I would suggest sending an error report via an email. You don't really have to prompt the user to fill out an email, you can fill it out yourself by using the System.Net.Mail namespace.

And why do you hate using primary key, when primary key is the key to your problem

I think that he actually has a primary key, named "no".

Why do so many write "doubt" when they mean "question"?

Make a query that counts how many records there are with that number. Example:
"select count(*) from SomeTable where no = 42"
The result is either zero or one, which tells you if the record exists or not.

Use Guffa's query he provided you. Just substitute the 42 with the value in the textbox...

Hi,
I developed an application that receives a lot of transactions and generates C# code to perform a dynamic execution in order to create the requested response. The C# code is generated matching the request data with several rules define by the users.
I used some profiler to find a memory leak that were happening with the app. Generating some snapshots I found memory problems with reflection.
When I executable performed the CodeDomProvider.CompileAssemblyFromSource the memory seems to be very afected, It seems that any assembly loaded into a given cannot be unloaded once it's been loaded with .NET runtime.
This kind of programming could work for few transaction per hour, but when it refers to several transaction per seconds this will be a real problem.
Is there someway to dynamically execute C# code and preserve a lightweight execution and good performance?
I was considering developed a parse/compiler because the complexity that could achive the generated source code, but First of all, I want to find out if there is something in C# that already do that?
Generated Code sample: The values of the variables are filled with the incoming transaction data.
" int x = 13, y = 3, z = 200; if ( ((x*y) > z) && (z < 200) && ( x > y) ) return 1;"
Thanks.

While an assembly cannot be unloaded once it is loaded into an application domain, you can create a new application domain, load the assembly into it and the unload the entire domain. I do not know the performance of this only that it can be done.

Hello,
I have a COM+ application built using C# and the MSI for it runs just dandy, its basically a COM proxy for .NET to ASP. However, when running a test VBScript, I get the following message whenever I attempt to execute one of the methods (object seems to get created though)..
on this line: set objCreditAppEntity = objComProxy.GetSavedApplication(1, "CITDE")
with this message: Error retrieving certificate with ID <> from location LocalMachine
and this stack trace:
System.Configuration.ConfigurationException
Stack Trace:
at CIT.EAI.Crypto.CertificateManager.RetrieveCertificateFromStore(X509CertificateStore store, String keyIdentifier)
at CIT.EAI.Crypto.CertificateManager.GetDefaultCertificate()
at CIT.EAI.Web.Security.WseUtilities.GetClientToken()
at CIT.EAI.Web.Security.WseUtilities.ConfigureProxy(WebServicesClientProtocol protocol)
at CIT.EAI.EFCanada.ComProxy.RepositoryFactory.GetCreditAppWS()
at CIT.EAI.EFCanada.ComProxy.EFCanadaComProxy.GetSavedApplication(Int32 creditAppId, String applicationCode)
Any ideas why? seems to be a WSE thing, but I'm lost as I'm still kind of a newbie to COM, etc...This proxy talks to three web services by the way.
VBScript test code given below
----------------------------------------------
Dim objComProxy
Dim arrContact
Dim errCode
Dim objCreditAppEntity
Dim objCreditAppEntityList
Dim objQuoteEntity
Dim objQuoteEntityList
dim xmlDoc, sPath, sFile, sInFileName
Set objComProxy = CreateObject("CIT.EAI.EFCanada.ComProxy.EFCanadaComProxy")
'ERROR HERE
set objCreditAppEntity = objComProxy.GetSavedApplication(1, "CITDE")
WScript.Echo "Credit app ID: " & objCreditAppEntity.CreditAppId
WScript.Echo "Credit app status code: " & objCreditAppEntity.CreditAppStatusCd

I am writing an application in C#.NET. I am using .NET DataBindings in addition to direct calls to the database. My application currently uses SQL Server as the back end. I would like my application to also support MS Access as a back end. I'm having a difficult time getting the databindings to work with either SQL Server or MS Access. Any tips/advice would be greatly appreciated. Thanks

Hi,
I am so sorry for this question. I am sure there are a million answers to it. In fact, I found some articles on it but when I tried running them, I kept getting errors. I think they were for an older version of VS because sometimes it would try to convert them when I load them up. I have done the RSS reader training from MSDN - to give you an idea of where I am regarding my knowledge level.
Here is exactly what I want to do;
I am developing my first non-training related application. It is a simple finance application but I want the user to be able to create the database with the name and location of his choice. I have read book after book and article after article about databases in VS and almost all of them use the wizard to create the database and tables, etc. The ones that don't give me compile time errors. I want the program (under user control) to create the database at runtime. He can either click on a toolbar icon or go Menu/File/New. I can do the form related things but this database thing is kicking me around the block. I looked up create database in the msdn library help and it keeps giving me t-sql commands and scripts but the user will not have sql server installed so I can't do that. It is beyond me why this is so hard for me to find.
Ciao

Use SQL Server Express instead of Access. It's free and you can use the SQL commands you have read about.

um..ok but how do I do that. Like I said, when I tried the examples I have seen like this one (http://www.codeproject.com/cs/database/DBInstaller1.asp), I kept getting errors.

Perhaps you would care to elaborate and tell us what errors. "I kept getting errors" isn't very helpful. How would you solve a problem with level of information?

Firstly, regarding the errors related to loading up the sample I referenced in my last post, they arise from the Visual Studio Conversion Wizard. It does not specify the errors other than saying that there was a conversion error with banner.jpg
Secondly, I think I gave enough information in my original post. If you didn't read it, I will repeat it.

If someone knows the answer, I would appreciate a proper reply - preferably with a snippet of sample code.

First issue. Contact the author if you havne't done so already.
Second issue. Be specific. What have you tried? What are the issues you are having?

Proper reply? It took three posts for you mention the errors were from the conversion wizard and not code related. If you want a "proper" reply, then provide the details necessary for us to help you.
brickbat wrote: preferably with a snippet of sample code.
I find it difficult to believe that after reading all the references you say, you did not find any example of a sql statement to CREATE DATABASE.
