the customer name with all the special characters.
Note: It is my idea to have an underscore between customer name and contact name for the following reasons:
1. I need some kind of a delimiter,
2. I do not think alot of people's name have an 'underscore' as part of the name.
3. The underscore is a valid character for a filename.
Note: these names may like like the following if it is entered incorrectly by a user:
customer name _ contact name.xls.
Thus can you tell me how you would parse out the names in that case?
|

|
|

Try:
<pure lang="c#">
string inp = Path.GetFilenameWithoutExtension(path);
string[] parts = inp.Split('_');
parts[0] is the company,
parts[1] is the contact.
If you get an email telling you that you can catch Swine Flu from tinned pork then just delete it. It's Spam.

Hello,
I have a .props(Project Property File), which is currently executed using a bat program(?Windows Batch File).
I want to rewrite this using Asp.Net.
How do you call a props file in ASP.NET, console application?
This is just one part of the program, which is being completely re-written in asp.net from asp.
Thanks!!
|
|
|
|
|
The same way you execute a batch-file, using the Process class.
|
|
|
|
|
Thank you!
Kind of new to asp.net.
Do you know where I could a list of all the classes avaliable in .Net?
Thanks again!

Assuming the BCL (Base Class Library), it's documentation can be found on MSDN[^]. You could create this list using code by using "reflection". Search this site for examples

The SEHException class handles SEH errors that are thrown from unmanaged code, but that have not been mapped to another .NET Framework exception. The SEHException class also responds to the HRESULTE_FAIL, which has the value 0x80004005. (Source here[^]).
It'll be impossible to say what goes wrong without seeing the actual code. And no, it's not urgent here; we're volunteers.

Thanks Eddy, I can not study more about the constructors and their properties and many more.
But the problem is that I was working on this particular project, then I went on break for 2weeks. When I got back to work, I now experienced this Exception. So I'm wondering what could be the challenge. cos the the program was working perfectly ok before
Thanks for ur support

Code is always executed in the same way; if nothing changed, then one can expect the same result. If the result changed, something else must have changed too. If it's not the code, then see which "Automatic Updates" have been installed.
Further, the exception will be thrown at a specific location. You could take that constructors' code and post it here. Being a generic exception, it's impossible to tell what's causing it without debugging.

Thanks alot Eddy...I have learned alot from the experiences you have shared wit me. Now, I observed that when I run my Visual Studio IDE I don't get the SEHException error message again. Everything runs successfully. But my login to the application is disable; I cannot access the database again...
I will be sending the page code to you
Kindly help

That's a weird side-effect. Any exceptions? Can you login to the database manually?

It's easier to post the relevant code here, using PRE tags.
