Re: If I link in files (DLLs, GIF-images, etc) into my executable, how do I then access the files?

You can build a dll for you messagebox and just add reference to it whenever you need it. Then you can just use ilmerge or the tool suggested by me to merge dlls and application.

Another way is to include your image as byte[] in your source code and then create memorystream from it. Than you will be able to get the image too. Though I don't like this solution.

I don't like to make DLLs if I don't have to. If I find a bug in my MessageBox in the 10th project I'm using it in, I can easily step through the code and locate bug in the same project. Also, source code is always king when it comes to configuration management. Memorystream seems to be exactly what I was looking for. Thanks a bunch!

Hi all,
One way of displaying map of an area for a gps application is to have simple map image (e.g., jpg) together with geo coordinates of its each corner. since, I am just starting with this kind of application can anyone let me know if there is a better (standard) map file format? I need to display current location in the map and possible navigate user to certain point. the area of coverage is quite small (factory area).
regards,
rnv

Hi,

Refer to the following link:

I hope this would give you better idea to start from.

thank you John,
I already had a look but maybe i missed it..i could not get it correctly. If I have an image of an area (jpg) somehow i should specify its coordinates. is it specified in a separate file from the jpg file itself?
I managed to run map grabber example but it only creates jpg images. where are coordinates saved?

Grouping relevant data together while iterating throug them

Hi There,

I would like to know if someone can assist me with the following:

I need to display data in a tabular format, but I would like to group the relevant data together. In the sample below I am using a asp:repeater to populate a table. The select statement in my code behind file would return data from different employees within different companies ordered by the company name. I want to group all employees from one company together and do a basic summary line before starting with the next company i.e. Number of employees found per company.

<asp:repeater id="employeeList" Runat="server">
   <HeaderTemplate>
        <tr>
           <td width="200">
	        Company ID
           </td>
           <td width="200">
	        First Name
           </td>
           <td width="200">
	        Last Name
           </td>
           <td width="200">
	        Company
           </td>
       </tr>
   </HeaderTemplate>
   <ItemTemplate>
      <tr bgcolor="#ccffff" style="FONT-SIZE: 12px; COLOR: red">
         <td><%# DataBinder.Eval(Container.DataItem,"COID") %></td>
	 <td><%# DataBinder.Eval(Container.DataItem,"FIRSTNAME") %></td>
	 <td><%# DataBinder.Eval(Container.DataItem,"LASTNAME") %></td>
	 <td><%# DataBinder.Eval(Container.DataItem,"COMPANY") %></td>
      </tr>
   </ItemTemplate>
   <FooterTemplate>
   </FooterTemplate>
</asp:repeater>

Thats a bad start.

You could use IndexOf or regex to help you find any instaces of ')' in your string, then once you've found a ')' you could replace the preceding space with an Environment.Newline

Zip Compression in C#

Hi,

I am looking at a way to do zip compression in C#. Is there any free library that do zip compression as fast as winzip?

Thanks Smile | :)

Check out GZipStream in (System.IO.Compression) namespace[^]. The link page has a C# example as well.

I don't know if that would be as fast as Winzip though. If you need more power, then do have a look at the [Trumpet music here] LZMA SDK[^]

GZipStream is very limited. If you have multiple files, after you archive them with GzipStream you will end up with a single file which has the same name as the archive.

May be, but that's the only thing that the .NET framework has to offer.

So, my other suggestion was the LZMA SDK, which is one of the most powerful compression SDKs (isn't written on managed code though, but can be used from managed code).

Hi Rajesh,

I tried the LZMA, but the compressed file can't be open in Winzip.

Cheers Smile | :)

You can try SharpZipLib[^] not sure about the speed though.

Hi Giorgi,

I have tried this. It is extremely slow for big files. But will try all other people suggestion tomorrow.

Thanks for your help Smile | :)

In .NET 3.0 there is also a ZipPackage Class[^].
Is something more than just a zip file (Office 2007 documents are based on it), but can also be used to manage archive files.

As the prevoius answers, I have no idea about its speed compared to WinZip.

Hi Mirko,

I have tested this class, it is very slow for big files. In fact, SharpZipLib is faster. But thanks though for this info. I have learned something new Smile | :)
