• Windows Forms UNC/URL path from OpenDialogForm

  Hi I'm using the OpenFileDialog control in VS .net 2003 to allow users to select file paths and save them into a grid and add a description. Now this works fine for local and network files which can be resolved to a UNC path. My problem is that when trying save the path of a file located on the web with a URL path it downloads the file locally to the users temporary folder and points to that rather then the source path. example: select file at google.co.uk/documents/programming/OFDCode.vb Click Open File is downloaded to temporary folder The .FileName property updated to C:\Documents and Settings\%USER%\Local Settings\Temporary Internet Files\Content.IE5\GHGJGZUP\OFDCode.vb I need the .FileName property to return th ...Show All

• SQL Server Programatic creation of SSIS packages

  I am playing around with creating packages using C#. One major problem I have run into is controlling the location of the tasks I create in the package. I have found no way to access any properties to set this. Does anyone know how to do this Dave, I don't think the ability to define tis exists in the API at the moment. if you think it should then ask for it at Connect ( http://connect.microsoft.com ) I recommend you take a read of this though: Extended properties...

• SQL Server Train and test data sets

  I've seen that sometimes is better to split the table into a test dataset and a training dataset, and I'll appreciate if anyone can explain why is this... thanks Santiago Acenolaza Argentina Usually after you finish building a data mining model, you'll want to test the accuracy of model against sample data. If you use the same data that you used in training, the model might show accurate results; but in reality it might have overlearned (or overfitted) on the data. Splitting the dataset into test and training allows you to validate the model accuracy on dataset it hasn't seen during training, which is more representative of the dataset it'll be used against for prediction. Let me know if you have any a ...Show All

• Visual Studio Express Editions Using a variable to specify a label using ctype

• Windows Forms How to calculate the coordinates of text-entry fields in pre-printed forms?

  I would like to write an application in C# to collect data from users and then print them on pre-printed forms (examples of pre-printed forms: visa application forms, employment application forms, social insurance application forms, etc...). The forms have hundreds of text-entry fields. What is the best way to print the data on the forms I guess I have to calculate the coordinates of each text-entry field to do printing. If so, what approach would you recommend By the way, is C# a good programing language to write this type of application Is there any other programing language that you you would recommend I am pretty new to C#, so I don't mind switching to another language if it's better suited to my need to write the application.

• Visual Basic VS 2005 Commerciral Development Version?

  I work for a commercial software development company and our primary product has been components (.DLLs) developed in VB6. When we started years ago, we had to buy the VB6 Enterprise Edition in order to develop .DLLs that could be distributed and registered on customer machines. Does the same concept exist in Visual Studio 2005 We want to add a line of .Net-based DLL products and currently have VS 2005 - Professional Edition. Is there any requirement to use VS 2005 Team System for developing commercial apps You can use any version of visual basic / visual studio to develop commercial applications (except student version I think) So you could develop applications using VB Express (which is free) if you ...Show All

  hello. I will explain my problem I have an application, in that is a webbrowser and I want it to switch to an url on a user specifiet time. but now.

• Visual C# "Smalltalk’s object-based hierarchy does not work so well".Also c#??

  I read a book , "Thinking in C++".At pg:694( Introduction to templates) he writes: "The Smalltalk solution. Smalltalk (and Java, following its example) took a simple and straightforward approach: You want to reuse code, so use inheritance. To implement this, each container class holds items of the generic base class Object (similar to the example at the end of Chapter 15). But because the library in Smalltalk is of such fundamental importance, you don’t ever create a class from scratch. Instead, you must always inherit it from an existing class. You find a class as close as possible to the one you want, inherit from it, and make a few changes. Obviously, this is a benefit because it minimizes your effort (and explains why yo ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Model Animation

  I was wondering if there is any example code for model animation floating around yet I'm basically looking to do a simple walking animation via an .x file. I scoured the XNA documentation and was surprised to not find anything on this topic yet. From what I understand, it appears that the .X processor only loads static models. Your basically on your own to create a custom processor to store the data into your own animation storage format. Are there any plans for providing builtin support for basic animations (With the builtin XNA model processors) in the RTM Maybe I'm clueless and this process is more straight forward then I'm thinking. Looks like leclerc9 just posted what I'm looking for in the XNA Framework forum : http://f ...Show All

That should shed some light on what the problem is :) Also, you may have made changes in the web.config which is stored in your applications web directory. You could rename this file and see if it makes any difference. ...Show All
