If you don't have a solid enough foundation in encryption to know the answer you should not be writing code that does encryption, from a security standpoint. It is very easy to make mistakes that can compromise the data. If it is truly important information hire a specialist to come in for one day to do it for you or your company. If the data is not that important just do whatever is simplest and don't worry about it.

As for checking whether is exists in both languages. The documentation for both languages provide that answer.

Thank you for all your answers.

As you can see I don't have a solid foundation in encryption, the data I am trying to encrypt is not so vital and sensitive. But it should be encrypted. I can even use Base64 but it would be a little bit too easy I guess. Smile | :)

Base64 is not encryption at all. It is an encoding to make sure 8-bit data can safely traverse a 7-bit path.

ToolStripPanel Drawing

I am trying to get a ToolStripPanel to have the same drawing style as the embedded ToolStrips, so that it looks like one continuous bar. I have the ToolStrips using the ToolStripProfessionalRenderer so that they are styled the same as the Windows Task Bar.

I have gotten close by creating a new Renderer derived from ToolStripProfessionalRenderer:

class CustomRenderer : ToolStripProfessionalRenderer
{
   protected override void OnRenderToolStripPanelBackground(ToolStripPanelRenderEventArgs e)
   {
      base.OnRenderToolStripPanelBackground(e);

      LinearGradientBrush lgb = new LinearGradientBrush(e.ToolStripPanel.ClientRectangle, this.ColorTable.ToolStripGradientBegin, this.ColorTable.ToolStripGradientEnd, LinearGradientMode.Vertical);
      e.Graphics.FillPath(lgb, e.ToolStripPanel.ClientRectangle);
   }
}

This creates the gradient look with the correct colors, but they do not match up quite right. It seems as if the gradient has a higher number of colors, so the spread is drawn out longer.

I have accounted for the border of the ToolStrips (which is not shown in this code), yet they still don't match up quite right.

Anyone know how to make this happen?

I would use excel with macros to do something like this.

At any value change in the datagrid field, you may raise events and invoke the function to update affected datagrid fields.

Hi, ive been using the Digital Persona SDK for past projects but for the scale of an upcoming project I am looking for a better SDK.
Has anyone had experience with different ones and which one would you recommend?
It doesnt need to be free.

Thanks

It just needs to reliably check fingerprints against a database of about 1000 or so. Only needs to run on windows, and must come with both authentication and enrollment functionality.

The SDK's I've used for "large scale production environments" (MUCH greater than 1,000 users) all came with their scanners and will not work with other scanners.

SQL Connection dropping

I have a series of strongly typed datasets in my .NET v2 project. When I shift the project to .NET v3.5 the system runs the first connection but refuses any further connections giving me a Named Pipes error...

I thought that there were no code changes required to migrate from v2 to v3.5, well obviously there should have been because it no longer works, but what should I be looking for?

Any ideas?

Thanks

Make sure your connections are properly released. Also, make sure that your application accesses the database in a linear manner. Then make sure that SQL server is properly configured, etc. Your error, unfortunately, has many potential causes. The current project I am working can be built in 2.0 or 3.5 and access the database without an error so it can happen seamlessly depending on your code.

There must not be any code changes while migrating from 2.0 to 3.5 as framework core(structure) remains the same retaining all previous functionality. All the enchancements are additional to the 2.0.

Looking for a spesific control

I saw a control in a program written in VB which is very easy to adjust time and I am looking if it is possible to find the same control for csharp/vs2008. I couldn't post the picture but it's like this: "00:00" Every zero is divided into 2 parts from the middle with a horizontal line and clicking the bottom piece decreases and top part increases the numbers.
do you know such a control?

That would be a customized control. You can do that yourself, infact even better and easily with 3.5
