Hi everyone
I developed a software but somehow (by mistake to be honest) in the beginning I used MS SQL Compact Edition
the system works fine, but I know that compact edition is very limited than Sql Server 2005
According to my algorithm, every entered record creates several tables.
This works good.
But I'm a bit nervous about latter stages
Does this Compact Edition has a table cap?
for example, after 5000. table created, does the DB gives an error like "DB table quantity limit reached" or sth like that?
I know it sounds ridicilous but I've encountered numerous ridicilous errors since I started this project

Hi,
I've been googling a long time about this, so I thought you peeps might have an answer for me.
I have a application which has been written in .net1.1 a long time ago. I ported that application to .net2.0 (one step at a time  ) and left the code the same as much as I could. Everything works, except one thing which I cannot figure out why not.
I have this service, which is listening on a port on the same server as the client runs on. My client in this case is a configuration editor with some basic functionality like getting the time the last synchronisation ran etc.
The service is called the StatusPublisher.
I initialize the the publisher object for use with this call:
*****.IStatusPublisher publisher =
(*****.IStatusPublisher)Activator.GetObject(typeof(*****.IStatusPublisher),
string.Format("tcp://localhost:{0}/StatusPublisher", servicePort));
This is the call which works in .net1.1 but fails in .net2.0:
string returnValue = publisher.NextRun (serviceId);
This call locks up the complete config-tool, kinda forever (killed it after 50 minutes). I had a logging step between every code block, but the logger before the publisher.NextRun() logged fine, everything after was a complete lock up.
Any idea why I can instantiate the publisher object but cannot call a method from it?

I can't help you there. I Have search on MSDN and can't find any info on IStatusPublisher. I only can presume that it is not shipped with .Net Framework. If you or your own company is author, then investigate, or contact a technical support on official forum or to author/company

It's one of our own clases which is an class implementing MarshalByRefObject. It's actually quite the same as MarshalByRefObject only adding some methods.
internal class StatusPublisher : MarshalByRefObject, *****.IStatusPublisher
{
public string NextRun(string serviceId)
{
}
}
Thing is, I can load this class, but I cannot call the methods on it. So it must go wrong higher up the chain, which is .Net code I think.

have you tried removing Internal keyword?
Or tried add public in front of class?
Is this class a DLL?

You need to explain what it is you are trying to do, and what your problem is.
No one will write it for you, but if you have specific problems people will be happy to guide you to the answers.
Post some details of the bit you are stuck on.

i do not know c# but i know c++. we are given this project to challenge the we as students. so i need to find the code that recharge the pay phone when you enter the pin voucher then show you the amount you have been charge with
. and as you enter the phone number should establish the connection. i mean just like the mobile phone.

Sorry, like I said, no one can help you without a proper description of of the problem, and no one is going to just write all the code for you.
Try and do it yourself and the ask specific questions when you get stuck.

Then this should be very easy.
Bokang Selialia wrote: and as you enter the phone number should establish the connection
So you need to write code to actually recharge a real phone and make real phone calls ? Or do you mean a simulation ? If the latter, you can't know C++ very well if you can't do it. Either way, you're refusing to post code, which means we can't really help you with it.

Some observations
1 - if you think we can correct your code without seeing it, you give us too much credit
2 - we don't care when your homework is due. That's your problem. You've been given the resources needed to do it, and it sounds like a trivial task. If you were to post code and a specific question, someone might decide to help if it seems like you need a little bit of advice. But what you posted is utterly worthless, because we're not going to do your homework for you, and we can't correct code we can't see.
What sort of course lets you choose between C# and 'nedbeans' ?

11 days and ticking, if your teacher has any regard for comments, organization, proper coding I'd say you're as close to failing as you're going to be, well, you know, not including the point at which you actually fail.

So you have a choice between C#, which is a language, and nedbeans which is an IDE. Not very clever. C# or Java then maybe.
Bet you get the same enthusiasm to help from a Java forum.
Eleven days to go is a poor show when you are still undecided what language to use. Better get cracking if you still care about passing.
When you decide and hit a code problem I'm sure many people will be far happier to assist.
If you have knowledge, let others light their candles at it.

And how are we to know what that even means? You are asking us to write code for you without a clue as to what you are trying to do.
Even if we knew what you was trying to do, we won't write the code for you. Try rentacoder or on the jobs board.
Why is common sense not common?

I'm working on C# windows forms project using the glass aero effects available in Vista and Win 7, and getting the glow behind text effect using DrawThemeTextEx as per the code below. All works fine with normal aero glass, but if I add some colour to the glass (I'm using LinearGradientBrush) the rectangle around the text is transparent does not include the colour painted with the brush.
I've done a bit of searching and reading, and it appears that CAPTUREBLT is designed to deal with this, but as mentioned in the Miscrosoft documentation it doesn't work properly with DC, which is what I'm using here.
My question therefore is is there another way of adding text using DrawThemeTextEx that will include painted layers?
<br />
public void DrawTextOnGlass(IntPtr hwnd, String text, Font font, Color forecolor, Rectangle bounds, int iglowSize, TextStyle textStyle)<br />

How would one search for a unicode string written like: ...A.D.J.S.F...
I need to be able to searched typed text with the dots in between so search ABC as .A.B.C. and find the starting offset of that, then replace it with something else like 123 converted to .1.2.3..
I am somewhat new to C# and computers so I may have said some things incorrectly, sorry.

Given that you're new to C#, why do you find yourself having to understand unicode at this poin ? Where is the string coming from ? Where is it going to ?

There are a few things I want to do and I'm not sure where else to start besides doing things I want to do with C#. The string ABC is coming from textBox1 and needs to be in the format .A.B.C. Not sure what that is but I think its unicode text, and I need to search for that string in the file and then find the starting offset for it, then have the string of text 123 in textBox2 for example converted to the format .1.2.3. And then have that string replace the amount of characters equal to its length at the offset output from the first part.

Why does it ? The user has to type it in like that ?
krt72012 wrote: . Not sure what that is but I think its unicode text
No, it is not. Well, all .NET strings are unicode, but the dots don't change that, or define it.

OK, this is sounding like homework then ? You're taking a class ?

I guess you have to know more about exactly what I'm doing but when I search for a text sting in a hex editor as a unicode string, the string has dots in between each character. What I'm trying to do is search for a halo 3 service tag written in that format inside an xbox 360 profile based on what the user puts in as their service tag, and then have it search and find and replace the service tag with what the user enters in the second text box.

krt72012 wrote: but when I search for a text sting in a hex editor as a unicode string, the string has dots in between each character
That's because Unicode characters have two bytes and you're looking on the byte level. However, inside a textbox, in .NET, the string is unicode and it's shown just as a string. That is, the A has two bytes to represent it, but you just see the A.

Ah - OK. Well, if you're in .NET, it will show as unicode. Then you can use File.ReadAllText to read a file, the Replace method on the string class to replace the text in textbox1 with the text in textbox2, and File.WriteAllText to overwrite the file in it's changed format. If the two strings need to be the same length, you'd need to validate that, and of course, if the text entered is so simple that it appears elsewhere in the text to where you WANT to change it, that will be changed as well. In that case, you'd need to use the Find methods to find the actual index and do some work with the substring method to build your new string ( or the replace method may take parameters to specify where in the string it's allowed to look )
