Re: How to sync Data of 2 c# projects?

That would depend on your requirements. Personally, I like to use a separate database for the Windows application, which would be a local data cache, which can periodically update the main database. This way, if there are any connectivity problems with the Windows application, the users can still carry on.

Hope this helps.

Hello,

Thanks alot, got a big idea on what you said Smile | :)

I forgot that it might cause trouble if I use only the database of website.
Would you mine if you could give some link about wcf services for my asp.net website.

Thanks,
DAN

Not able to see the dll which is registered successfully in cache

You could start with this MSDN article about Hosting and Consuming WCF Services[^]. I leave the rest to you. Good Luck.

I have created a class library called TestCOM.dll and build the solution successfully and even though I created the application in different directory, I just copied the dll and put it in C:\Meeram395\TestCOM.dll

Inorder to register the dll, I use the following command
regasm TestCom.dll /tlb:TestCom.tlb /codebase TestCom

I got the message that the dll registered successfully. When I tested in assembly folder, I couldn't see the assembly. So I used the following command again to register:

gacutil /i testCOM.dll

I got the message that "Assembly registered successfully in cache".

But still I am not able to see the same in assembly folder. Not sure what's happening.
When I try to unregister, I am getting an error message assembly file not found. But then, why it is giving successful message initially? Should i do something else.

Thanks in advance,
meeram395.

Can you tell us what version of .Net the dll is compiled against, as .Net 4.0 assemblies get posted to C:\Windows\Microsoft.Net\assembly\GAC_MSIL, while earlier .Net dlls are still posted to assembly folder.

Ok. Thanks very much. I think I am using VS 2010, which is .Net 4.0. Let us confirm

Well, you're going to have to understand the PST file format, completely. You can find the docs on it here[^].

Then you'll have to write your own object model to parse up and represent the parts of the PST file you want to handle. I figure, you've got about 6 months worth of work to do this.

No, there is no API to do this for you, that is, without installing Outlook.

Good Luck!

There's no way you're going to get an example. The project you've picked is HUGE. When I said you've got 6 months of work to do, I meant reading and understanding the file format. You haven't written a single line of code by then, other than small projects to test how you're going to do this.

If you can't write an object model to wrap a small binary file of you're own chosing and format, you've got not hope of completeing a project on the scale of an extremely complicated PST file.

There are no tutorials on this stuff and what you're asking would encompass entire books. That's FAR more information than you're ever going to receive in a few forum posts.

About the best information you're going to get that applies to what you want to do is by studying serialization and writing your own formatters. Google for "Binary Serialization" and start reading. Start experimenting with writing/reading binary files. Write you're own files, add information such as dates, times, data of your chosing, lists of things, whatever, ... Then write the code that's going to read that data and create objects out of it. If you can't do that, forget your requirement of not having Outlook installed.

If you're comfortable with C++, then have a review of this[^] and this[^]. And before you ask, no I can't convert this to C# for you - that would take me far too long.

No.

fixed-Length formatting of String

Hi,
I have a string 'Name' to be shown on auto-complete of Text-box, which is filled with company name from Data-Set. This field could be 5 characters long to 50 Characters long. I have do some string formatting, so that i could restrict its length to 20 characters.

so, as a result "Hello" will occupy 20 characters with rest as space:
"Hello "
Also, "ThereIsSomeTextHereInThisPost" will also occupy only 20 characters after trim as:
"ThereIsSomeTextHereI"

How do i achieve this in C# language.
Please reply. Thanks.

You have string.PadRight and string.PadLeft that can be applied to any string.
See http://msdn.microsoft.com/en-us/library/system.string.padright%28v=VS.100%29.aspx[^].

The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

GlobX10-Apr-11 20:29

I think what the OP is asking is restricting it to a max of 20 characters in length specifically for the auto-complete, so PadLeft and PadRight I think may not be appropriate in this circumstance.

You could use the System.Math.Min function like so:

// the result of the operation on the right will give you the Name as is or truncated
// if it exceeds the 20 character limit
string forAutoCompleteBox = Name.Substring(0, System.Math.Min(20, Name.Length));

This will give you either the first 20 characters of the Name, or the whole Name, whichever is shorter. Did I understand your question correctly?

OriginalGriff10-Apr-11 20:38

Rather than post processing of a text box, which will truncate user input, consider limiting it at the point of entry. This generally feels more natural to users as they do not get typing "thrown away" without them being aware in advance. You can set the TextBox.MaxLength property to 20 characters.

To pad the string to 20 characters, use

string paddedToTwentyChars = String.Format("{0,-20}", myTextBox.Text);

Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

Ravi,

The following does the job simply.

Hope this helps,

Rob

string TwentyChar(string orig)
{
    int len = orig.Length;
    if (len < 20)
        return orig.PadRight(20);
    else if (len > 20)
        return orig.Substring(0, 20);
    else
        return orig;
}
