If you are asking how to get the text out of the TD, then use the innertext property of the TD. Make the TD "runat=server" and give it an ID.

Data access layer code generator , Reccomendations ?

Andrew Torrance9-May-07 3:22

There are many data access layer tools , so I do not know where to start . I just want to get out of repetitive boiler plate coding . But I have a few requirments:-
1) Works with MsSQL . ( Virtually all should)
2) Produce C# code (Again - all should)
3) Must produce a data object that maps onto a row of a table .( This has been the stumbling block)
4) The data object must have no references to any DB/connection . I.e pure data . Maybe a few Ctors , ideally a struct , but if a class must support ICloneable .
5) Icing on the cake is if the data object overrides = in order to make a value comparison ( I know MS advise against it but its useful).
6) Collections of the data objects would be nice

Why the 1:1 row to object ? Well I found over the years that if I put all my effort into a normalised DB then the code almost falls into place if I produce a 1:1 row - > object . Then I use an object that maps to a table or stored procs in order to communicate with the underlying tables . Not haveing any reference to the DB in the data object means it is as light as possible in the GUI

DataTable to Excel Worksheet fst!

Guten Tag,

If I have an excel Worksheet instance say sheet1 and a DataTable instance dt1, how do I add a row to the sheet1 row by row instead
of iterating to each row and iterating to each cell within that row in the dt1? I want to be able to do this because it seems it would be faster as such. 5K rows of 20 columns each takes about 12 minutes saving to an excel file in my machine using the latter method.

Thanks for any guidance.

I think you should use some screen recorder, which can help you capture whatever streaming video and audio files on your screen, and it can help you record full screen. If you want to get the video to standard video format, it also can help you capture video to avi, so that you can export it to your portable device or upload to some video sharing website.

How to generate a shorter encrypted string?

HI!

i am generating a license key for my software. i am using System.Security.Cryptography.TrippleDES encryption technique.

i am generating a 25-digit random number and a 25-bit string which represents the features of application.

First i am interlacing both strings and then encrypting them using TrippleDES algo. But the encrypted string which is returned by the function Encrypt(), i.e. also my license key is more than 150 characters long, which is ofcourse too long for a license key.

Can any one give me idea how can i generate a shorter license key, about 25-30 characters long...should i change the encryption algo or do something else...?

Thanks in advance..

Regards,
Affan Ahmad Toor

You can store the key in a file and which can be read by your program, it could be a flat file or an xml file. I have seen a few companies use this technique to send long encrypted licenses.

Hi!
thanks for reply...

Do you know any way to do it?

Thanks in advance...

tag clouds for C#?

Don Rolando9-May-07 1:30

9-May-07 1:30

Hi everyone!

I am searching for a tag cloud control. Is there something compareable available as source, or would I have to do this completely on my own?

So far I only found source that generates HTML, but I would like to use such a cloud on a form, so I prefer GDI+ drawing instead of markup output. Poke tongue | ;-P

I tried on my own a little bit, but it looks kind of ugly - depending on the tags it shows. Animating it in sense of slowly changing the single priorities flickers and leads to line-jumps in my implementation, argh.
I have not found the perfect algorithm to arrange tags always on the same place so it looks good even when they reach maximum or minimum size. Frown | :(

And public available algorithms always focus on markup output instead of sizes or areas where I could draw my tags in.

Hints are welcome, example implementations would even be loved. Big Grin | :-D

If I should find some additional time and it results in a super tag cloud for C# I will let you know. Wink | ;)

Well, you are right in that System.String is class. But how you say it is... um... System.String is CLI built-in type/class. string is C# specific alias of System.String

I didn't vote but someone probably found your answer confusing. Smile | :)

"String" is the class and "string" is the alias name of the String class.

I think I am right.
