Hi,
I am trying to write custom grammar to parse oracle statements. Can anyone point me to the right direction.
Thanks in advance.

Could you be a bit more specific as to:
1) what you are trying to achieve
2) what you have tried
3) what problems you encountered.

I want to write a parser that will allow me to take a pl/sql statement and ensure that the statement is correct based on some type of grammer that I will specify.
I have not tried anything yet because I dont even know where to start. I am looking for a resource which I can start using that will help me acheive my goal.
------------------------------------------------------------
1. Parse a selected plsql statement and validate it based on some grammar.
2. I have not tried anything yet because this is completely new to me. I am hoping someone can point me to some resource/documentation/tutorial that will help me acheive this task.

OK, but I don't think this is a technical C# question. I would suggest using Google, or the CodeProject search facility, looking for the keywords 'parse' and 'grammar' as a starting point.

I was hoping it was possible to do this in C#.

Well it may be, but before you can start coding you need to design the structure of your program and the logic of your parser and associated grammar. As I said before, try to search on the subjects you are interested in and you may find that someone has written a technical paper on that very subject which will lead you to a solution. Always remember that CodeProject Search and Google are the first steps in finding an answer.
But don't expect anyone on these forums to write your program for you. We are all working on our own problems as well as answering questions.

I was not expecting you to write code for me. I have googled it and have seen that antlr is one way of going but I wanted to know if it was possible to do this in C#.

Well, as a general statement yes, it is possible to do it (or anything else) in C#. However, your original question was framed in such a way that implied you were asking for a full solution to your problem.

Why not take a look at using ANTLR[^]? It even has an PL/SQL grammar available here[^].

Hi,
Why do I get a funny brightening gradient-like behavior when setting the size mode to stretch a small image in a large pictureBox control??
Thank you.

Snippet from the link:
For all of you who are looking to do a similar feat to what I did, the command is as follows:
rasdial <vpn_name> <vpn_username> <vpn_password>
To disconnect:
rasdial <vpn_name> /d
Thus, in usable terms, my line would look like this:
System.Diagnostics.Process.Start("rasdial.exe", "My_VPN My_Username My_Password");
To disconnect from the VPN, simply use this line:
System.Diagnostics.Process.Start("rasdial.exe", "My_VPN /d");

Can anyone tell me how shall I create a new control a button inside a textbox. The button will have a search(loop) picture I will use it as a lookup control in my application.
|
|
|
|
|
why put a button inside a text box? Surely a control designed to distinguish importance like a group box would serve a better purpose then trying to couple a text box that contains a button?
|
|
|
|
|
Hi,
use Button.Controls.Add() ;-

You have it backwards, he wants a button within a text box, not the other way around.

Take a look at the source code for v 1.1 in this[^] article. The FileChooserLibrary contains a control which enables the sort of functionality you are looking for. It is unfinished, but working, and should give you some ideas at the very least.

Hi
I would like to update the GUI once specific scenario occurs
I’ve application that have GUI and logic layers
At logic layers I have hierarchy classes witch means that class ‘A’ use class ‘B’ that use class ‘C’, etc
At Class ‘C’ I would like to notify GUI (such as update counter edit box) once a condition exist (for example
if ((m_num % 100) == 0))
UpdateGUI(m_num)
I know I can use the event mechanism
Create and register event at class A,B,C and register also the event at the GUI
Is there any other way to call event from very low class to very higher class hierarchy?
I hope I describe my question properly
Thanks

The only other way that springs to mind is to use P/Invoke to utilize the SendMessage/PostMessage API calls. That is a lot of work though, when the Event mechanism is there.

Hi,
with which method do you close the form manualy? did the closing handler stop closing? 
kind regards
|
|
|
|
|
thx, sorry for late reply,
yes i have certain conditions in closing event, based on those condition i am closing my form.
a simple condition is a boolean value, if that bool value is true than i am closing my form.
i think this causes the form not to close when i log off my compuer
how can i solve this, Please?
