No matter what you do to it, people using the program will have both the data and the code to decrypt it. You can only delay them. However, if you leave it as plain text even the silliest noob could read it (on the other hand, you'd have more to fear from actual hackers, not the noobs)

ha ha ... if you fear about users who uses Reflectors to get strings... DotFuscator would be your option... 
In DotFuscator there is also an option to encrypt string in dlls. 
|
|
|
|
|
That wouldn't solve the problem, nothing would, the problem is impossible to solve
|
|
|
|
|
Ya I agree. Even though using DotFuscator.. It can also be cracked quite easily...
So I think we are thinking too much unnecessarily.. 
The actual author might have already found the solution lol.

Yea you're probably right

On my last project I had to have a Windows Service Telnet into a Unix system, so I had to store the username and password. I stored them in a database with other configuration data. Only users with access to the configuration database would able to see them.

hi dudes,
i want to copy a table from an access database to another table on another access database in windows application using c#,what is the best solution,i dont want my application to hang while copying the data,i will be thankful.
and how can i make a progress bar and relate it to this copy so it will show how much further is needed to be done.u would solve a big problem of mine by answering me,thank u all.

1 - you can do it in another thread
2 - you can show a progress bar, but it will mean making lots of smaller copies, which will slow down the process.

Wouldn't it have to be done row-by-row anyway?
When I copy data from one table to another I use a DataReader.
|
|
|
|
|
Does the table exist in the target database or do you need to create it too?
Are you doing this in a WinForms application? If so, why? I do such things in Windows Services.
0) Open a connection to the source database
1) Get a count of records to copy
2) Use ExecuteReader to get a DataReader for the records to copy
3) Open a connection to the target database
4) Set up a parameterized insert statement for the target connection
5) while ( reader.Read() )
5.1) Set the parameter values
5.2) ExecuteNonQuery
5.3) Update the ProgressBar
6) Close the reader, and both connections

thank u all especialy u pieballconsult for ur solution,the table exists in the destination table,and one more quenstion,when i executereader my select statement for reading from the source table,how can i access each column that is being returned to set it as an parameter for the insert statement?
|
|
|
|
|
dudes i found the ways to access those fields in datareader,so my last question is solved,but iv got a new problem,and that is i have a large amount of records in my database tables,so it would take a very long time for selecting and inserting into destination table row by row.how can i do that by copying the whole table at once,and insert it at once too.i might user dataset and its datatables,but it doesn't work,can anybody give me an example of filling a datatable of a dataset from connection 1,and insert that datatable into connection 2 database? thank u.

hello all
my question is there any method to determine if MonthCalender selected date is bolded or not?
|
|
|
|
|
Data bold means its a part of how you design. If you find it as SelectedDate means the date is already bold if bold is taken for your selection item.

Okay, I bet this question might have been asked dozens of times before, but at the end of the day, I am still confused.
I am working on a charting/plotting application. My application will also have WinForms controls. Please note that I dont want to use third party controls.
Edit: Actually it's little bit more than a simple charting application. I need to plot hundreds of symbols on the plot. Additionally, the plot will be interactive, e.g., selecting, moving or editing the symbols, adding/editing text on the chart itself. Any second opinions?
My current options are:
GdiPlus: Seems best, but does not supports hardware acceleration.
WPF: Practically, its still too slow.
SlimDX: Might be overkill
Tao: Don't know much yet
XNA: ditto
Since I plan to use Windows 7 features in my application, So this will be a blend of WinForms and custom graphics.
Any help or links comparing the above would be greatly appreciated.

Yes, that's just standard 2D C# code
The NULL Developer wrote: WPF: Practically, its still too slow.
It's done using DirectX, so if it's an option, why not use DirectX without WPF, if you want it to be faster ?
The NULL Developer wrote: XNA: ditto
Another technology based on DirectX.
your options are
1 - GDI ( or GDI+ )
2 - DirectX
3 - OpenGL
That's all that exists, everything else builds on one of those.

Microsoft Chart Controls for Microsoft .NET Framework 3.5 (Windows and ASP.NET)
Besides the libraries, get the VS add-on, documentation and massive 200 sample set.
They're great (IMO).
There should be a WPF version around too.

If you are supporting Vista SP2 / Windows 7 and up only, then you might consider using Direct2D[^], a new hardware-accelerated immediate-mode Windows graphics API. You will have to do a bunch of interop but if you badly need the performance it could be worth it.
Otherwise, you should be able to get decent performance out of GDI+ if you optimize well - buffering, batching, etc. If you use System.Drawing you'll have the advantage of being cross-platform as well.
If you don't mind using a non-free solution, there's VG.net[^], a vector graphics library that handles rendering for you, optimizes heavily, and is easy on memory.

Then I suggest going to the jobs board and offering to pay someone to write it for you.
If you want to write it yourself, then my image processing articles might be a good place to start.

My image processing articles are on this site. They will not show you how to watermark a video.

I'm sorry if anyone posted this question before, but i was wondering how can i remove and XML tag, and i mean just the tag not the entire element example:
<font face="Arial">
<font style="FONT-SIZE: 12pt">Un tehnician în munca lui se foloseşte de diverse scule. Aproape orice trusă de scule conţine una sau mai multe şurubelniţe drepte (vezi figura1 </font>
<font size="3">si 7</font>
<font size="3">).</font>
</font>
to become :
<font face="Arial">
<font style="FONT-SIZE: 12pt">Un tehnician în munca lui se foloseşte de diverse scule. Aproape orice trusă de scule conţine una sau mai multe şurubelniţe drepte (vezi figura1 </font>si 7 ).
</font>

This is a tough question to answer without knowing the overall goal of the routine you are trying to write.
If you are just trying to eliminate unnecessary HTML, I recommend using a tool like HTML Tidy.
Writing your own solution to clean up HTML would require a great deal of effort.
If you simply want to remove all instances of <font size="3"> and the corresponding </font> surrounding text from your XML, there are a couple of options:
1 - Load XML into XmlDocument and use XSLT to transform output the way you like. You would have a XSLT template to match font[@size="3"] which would just output the inner content.
2 - Loop through the string, looking for instances of <font size="3"> and build a new string by adding the text between the <font size="3"> and the next </font> tag, eliminating the </font> tags.
My guess is that you are looking to cleanup unnecessary HTML, so I would go with a third party option for doing this.
