Opération inter-threads non valide : le contrôle 'buttonConnect' a fait l'objet d'un accès à partir d'un thread autre que celui sur lequel il a été créé.

Hi,
I'm not good in french but I assume you are accessing some property of buttonConnect from another thread. Have a look at Control.Invoke to resolve this.

Hi,
generally those are two different abstraction layers mainly doing the same thing. When trying to decide which one to use you should at first look for which one a driver for the target db is available. In the case of Oracle you could use both. If I remember correctly OleDb was faster, but this only matters if you fetch large amounts of data from the db.
If you know you are using Oracle and you also know you will never switch the database engine than have a look at ODP.NET[^]. It's an implementation of the common ADO.Net interfaces which comes directly from Oracle and is (naturally) faster than the other two. It also has some more Oracle specific functionalities. The biggest drawback is that you can only access Oracle with it and nothing else.

Hi All,
I need your expert on the following issue.
We are working on designing a portal in .Net, which will be deployed at multiple locations. (US and Europe)
The purpose is software distribution (upload and downloads).
All updates will happen through an intranet portal (publishing of a new software product/patch etc). This need to be replicated with all other deployments (US and Europe etc).
Publishing of software includes uploading the software (installer) and related information (description etc).
This involves 2 things.
Transferring the software product file (installer). This might be huge one.
Updating the data base with related information.
If anyone has thoughts or worked on similar assignments, Please let me know. I am interested in knowing the best practices in this area.

I'm changing some code in an existing program and when I rebuild I get the maximum errors have been reached (102 or something like that). Can I change this number? If so where? I'd like to get all the errors so I can fix the "easy" stuff first.
|
|
|
|
|
102?? I doubt you can change this. If you've got 102 errors, you've got more serious problems than changing that limit. It sounds like a good re-write is in order.

That's actually what I'm trying to do. Making it more OOP but I had variable calls all over the place that didn't have declarations. This is that monster program where one function has over 5k of lines.

|

Oh God, I feel for you! But, Guffa is right. Start at the top and work your way down. There is no setting to change the max number of errors in the list.

 The largest function I ever had to deal with what where one developer created a function with about 1.5K lines. It was an override of the Render method in a web control and much of it was copy and pasted from other parts of the web control. After a few days of refactoring I managed to get the method down to about a couple of hundred lines and I'd created about a dozen other methods of a couple of dozen lines each that the main method called repeatedly. After all that I was totally exhausted and I still hate that class and am only glad that the client never asked for any modifications in that area.

Most of the errors that you get are probably related to other errors. If you for an example have an error that makes it impossible for the compiler to create a specific method, you will also get an error everywhere that you use that method.
Start at the top and fix the errors, and you'll see that the list of errors will quickly get shorter. If you start in the middle of the list you will only find that you can't fix most of the errors, as they are related to previous errors.

I create a txt file which name xx.txt, then I execute the WebClient.UploadFile to upload the file to the server side. The file was uploaded successfully but few lines of header and footer was added to the original context of the file. Please see the example bellow.
-----------------------8c8883ecf24ad9e
Content-Disposition: form-data; name="file"; filename="xx.txt"
Content-Type: application/octet-stream
Context of the txt file
-----------------------8c8883ecf24ad9e
if the uploaded file was jpg, ... format, the system will not be able to reopen the uploaded one because of this header, please advice

I am not sure of what you are expecting. it looks like you need to set the content type properly.
well, refer to the following web links for some info on the similar topics.

Please don't write whole sentences in bold.
A single question mark is all that is neaded to mark the sentence as a question. Multipe question marks have no meaning at all, other than informing everyone that you don't know how to write.
Open the properties for the project. Go to the Build tab. In the Output section you will find the "XML documentation file" property. Check the checkbox and verify that the generated file name is what you want.

hey folks,
can anyone tell me if it's possible to alter a enumeration or a class during runtime? for example adding an item to a enumeration or exchanging a method with another?
if not, what can i do to customize the host application with a 'add-in' which is loaded by the host application?
thanks for hints

Specify an interface for the add-in, then create a library with a class that implements the interface. Now you can load the library dynamically, and use the interface to access the object without having to use reflection for everything.
