I tried what you suggested, that did not work. The program was not responding. Thank you for suggesting. I will continue to dig deeper.

I'm not surprised it's not working. As a small point, could you please post code that stands a chance of compiling. There isn't a HttpWebRequest.Create - it's WebRequest.Create.

Your problem here is that you are just reading the data into a stream, which you then dispose of. What do you think the stream at the server end is going to do? You actually need something there to take that stream and write it out to a file. That's the part you're missing here.

I was brought up to respect my elders. I don't respect many people nowadays.

Actually, using HttpWebRequest.Create I was able to download a file from remote server to a specified location.

Now, I want to be able to upload a file to a remote server using

HttpWebRequest.Create(

.

The code works using WebClient class, to upload and download files, but there is not much error trapping that could be coded for. On research the better option was to use

HttpWebRequest

.

Hello Guys,

Hope you are doing good.

I am developing a Designing Application. In this application there is a feature where user can add multiple images on form(can drag here and there).

I have few GIF Images of Cartoons. I want to show them as GIF Only. But when I put image on form it shows White area in blank portion.
Confused | :confused:

I have used Panel and Images are set as Background Image in the Panel.

I think I have not described clearly. Here I have attached image link for more clarification.

In this image background is a Panel(pnlMain) with a Background image. And Spider man is in another panel (panel1) with Background Image in panel1. Spider man image is GIF Image with Transparent area around spider man.

Image is here in this link.http://www.evernote.com/shard/s263/sh/8afc9a41-2a22-4a46-9703-33b77bb93f11/c1ecd6fb6a2ec44f6ac324e6482c4e6e[^]

I appreciate your cooperation.

Install software and menus depending upon radion button selection option used in MSI

Hi,

I made simple winform application in C#. I am showing menu options depending upon the mode selection. .i.e. if mode is eng then I am showing all the menus in MDI and if mode is tech then I am hiding some menus of MDI.This is handled in Code.

I am using MSI to create setup.I am using custom dialog box i.e. 2 radio button for mode selection. Now I want install software depeding upon the mode selection. i.e. if I select Eng mode radio button then installer install software with all menus and if I select tech mode then installer install only few menus which is applicable to tech mode.

I dont know how to use custom action so that i can pass the selection option to the exe.
Is there any other solution just let me know.

Thanks,
sjs4u

So the "mode" (eng/tech) is passed as a command-line parameter? I think you could add that part in the shortcut that's being made.

Alternatively, you could write a setting during the custom action[^] and check it's value on startup.

Hi Eddy,

Thanks for your reply.

Yes I am passing tech/eng mode values as commadline argument and checked that in Main Method in program.cs. Default is tech mode.

In Installer Project - I set the radio button values and can able to get these values using
string myInput1 = this.Context.Parameters["BUTTON1"];
string myInput2 = this.Context.Parameters["BUTTON2"];
Now when I start installer it is showing 2 radio button and in that i want selected radion button value to be passed to exe so that only that exe get installed.

sjs4u

Most installers will allow you to create a "default" and a "custom" setup; simply install a different shortcut on the desktop, and put the argument in there.

"How" that's done will vary per installer; check it's manual.

What's actually in the byte array?

You're swallowed exceptions in serialisation which is a really bad idea as it makes it impossible to tell if that failed.

The problem is that one of the keys you attempt to read doesn't match the name of the key that you write. It's generally a bad idea to use strings like this in serialisation code - you should really use constants. That way, you make sure that the string is the same on the input and the output.

This code has the problem:

[Serializable()]
       public class index   //object idex indicate where cube entry on the screen from other player
       {
           public int x;
           public int y;
           public int indexOfTargetCube;     // that mark own of index( cube)
           public byte direct;
           public index()
           {
           }

             public index (SerializationInfo info, StreamingContext ctxt)
          {

              x = (int)info.GetValue("x", typeof(int));
              y = (int)info.GetValue("y", typeof(int));
              indexOfTargetCube = (int)info.GetValue("temp", typeof(int));
              direct=(byte)info.GetValue("isConnected",typeof(byte));


          }
             public void GetObjectData(SerializationInfo info, StreamingContext ctxt)
           {
               info.AddValue("x", x);
               info.AddValue("y", y);
               info.AddValue("indexOfTargetCube", indexOfTargetCube);
               info.AddValue("direct", direct);
           }

       }

You use indexOfTargetCube when you write the data out, and you use temp when you read the same item back in.

Tab control? If you are using Pivot view, you can set a background image as described here[^].
