DataGrid Insert Row dubor9-Jan-04 10:31 dubor 9-Jan-04 10:31  Hi, i'm working with a datagrid and I want it to be updatable, but i dont want the last row ( insert row) to be available to the user, how would i proceed? Re: DataGrid Insert Row Mazdak9-Jan-04 10:41 Mazdak 9-Jan-04 10:41  One way is set the AllowNew property of DataSet's DataView to false. Mazy No sig. available now. Files and Sockets Guinness4Strength9-Jan-04 8:51 Guinness4Strength 9-Jan-04 8:51  I've written a window form that send files via a Socket using RSA encryption. I split the file up into peices for sending, I was wondering if there is a generally used buff size for sending over sockets. Right now i split each file up into 100 pieces unless a size is specified by the user. That was mostly for testing, so now I need to set a buffer size to use...any thoughts on the suject ? Whats too big for a socket connection, whats too small ? Re: Files and Sockets Kentamanos9-Jan-04 9:08 Kentamanos 9-Jan-04 9:08  Someone please correct me if I'm wrong, but I think it's like this. Take a look at "MTU". It determines the maximum size of a single packet. In TCP, you don't really have to worry about losing anything, but I think it's more efficient to send it based upon the MTU size. Normal MTU for ethernet is 1500 bytes from what I understand. I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf. -David St. Hubbins Embedding referenced DLLs Den2Fly9-Jan-04 8:27 Den2Fly 9-Jan-04 8:27  Regards buddies, While referencing a .DLL file in my project may I set it as an embedded resource so only one executable assemply be my result? Thanx --- "Art happens when you least expect it." Re: Embedding referenced DLLs Guillermo Rivero9-Jan-04 8:37 Guillermo Rivero 9-Jan-04 8:37  Yes you could do it. But then how are you planning to get the types from the embedded assembly ??? Right, using Reflection... Free your mind... Re: Embedding referenced DLLs Den2Fly9-Jan-04 9:16 Den2Fly 9-Jan-04 9:16  You mean at runtime? .NET framework doesn't provide ability to load types from the embeded assembly at runtime in some way? (I don't mean using Reflection API which requires developer to code, some automatic reference to inside assembly as if it was an external .dll) Would you give more describtive explanation? --- "Art happens when you least expect it." Re: Embedding referenced DLLs Guillermo Rivero9-Jan-04 9:33 Guillermo Rivero 9-Jan-04 9:33  I don't really know how are you planning to do so. I thought Reflection will be your solution. If you know about another way, please let me know about it. Thanks Free your mind... Re: Embedding referenced DLLs Den2Fly9-Jan-04 10:02 Den2Fly 9-Jan-04 10:02  No I don't You are right I guess Reflection is the only way but I can't figure out how to and using which Reflection methods reflect types inside an embedded assembly, can you help me on this buddy? --- "Art happens when you least expect it." Re: Embedding referenced DLLs Guillermo Rivero9-Jan-04 10:31 Guillermo Rivero 9-Jan-04 10:31  Sure I can. Can you send me the code you've done ? and explain me exactly what you want to do ? Free your mind... Re: Embedding referenced DLLs Den2Fly9-Jan-04 20:32 Den2Fly 9-Jan-04 20:32  Ok though I really desire to, but it's not my own code and a team project so I am not allowed. any way I am so thankful about your care and help --- "Art happens when you least expect it." Re: Embedding referenced DLLs Guillermo Rivero10-Jan-04 8:38 Guillermo Rivero 10-Jan-04 8:38  I didn't know about this http://www.codeproject.com/script/comments/forums.asp?forumid=1649&select=709838&df=100&fr=34.5#xx709838xx[^], and it seems a good approach. Do some test. Compile your code normally, including your DLL as embedded references. On deployment, only install the file that contains the emdedded references, and see what happens... Free your mind... Re: Embedding referenced DLLs Heath Stewart9-Jan-04 13:00 Heath Stewart 9-Jan-04 13:00  This is not practical. The CLR loads Types based on their assembly name (filename, version, culture, and public key token) and loads the Type from the namespace and class name. If you set it as an embedded resource, the CLR can't do its job and JIT'ing your application will fail! There's nothing wrong with an app that has references to DLLs. Fusion - the part of the Framework that binds assemblies - either pulls DLLs from the application directory or another configured private path (see <probing> in the .NET Framework SDK documentation), or from the global assembly cache (GAC). If the application is deployed from the Internet/intranet using a touchless installation, it will just as easily download the assemblies in the same manner to the temporary assembly cache and load the executable just by clicking a link (or for an embedded user control). No install is needed (besides the .NET Framework) and you can simply copy files, hence "touchless deployment".   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Re: Embedding referenced DLLs leppie9-Jan-04 14:14 leppie 9-Jan-04 14:14  Its quite possible and not too hard, just a bit of work to get it going. 1. Compile dll. 2. Set dll as embedded resource to exe. 3. In main you need to setup an eventhandler to AppDomain assebly resolve event, cant remeber the exact name now. 4. At the event, read the resource stream of the dll (using compression mite be handy), into a byte[]. 5. Load the assembly via Assembly.Load(byte[]). 6.

Re: Embedding referenced DLLs Den2Fly9-Jan-04 20:38 Den2Fly 9-Jan-04 20:38  Firts of all here is my version of Dell 3Xi as your merry b-day gift: "Art happens when you least expect it" Happy birthday Leppie! Secondly your approach seems great, but may I use refrences to the dll's types and methods inside my code at develop time in this approach? Thanx --- "Art happens when you least expect it."

Main Form Gary Kirkham9-Jan-04 8:21 Gary Kirkham 9-Jan-04 8:21  Is there a way in .Net to get a reference to the applications Main Form (Window)? Similar to what you would do in a MFC app: AfxGetApp()->GetMainWnd(); Gary Kirkham A working Program is one that has only unobserved bugs I thought I wanted a career, turns out I just wanted paychecks Re: Main Form Alex Korchemniy9-Jan-04 10:16 Alex Korchemniy 9-Jan-04 10:16  In your startup method (main) just change it to be like this: form = new MainForm(); Application.Run(form); Where "form" is a static field that you can get to from anywhere.
