• Windows Forms CheckBox Checked

  Hi there I have a class that derives from Checkbox and is basically a toggle button. I also have the ability to group the class instances so that they behave a bit like radio buttons and reset the checked state of any other buttons of this class on the form. Trouble is, changing Checked to false also triggers the CheckedChange delegate. Can anyone think of a way to temporily stop the CheckChanged event from firing from with the class itself. To explain a little further, the class has a method ResetChecked and this sets Checked to false, but in doing so it fires the CheckChanged delegate. I can't remove the delegate and add it after because I just can't find a way to do that Any ideas anyone Thanks Dave Si ...Show All

• .NET Development Secure FTP through proxy server

  I tried using the FTPWebRequest object to do a secure FTP download through my proxy server. However, with the proxy object set correctly and EnableSSL=true, when I execute the getResponse method I get an exception of "SSL cannot be enabled when using a proxy." I will likely be using a production server that is behind the firewall and will thus need to communicate through the proxy server. Is there a .NEt way to do secure FTP through a proxy server I could use the IPSwitch ws_ftp program to do it, but don't want to go through our purchasing process if there is a simple way to do this with .net code. and how do you get trough a firewall my problem is that I want to run my ftpUploadApp ...Show All

• SQL Server Howto impersonate code to use specific role in SQL2005

  Hi there, in SQL2000 Analysis Services I used a very complex script to authenticate as a specific user/role to create offline graphs and Pivot-Table pictures via script for users concerning their own security rights. I read out the role of this user and used the security settings within this role to filter the owc-element so that the user only gets to see the elements/data he is allowed to. This was necessary since the script (DTS) was run with administrative rights and therefore had access to all data. I built a serverside OWC, applied the security-filtering, exported to excel or picture and sent it via email as subscription. now for the question: Is there any way to tell a script to use a specific role when accessing the c ...Show All

• SQL Server Mirror goes down... Affect client transactions?

  If the mirror server goes down for any reason, then what happens to client transactions against the principle Will any client transactions fail Thanks in advance Quick answer - no, they should not be affected. However, if you have witness set-up and the principal cannot connect to both the witness and the mirror then it will stop serving the database and the transactions will fail. Take a look at this article: http://www.microsoft.com/technet/prodtechnol/sql/2005/dbmirror.mspx#ETPAE Thanks, Kaloian. ...Show All

• .NET Development Fatal Flaw in the Large Object Heap?

  Hi All, After playing with the GC I find the following interesting. The problem domain I typically work in requires the allocation of very large arrays for image processing. We have discovered some issues when our processes are long running. We run out of memory and can not reclaim it. Our only recouse is to restart our processes. In an effort to discover why I uncovered the following: The LOH (Large Object Heap) is never compacted. I think this is a fatal flaw in the GC. I understand MS stated reason for this, but shouldn't there be someway to compact the LOH if necessary, at least a method call that forces the issue Does anyone know of anything that can be done Any workaround is better than killing the process... Here is a demo ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Save As for an entire project?

  Greetings! When I create a new project in MS Visual C# Express, a full set of folders (bin, obj, Properties) and files are created. I'd like to be able to "source" my projects, but can't figure how to use Save As so that Express will create new folders and files using whats currently open, just with a new name. Hope that makes sense. Thanks! You have a few options, but the easiest would be what Jim said. Anytime you want to version your code, just navigate out to the folder above your project, CTRL-CLICK, DRAG and RELEASE the folder. Rename the copy to comply with your naming standards for versioning and go back to work on the original. All done. Other, more complex options, include ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. I have to write an article about XNA Game Studio : user point of view needed

  Hello everyone, I have to write a dossier for a french videogame monthly magazine, where I should present the "product" to the readers, most of whom are teen gamers. It's no tech article, but a "perspective" one, about what is and may become XNA. If it can spark something inside a few of our readers, and have them try game development, that will be nice. Therefore, I'd like to have an idea about XNA reception on the users' side . I have a serie of generic questions. I'd be really happy that some of you cared to answer. Basic questions : - Why choose XNA over DX C++ dev - Why or how is XNA more suited to indie/homemade developements - Is there a reason why one would choose not too dev How would you describe XNA framework, refering to - th ...Show All
