Hi everyone,
I am new to code project , sorry if i place the question in wrong area. I am struck by a problem while using threads. In my windows project I have MDI form and shows different forms in the MDI form.In one form i am sending mails. i am sending the mails in a separate process using threads to enable the user to do anything in the application while sending the mails.one progress bar will appear in the mdi form status strip, when mail is sending.
When user clicks the Send button in the form i make it disable until the mail is sent.Before calling thread i make it disable and after completion of thread's work i make it enable, it works fine. but my problem is, When user opens this form and send mails, if he visits another form and again comes to this form i am checking in the form load whether thread is going on, by check whether progress bar is visible in the mdi form , if it is visible i make the send button disable. I need the send button enable after thread completion, i make it. but it is not working. the send button is still disabled.I don't know why it is happening. if user remains in the same form it is working fine. if he visits another form it is not working. I am using thread invoke method for using the controls. but still the problem is there.
Please any one help me
Thanks in advance.
Rajesh.

Hi,
threads can't access Controls directly, only the main thread can. You need one of two things:
1. use the Control.InvokeRequired/Control.Invoke pattern (search for InvokeRequired in CP articles)
2. or use a BackgroundWorker instead of a Thread; that one has InvokeRequired built-in into its ReportProgress and WorkCompleted events.

apparently not. you did something wrong or didn't tell an essential part of the story.

I want to build a new windows distributed application (server/ Client). The client (.NET envoirnment)will be at a remote place outside the city (at any place) that shall be able to interact with the server for saving or retrieving data. On the server side the same application will be performing same tasks as the client side on LAN. There will be layers such as GUI,DAL,BLL(Bussiness logic), Controller and Data Types
1. Is it possible to have a same windows application at both sides (client and server )as i am presuming it to be?
2. What mechanism will be used for transporting data between the server and client
will it be a static IP address and http or something else i dont know?
3. Windows remorting or Web services will be useful for that?
i hope it will not bother anybody to help me.New to dot net so wanted to share and recieve ideas thanks
Thank every helper

Hey All,
I am experiencing a strange issue, i have built and tested my RegEx in Expresso but when I call it from my code (C#) I am not getting any matches. If i step through and grab the values from the variables and put those in Expresso it works ....
RegEx:
<br />
Lead\sID\sNumber:\s*(?<LeadNumber>[^\r\n]*)(?:\r\n)+<br />
Prospect\sName:.*(?:\r\n)+<br />
Prospect\sContact:.*(?:\r\n)+<br />
Prospect\sPhone:.*(?:\r\n)+<br />
Marketing\sCampaign:.*(?:\r\n)+<br />
Prospect\sInformation:\s*(?:\r\n)+<br />
===============\s(?:\r\n)+<br />
(?<Company>[^\r\n]*)(?:\r\n)+<br />
(?<Address1>[^,]*),\s(?<Address2>[^\r\n]*)(?:\r\n)+<br />
(?<City>[^,]*),\s(?<State>[^\r\n]*)(?:\r\n)+<br />
(?<Country>[^,]*),\s(?<Zip>[^\r\n]*)(?:\r\n)+<br />
Contact\sName:\s*(?<FirstName>[^\s]*)\s(?<LastName>[^\r\n]*)(?:\r\n)+<br />
Contact\sPhone:\s*(?<Phone>[^\r\n]*)(?:\r\n)+<br />
C#:
<br />
MatchCollection myMatches = Regex.Matches([Text], [RegEx], RegexOptions.Multiline | RegexOptions.IgnoreCase | RegexOptions.Compiled | RegexOptions.IgnorePatternWhitespace | RegexOptions.CultureInvariant);<br />
[Text] = the body of an email
[RegEx] = the above pattern
Any input or ideas would be greatly appreciated.

Hi,
I would debug such beast using "binary search", i.e. throw away half of the search specification, and keep doing that until something matches. Then you know the problem is in the part you last removed.
OTOH I would never come up with such a complex Regex pattern in the first place. It is just unreadable. And what happens if someone somewhere decides to add/delete a space, a new line, whatever to the e-mail format?
IMO you need several smaller operations to extract the fields individually, your code looks like a maintenance nightmare to me.

Hello Luc,
Normally i would agree with you 200%, however this is a subcontract project which is going to be used by other developers. They wanted me to allow for configuration of the email parsing by having a setting which contains the RegEx to use.
You can find the solution to my problem here[^], i didn't want to keep cross posting.
Thanks again for your input.
If at first you don't succeed ... post it on The Code Project and Pray.

Is it possible (and how) to make an user control with a panel and make it a container (so that I can drop other controls on it at design time?
Or if it is simpler
If i place a button on the usercontrol - what do i need to do so i can click it at design time?

Yes it is possible. A thread here[^] has the same thing as you need.

Hi Feudalac,
In addition to the thread that d@nish just referred you to, Henry Minute was inspired by that thread to publish an article here on CP exactly addressing this problem.
Designing Nested Controls[^]
I participated in that thread, and also illustrated one way to do this for one single usercontrol containing one container object, and you could, in theory, combine any number of these one-container-per-usercontrol objects at design time, but Henry's solution went far beyond mine in terms of practicality : his solution will let you do the same with multiple containers on one usercontrol.
best, Bill
"Many : not conversant with mathematical studies, imagine that because it [the Analytical Engine] is to give results in numerical notation, its processes must consequently be arithmetical, numerical, rather than algebraical and analytical. This is an error. The engine can arrange and combine numerical quantities as if they were letters or any other general symbols; and it fact it might bring out its results in algebraical notation, were provisions made accordingly."

Hello all,
My crystal report contain hyperlinks to the Event Video file (i.e..avi files).
Its format is somewhat like -
"EventVideos/EventVideo_" + {DataTable1.EventId} + ".avi"
As I create hyperlink at design time, it remains active for all the events. But the case is that my all events do not have Event Video associated with it. So, such events also have hyperlink for event video which is not expected.
To avoid this, I have to delete or disable the hyperlink for such events.
My question is - Is it possible to delete or disable the hyperlink at runtime in Crystal Report? If yes, can you please explain me how?
It will be great help. I will appreciate it.
Thanks in advance.

In the DataSources Window, if you expand your Employee node you will see an EmployeeDetails node right at the bottom. It is this EmployeeDetails node that you should be using.

Try working through this tutorial[^] as a new solution, so that you can get a better understanding of the process, then come back to your project and try again.
Please come back with more questions if you still have problems after doing that.

I'm not sure I'm in the right group for this but I'm trying to develop a program or better yet get one that's a blackjack game simulator that over million hands etc and give me the wins or losses statistics of my systems over time. It's easy to get a blackjack simulator but not one that over million hands etc and give me the wins or losses statistics of my systems over time.
Thanks in advanced for any suggestions.
