Contact Crystal for a redistributable product license key.

I'd offer more information than that, but I wasn't the one that had to deal with Crystal Reports the last time we completed a project using it. It looks like you need to add the redistributable to your deployment project and add a custom property with the license key details.

Start by eliminating the possibilty that it is user related. Take a copy of the file and see if you can delete manually but using the same user that will the code runs as. If this works and the application still cannot delete another copy of the file, then it has to be code.

We would then need to see some source to find out why it doesn't work.

I believe this has to do with default security measures on .NET assmeblies. Microsoft turns on some security by default and some security policy may restrict this operation.

Problems with Exception Management Application Block

Andy Hochstetler5-Nov-03 16:06

5-Nov-03 16:06

I'm having difficulty getting the Microsoft Application Block for Exception Management working. In particular, I'm trying to customize the DefaultPublisher so that it uses a custom log source in the EventLog.

Here are some of my constraints, many of which I've overcome.

1) I wanted the assembly deployed to the GAC so that more than one app could share it.

2) My apps are web apps, so I had to deal with security issues regarding getting a custom log source set up.

OK, so I created my strong names for the ExceptionManagement and Interfaces assemblies, and got both installed to the GAC. No problem. I used the INSTALLUTIL.EXE to run the custom installer for the ExceptionManagement assembly.

So far so good. I manually created the registry key and string value for my log source.

Next, I set up the web.config file. Here's the way I had it set up the first time:
<configSections>
<section name="exceptionManagement" type="Microsoft.ApplicationBlocks.ExceptionManagement.ExceptionManagerSectionHandler, Microsoft.ApplicationBlocks.ExceptionManagement" />
</configSections>
<exceptionManagement>
<publisher assembly="Microsoft.ApplicationBlocks.ExceptionManagement" type="Microsoft.ApplicationBlocks.ExceptionManagement.DefaultPublisher"
logName="Application" applicationName="My App Log Source" />
</exceptionManagement>

Now when I generated an exception, several were logged using my custom log source, including several that it was unable to find the type for the section handler. Well, I figured out that it was because I had an assembly in the GAC and hadn't fully qualified the names.

So I fixed the web.config to be:

<configSections>
<section name="exceptionManagement" type="Microsoft.ApplicationBlocks.ExceptionManagement.ExceptionManagerSectionHandler,Microsoft.ApplicationBlocks.ExceptionManagement, System, Version=1.0.1404.32518, PublicKeyToken=d16c1e31f52ae760, Culture=neutral" />
</configSections>
<exceptionManagement>
<publisher assembly="Microsoft.ApplicationBlocks.ExceptionManagement"
type="Microsoft.ApplicationBlocks.ExceptionManagement.DefaultPublisher, System,
Version=1.0.1404.32518, PublicKeyToken=d16c1e31f52ae760, Culture=neutral" logName="Application" applicationName="My App Log Source" />
</exceptionManagement>

Well, now to the point I'm at now. I get an internal exception that has the following detail. I'm at wits end! Any help would greatly be appreciated!!!

Thanks,
Andy

DoEvents kill Callback - Help needed!

Vacationistas5-Nov-03 9:07

Vacationistas

5-Nov-03 9:07

I'm using the callback function of RASDIAL (RASAPI32.DLL). It works just perfect: The RASDIAL call returns immediately and my callback function is called numerous times to process the progress/error messages. In order to wait for the successful connection, I wrote a WHILE-loop in my main class to wait for the "Connected" message. That's where I'm having problems: the Application.DoEvents() in my WHILE-loop causes a System.NullReferenceException followed by message telling me that there is no source code available at the current position. I learned that the DoEvents call is for single-threaded programming and I guess that the RasDial callback function probably introduces multiple threads. I found a workaround by using a Timer without DoEvents() but then I find myself left in the Timer-Event to go on with my app. Summary: I WANT TO USE DoEVENTS() or something equivalent! Can someone please help me out?

private void btnRasConnect_Click(object sender, System.EventArgs e) {
ras = new Dialup.RASDisplay();
uint retCode = ras.Connect(""); // RasDial with callback
if(retCode != 0) {
ras.DisplayRasError(retCode);
} else {
string tmpString = ras.GetLastMessage();
while((!tmpString.StartsWith("ERROR:")) &&
(tmpString != "Connected") &&
(tmpString != "Disconnected")) {
Application.DoEvents(); // **** causes abort in unknow module
tmpString = ras.GetLastMessage();
}
}

Beginner's Localization question

I'm starting an application with Managed C++ with windows Forms. I know how change the current Culture and since this action every resouces that open take the new Culture Value( System::Threading::CurrentThread::CurrentUICulture = new Globalization::CultureInfo (String * IdCulture) (...) )

OK that's right, but what happens with the Main Form that is Loaded since the start of execution?
Can I do a Reload or something like that, by anyway, or assing dinamically another ResX File to the MainForm for translate it without Close()?

Thanks gurus, I expect your answers Big Grin | :-D

You can't change the locale of a form once it is loaded. You have to create a new instance of the form with the new locale.

If you are really slick you could copy the original form, but with the new locale, and use the transparency set to 0. Once everything is in place you can fade it in over the old form, then remove the old form - This would be so nice from a UI perspective - no flicker of changing forms and a really obvious but subtle change occurs.

How to use Memory-mapped files in .Net?

what is the cleanest way of dealing with memory-mapped files within .Net?
Looking for a way to port a large library code that makes heavy use of memory-mapped files.

Any pointers would be appreciated. Thanks.

From what I've read, you'll have to wrap the Win32API calls yourself and probably make use of Unsafe code in your application to get this working.

Memory Mapped Files are not directly supported in .NET ...

How to Use 2 connection objects in a single sql statement in c#

I like to get help for the below sql statement.
I use two oledb connection objects to connect to 2 different sqlserver - DB's.

NewSQL = insert into sample "(SELECT * from sample1)

In the above "insert" statement the table 'sample' belongs to one conn-object and table 'sample1' belongs to another conn-object.

can anyone give me the solution.

thankyou
kaling

Re: How to Use 2 connection objects in a single sql statement in c#

Colin Angus Mackay3-Nov-03 2:06

Colin Angus Mackay

You cannot use two connections in one SQL statement in .NET. The SQL statement goes in one Command object, which is attached to one connection.

I am assuming you are using SQL Server 6.5 or previous (otherwise you should really be using a SqlConnection and not an OleDbConnection)

I am assuming this is not a one time operation. There are better solutions for copying data between two databases than this.

Okay - A solution (note: I didn't say "THE solution", just "A solution")...

Create a data reader to suck out the data from sample1. On each Read() iteration create an insert command to inject a record into sample.

Another solution may be, and I say "may be" because I've never tried it, to use a fully qualified table name: server_name.database_name.owner_name.table_name

I hope this helps.

Another possible solution to do this is to create and use data VIEWS. Simply create a view that combines data from the two SQL servers, and then query agains it.

Hi All,

I am into webdevelopment with ASP, .NET and stuffs. I am running my PC with XP OS. Can I maintain the same ot shall I change to 2000 Adv Server?

The problem here is I cant run SQL server 2000 with full server option.

Please suggest me... to be or not to be with XP?? I have plans to go for the 2003 server later (after 6 months)

My dev box has Windows XP with IIS and the developer version of SQL server installed for tests and sample projects. Real projects run off our Windows 2000 Server (not advanced) box with SQL server installed. Our hosting boxes are also Windows 2000 Server and they work fine.

Remember you can run SQL server on a non-server Windows installation if you have the developer edition.

I dont have it, thats the problem. So, I prefer to go for the Server 2000 as you said... may be 2003 some days later (its not right time for me. I would experiment with the 2003 with some one else PC in the office, and then give it a try to my PC Blush | :O

)

Thanks.

If it's just for your development machine, take this route ...

Download the MSDE 2000 SQL Desktop engine from Microsoft's site for free MSDE 2000[^]

Following that, you can then download a new GUI front-end, if you feel the need for such things, like this one MSDEGUI[^] that was developed by Christian Graus here at CP.

Any .Net Framework install problems?

Douglas Troy31-Oct-03 5:48

Douglas Troy

31-Oct-03 5:48

My superiors have recently asked me a question regarding the .NET framework, raising concerns about installing it on client machines running Windows 98, NT, Win2K machines. They want to know how we, as a company, can go about testing said framework for compatibility issues. They wanted assurances that installing the framework on these machines, wouldn't disrupt or cause other applications, not using the .NET framework, to fail, or for Windows itself to fail.

Since I obviously cannot answer these questions, despite having super mind reading powers and the ability to see into the future Roll eyes | :rolleyes:

, I thought I'd ask the great CP community to share your experience(s).

Any of you run into any "real" problems installing the framework? Has the framework itself caused any PC to just STOP working? If so, did you figure out why? Any issues with other, non .NET, applications?

I'm going to take the information provided and build some kind of an "FAQ" or Trouble shooting guide, so real problems and solutions would be great; and I'll gladly share that combined information with anyone wanting it.

Thank you,

D.
