VS 2008 TCP Send Files Part II
Apr 14, 2009
OK I was a little hasty in marking my earlier thread resolved... I'm sending a file from my server using the following code :
[Code]...
The received file (in my test case it is a PNG file) comes through corrupted - I'm 99.99% sure its a case of encoding but I've tried various options and in each case when I open the original file and the received file in notepad the files are visibly of the same origin but some characters are wrong in the received file. I'm sure its a simple answer but I can't find it - what am I doing wrong in terms of re-assembling the received file?

I have found a simple UDP project at [URL] which is a project written in VB2003. I have imported it into VB2008 Express edition. I have no problems with the send part of the project. I'm able to send messages to internal (eg. 127.000.000.001) and external (in my case the other device has 192.168.0.100) addresses. Now for the receive part... I'm able to receive messagess sent form the same computer (127.000.000.001) but none of the packets are being received by the aplication if sent from an external source.

i'm developing a server application using vb.net and i'm facing a problem. in fact i have a huge data to send to the client via the socket so i use a loop to divide the data and send each part the problem is that when i proceed with the sending the socket send me only few peaces of the data and loose a big part of it. i tried to flush the buffer after each sending but i didn't find how to do it so i used a system.threading. thread sleep between each socket send. it works when i don't have huge data but it blocks my server when the number of packets increases. is there a solution that would replace the. sleep one without blocking the application?

My VB project is large enough that it requires several files. It was originally developed as a Console App and I created each file as a MODULE. All modules could use subroutines, data structures and constants from other MODULES and everything worked fine. I needed to add basic windowing to the app and this required that the app be converted from a Console App to a Windows Forms App. The main window is Form1 which is not a MODULE but a CLASS. The problem is that some MODULE based functions cannot access subroutines, data and constants that are defined within the CLASS Form1 unless they are incorporated into the CLASS file and this makes the CLASS file very large. If I add a new Class file to the project, it also cannot interoperate with Class Form1 in the same way that multi-MODULE code interoperates.
How does one spread CLASS code across several files and still allow it to interoperate as if it were in a single file? Alternatively, how does one create several CLASS files that operate the way multiple MODULE files operate.I am sure that there are all kinds of best practices that I am violating but the goal to to get some prototype software working and interfaced to some lab equipment.

I am trying to manipulate files as part of a Document Management application that stores documents in a location on a Network Drives. But the My.Computer.FileSystem.Drives collection does not contain the Network Drives mapped on my machine. I have about half-a-dozen of these, but none of them seem to show up in the Drives collection and thus are not visible to the other FileSystem functionality I need to use for file management.
how to make sure the Drives collection contains all my drives? I am running VS2010 Premium edition on Windows 7 64-bit on a 64-bit Dell machine.

Now as you can see it is sending the textbox1 text and then pressing enter then sending textbox2 text! Theres quite a few problems in that but before i discuss note: This code is in a Timer. Problem #1: It does not send the keys fully correct all the time because its trying to send them all at once! So i want it to send them 1 letter after the other with 200 ms sleep in them! Problem #2: The sleep is not working: The reason i know is because even after it did the first textbox1 text it didnt wait that 2000 ms!

I have a filter that is used to populate a grid view and the url will conain: /example/grid?value1=1&value2=2
It will then have a link to page 2, which allows them to edit something.I then want them to click a link that will send them back to the gridview under the same parameters of: /example/grid?value1=1&value2=2
Is this possible? How do I hold on and fill in the URL values so it knows how to refill the grid view accordingly?

im making an application in vb.net (duh!) anyway i have created and coded the whole project and it performs exactly as i want it to (i dont need code help). my problem lies with the fact that my project is 2-3 parts
1.a setup form that gathers inital data about the enviroment stores this data encrypted in a config file. after inital setup this form is not displayed again. but needs to be run on both computers
2. the second form is the real application form im in the process of turning this part in to a background service anyway this form is the one that establishes the connection between two nodes it works correctly
3. the config files
anyway here is my problem i want to make this application distributional with just one file the (.exe) and have this .exe make everything else happen. it runs the setup form and creates the first config file which it does then it needs to produce a copy of just the second form and the config file to transfer to workstation #2 that will run independtly without the whole application which i cant make happen then it needs to turn both workstations application on by only starting one on either computer and invoke the other computer to start its corrosponding app also no idea how to make this happen any ideas or suggestions as to where to look to try to find my answers.im thinking i might need to make two seperate applications (a setup app, and the running app) and include them both in a project and use the setup.exe to to package them together this is a little side project that im making for my self to use to make programming a little easier so i plan on giving it out to some fellow students to test and tell me what they think so im not really worried about ease of use or complicated procedures yet but if it turns out to work and actually be of use to anyone else i would be willing to rewrite it to distribute to the masses but for now i just want it to work for me.

I'm currently developing a new system and I need to be able to upload a file from my computer to another (the server). I'm using TCP right now but I might use UDP in the future. The server I've made has multi threading so it can receive files from me while also serving another user with for example account information.[code]...

So ive looked everywhere but every example i find doesnt work on visual studio 05 and doesnt convert properly. I simply want to send info from one computer to another through direct connection. if anyone could point me in the right direction it would really be helpful. most stuff i find seems to be more complicated than what im looking for.
then just one other question. both computers will be going through a router. as long as i have the port im using forwarded on the hosts side, that shouldnt be a problem, right?

I am trying to make an app which can send/receive files/pictures. I am trying to make a app which will get a picture of the users screen and send it to me, and display it in a picturebox at a set interval. With this, I will be able to sort of see what someone is looking at without having to have him send screenshots constantly.
Remote assistance does not seem to work for these apps, shows black, but I can make the program already get an accurate screenshot and display it of this program, I just need to know how to make it send it to me and display it to picturebox.
The thing I have been using is the MultiUser TCP chat application off MSDN's website, I don't know if this will work, but I need to make it send somehow and display it.

What's the best way to do this without using FTP?
The client would need to be able to communicate with the server for several simple tasks, such as checking if the file on the client is different from the file on the server. Or issue a "create folder" command. And of course the file transfer itself.[code]...

What code can I use to send a simple text file to someone else's computer and choosing a save location and vice versa from theirs and loading it into a rich text box in their application that they have open, and vice versa? Their application is the same as mine (sort of like how an instant messenger works-except it does not save, send, and load text files like I am aiming for)

Can I send multiple files as 1 fax? I currently can fax one file at a time. I was wonder can I send multiple files to the same fax number on one call? Without physicall trying to combine files. For example. If I wanted to send a word doc and a pdf to the same person can I do that without having to dial twice? I hope that makes sense. I don't know if you can because I see that FaxDocment.body is string and not a list of strings. I am using FaxServer and FaxDocument. I just Found FaxDocument.Bodies. Does anyone have an example on how to use this? I know that FaxDocument.Body is a file path. FaxDocument.Bodies is an object? I don't see an list of path or whatever.
