Hello,
at the moment i'm working on a Project that keeps a Textbox in sync with all connected Clients.
The problem is when using a Richtextbox after a while it creates a loop in textinput.
I can't find the cause of it.
With a normal textbox everything is fine.

But if I use a RichTextBox the the above-mentioned problem appears.

Hi
Your problem is not clear. if you can provide little more information about the problem.
Like:
What do you mean by loop in RTF?

Yes it is, not clear enough.
OP, could you tell me what you mean by text input?

Hi
first thanks for your help.
The explanation of the loop:
Typing something in the Textbox triggers an event that is sending the written Stuff to the Server.
The Server is than sending it back to all connected Clients.
But sometimes if you type to fast it will then cause all connected Clients to continuously update (sending-receiving-sending-receiving and so on) and the program gets unusable

What event are you handling in order to detect when the (rich) textbox is updated?
Often when hooking into the Changed event or the likes, this is raised both by user input and by changing to the text by code. That means that the user types something, Changed is called, messages are sent and then the code adjusts the Text property. But then, Changed is raised again (this time due to a change from code) and the process repeats.
I'm guessing with a normal Textbox this infinite cycles ends because the textbox eventually recognises that, even though you set its Text property to something else, the actual contents of the Text is unchanged.

Thanks for your answer.
I couldn't manage to find the mistake so i decided to use a ordinary textbox instead of an richtextbox element.

I would like to discuss the process of setting up the Entity framework. It has some learning curves to it and would like to outline the process and share this with others. Help me fill in the blanks and add comments as you have learned it. Realize the object names in the container look just like your tables and fields - so your will not be exactly like the example here.
Most database objects have a Fill method. So how does Entity load the model, with the creation of the Entity Container! Too simple? I think so. If you have not learned LINQ you should it is pivotal to this experience.
Steps:
1) Build you database,
2) setup your tables and relations,
3) setup the server explorer in VS,
4) add the project data source (using Entity),
5) Imports;
Imports System.Data.Objects
Imports System.Data.Objects.DataClasses
Imports <your program namespace>.<your entity name>
6) create the instance of your entity container
Dim model As New DM_dbEntities
Add a new record:
model.Records.AddObject(New Record With {<the fields initialized here>})
Dim rec As Record = Record.CreateRecord(<int id>)
model.Records.AddObject(rec)
model.SaveChanges(<save option>)
That's it for the setup. Feel free to make comments or suggestions!

There is some useful information on it here[^] and here[^].

Thanks for the links. I am more looking for discussion and making a simple outline for people who are new to it as it is very different than normal database setups. I don't even want to get into queries in here, just the setup and experiences people have to share with community. Mainly cause this is where I am, learning it, and have questions about it. Searching the documentation is not as easy of a read either. Thanks again.

Seriously! Can't you see I already made the changes to my first post that outlines the process in a simple and understandable version instead of all the crappy searches. I am not looking for an answer - I have it. So if you have some discussions please do, stop sending links!
|
|
|
|
|
Yes, seriously! Read the link I gave you about how to ask a question.

My definition of discussions and questions seem to be different than yours. Maybe try reading my posts again. Some options left open here are connections and modifying them.
|
|

|

It's not my definition it's that of the site owners, and I think you've been a member here long enough to figure out how it works.

This isn't really a suitable place for this as what you have added here is not a question. Why not make it a Tip/Trick, so that it doesn't disappear when more questions are added to this page?
|
|
|
|
|
The name for this forum is discussions. But thats fine.
|
|
|
|
|
Is it? I can't see that anywhere, but the reason I recommend a tip/trick is that it doesn't disappear from view quickly the way a question can.
|
|

|

That's the only way I can get here is to click on 'Discussions' on the green menu bar. I found the answer while posting here while waiting for some discussion on the topic. I do think I will make it a Tips/Trick thing - thanks.

Ah, sorry. I get you - I always use the menu at the left, so I forget about that menu.

I have a button in my form and on click of that button I am writing this code....
<pre>
OdbcCommand cmd ;
cmd = new OdbcCommand("abc", cn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.ExecuteNonQuery();
I have made a procedure named abc in database which is returning only one row from login table..So i am just checking that on click of that button my procedure should run but while debugging when i come to cmd.ExecuteQuery() it throws following error..
ERROR [42000] [MySQL][ODBC 5.1 Driver][mysqld-5.0.77-community-nt]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'abc()' at line 1.
So plz sort out the problem as soon as possible...

This is not the most polite way to ask for help.
If you look carefully at the error message it gives clear details about where the problem lies, and what you need to do about it.

Your procedure returns a row of data, but you use a method that doesn't return anything with ExecuteNonQuery. Do you see the problem yet?
