HOW CAN IT BE ACHIEVED? what are the complication? how will the iis server handle it, and the ms-sql server handle it .....will there be network congestion... somebody please share the idea..... thanks in advance modified on Monday, December 31, 2007 6:27:28 AM Re: request simulator WillemM31-Dec-07 1:32 WillemM 31-Dec-07 1:32  There are free loadrunners on the internet that can help you generate the load you need. However I can't tell what the server will do, this depends totally on how effecient the application is and how wel equipped the server is in terms of hardware. WM.

Running .NET application from Server Share peterchen30-Dec-07 23:41 peterchen 30-Dec-07 23:41  I'm at the old "Running .NET application from Server Share causes a security exception[^]" Is the state of the art still "You HAVE to fiddle with the local security policy"? I expected that it would be possible to get the generic XP security warning, and let the user continue, but I can't find any.

Then I just send out a link to the .application file (file://server/share1/Support/Apps/MyWonderful.application). This works pretty well, and lets you specify what permissions you want your application to have. "On one of my cards it said I had to find temperatures lower than -8.

How to make the toolbutton or toolmenu image backgroud to be the same with system background? Seraph_summer30-Dec-07 23:20 Seraph_summer 30-Dec-07 23:20  I want to make the background of boolbutton images to be the same with system color. How can I do? By the way, what does mean "ImageTransparentColor" property in VC#? thanks. Re: How to make the toolbutton or toolmenu image backgroud to be the same with system background? Skippums31-Dec-07 7:47 Skippums 31-Dec-07 7:47  ImageTransparentColor is the color within the image that will NOT be drawn. So, for example, to make a bitmap where the only thing visible is a single black dot, make one with a single black dot over a magenta background. Then set the ImageTransparentColor property to magenta, and it will not be drawn. This is used so the images don't have to fill in a rectangular area when drawn. I beleive this answers both questions. (to make it system color, simply set the ITC property as described above, then set the container's backcolor property to the system color).

For example I am creating code in code-behind FileUpload uploadDataFile = new FileUpload(); In Browse dialog I want to restrict File Type as Xls, txt, CSv.

It's not possible with FileUpload control. You can check the file extension and content type after submitting the form. All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia My Website | Ask smart questions Re: How to restrict file type in one or more dynamic file upload controls PIEBALDconsult31-Dec-07 15:41 PIEBALDconsult 31-Dec-07 15:41  What would be the point?

Check to see if object is being referenced Winkles30-Dec-07 22:34 Winkles 30-Dec-07 22:34  I have a tricky problem that I could really use some help on. My app works with a number of very large float[] arrays that can easily use more memory than is available. To solve this I have created a memory manager that, in cases of dwindling memory, will dump some of the older arrays to temporary files. My app can request a reference to one of these arrays at any time, and the memory manager will recreate the array from the dumped copy if it's no longer in memory. The problem is that my memory manager must not dump to disk any arrays that are currently being used by other parts of the app because a) any further changes to the array won't be reflected in the dumped copy, and b) dumping an array to disk that is being kept in memory by other parts of the application won't help memory load to begin with since the array won't be collected. How can my memory manager, when it is deciding which arrays to dump to disk, check to see if other parts of the application are holding references to any of the arrays? Thank you very much!

[my articles] Re: Check to see if object is being referenced Stevo Z30-Dec-07 22:53 Stevo Z 30-Dec-07 22:53  exactly. impelment same mechanism as COM object use. add two methods: AddReference() ReleasReference() and increase, decrease number of it's references in prive variable: int referenceCount. When AddReference() is called, referenceCount == 0 and array is dumped to file, recreate the array When ReleasReference() is called and referenceCount == 1 , dump array to file. Call AddReference() everytime you need to pass reference to another variable Call ReleasReference() everytime you dispose this reference zilo Don't tell ME, I know that!

An issue is that the app reached a quarter million lines of code and a fair level of complexity before it became clear that temporarily writing these arrays to disk would be necessary. Being able to figure out a way to do this that is transparent to the rest of the app would be a real lifesaver.

Winkles wrote: a quarter million lines of code What's a line of code? Anyway, yeah, you need a class that does all that behind the scenes, sounds like a good weekend project. Or make some type of database? So all the arrays are always cached to disk?
