Hola, I am trying to use C# to make a HTTP POST request. This request should carry file data, and have some parameters in it as well.
This is quite easy with HTTPRequest, but the problem is, I need progress information as well, and the only apparent way to do this is to use the WebClient classes (UploadFile or UploadData). I've been trying both the whole day, without much success.
My code looks something like this:
WebClient client = new WebClient();
Uri uri = new Uri(url);
// Placing the parameters in a name-value collection
NameValueCollection param = new NameValueCollection();
foreach(string[] nameValuePair in parameters)
param.Add(nameValuePair[0], nameValuePair[1]);
// Addin headers.
client.Headers.Add("User-Agent", "MyApp");
// Adding the parameters
client.QueryString = param;
client.UploadFileAsync(uri, "POST", fileName);
Basically, judging from the server response, it appears that the server can see that a file is coming in, but cannot read any of the parameters that I send along in the request. To make matters worse, WebClient is doing something dodgy while using the HTTP protocol: none of the requests turn up on my HTTP sniffer! So I can't tell what is going out of my computer.
Help!!!

Check for differences in video card/processor and drivers.
We need to graduate from the ridiculous notion that greed is some kind of elixir for capitalism - it's the downfall of capitalism. Self-interest, maybe, but self-interest run amok does not serve anyone. The core value of conscious capitalism is enlightened self-interest.

The problem was that one machine had large font set and the other small font, and a status bar displaying hints was changing size by one pixel when large font was set. Thanks.

Is there a way to detect the plugging and un-plugging of a device on a Serial Port?
The requirement is such that during application runtime, if a device is connected to the serial port, the application should be able to detect the device.
Help needed PLEASE.

Normally if a device is ready to operate, it asserts the DSR (Data Set Ready) line. You can check for this in code using the GetCommModemStatus API (for Win32). Polling is generally considered a bad idea - you can wait for a change in these flags to occur with the WaitCommEvent API.
From .NET Framework 2.0, these map to the DsrHolding property and PinChanged event of the SerialPort class.

Hi,
I was hoping if someone could help me with this problem. I want to edit
datagrid entries without using a linkbutton column for edit and update.
maybe we could do this using javascript. But I dont know how?
On an 'edit settings' button click outside the datagrid, the cells in the datagrid should change into dropdownlists and textboxes with earlier values maintained.
Thanks!

Hi, i'm trying to get a service to create a process text file on a 2nd machine (xp) from a w2003k server. however it fails in a grand way when it tries to create a streamwriter on the xp box! i understand it may be to do with the account etc, but i've set the log on tab for the serviec to be admin but it still fails, i've tried 'p:\thisfolder' as well as '\\thismachine\thisfolder'.
Can anyone point me in the right direction as it's been days of hell on this one.
Thanks

Mapped drives are stored in the user's profile, and services don't load the user's profile, instead using the default user profile. I'd use a UNC path. We found when doing scheduled backups remotely using NTBackup, scheduled with the Scheduled Tasks feature, for a mapped drive to work successfully, the user needed to be logged in. Switching to a UNC path meant that the user no longer needed to be logged in.
Network shares should be accessible by a service as long as either a) you use a domain account which has permission to write to the folder or b) the user account name and password on the client match with the same account name's password on the server.
You should check the NTFS permissions on the share as well as the share's permissions. Both need to allow the write for it to work. I normally just leave share permissions at Everyone/Full Control and rely on the NTFS permissions.

Cheers, i managed to get it sorted, i thought i'd had the right permissions set but seemingly didn't.

Hi everyone,
I have to convert video files on the fly and I should export some video frame as a jpg (and get video props - duration, etc...). This should be done in an asp.net page.
I've seen ffmpeg does the first work in an excellent way, but I have to execute the external exe... The problem that in hosted environment it's not possible...
Do you know if ther's a project that have already ported ffmpeg to .NET? Or if there's a wrapper for interfacing with ffmpeg dll? I've searched on the net but I found nothing...
For the second task (export some jpg and get info) in php there's ffmpeg-php ... Is there an equivalent project for asp.net?
These are the solutions I've found... If someone knows a different solution I'd appreciate it very very much! 
thanks in advance...

SPend money to replace your timerware demo with a normal license.
|
|
|
|
|
one way to make it work is by unistalling it then cleaning up your registry manually.then reinstall it. however, like Dan said, you can spend money and buy the license.

Hesbon.

Hi,
I hope this is the correct newsgroup for this question.
I am creating a test web service that I wish to extend.
The example I am working from suggests that Web Services can be called direct using HTTP GET, eg:
http://server/webServiceName.asmx/functionName?parameter=parameterValue
However when I try this I get the following error:
Request format is unrecognized for URL unexpectedly ending in '/functionName'.
It works fine if I first call the service, click on the public method and then invoke.
I am using IIS5.1, VisualStudio2005 and .NET 2.0
What am I doing wrong? (I even tried altering the IIS settings without success)
Thanks in advance
Andrew

Have you tried this below?
http://server/webServiceName.asmx?parameter=parameterValue

Hi,
Yes, however this acts as though I have missed off the
?parameter=parameterValue section.
ie: It returns the usual page listing all the public methods for the web service as though I had used the basic URL: http://server/webServiceName.asmx
Any other suggestions/options?
Thanks Andrew

The subject is really too involved to go into in a forum post. The best source I know of is 'Programming Server-Side Applications for Windows' by Jeffrey Richter and Jason D. Clark (Microsoft Press), but unfortunately I believe it's out of print.
You might be able to get a copy from Amazon Marketplace[^].

Hi all
Is it possible to anti-alias the edges of a rotated image using GDI+/.Net 2.0? I am rendering an image onto another and because it's rotated it'll have jaggies. I know that you can use InterpolationModes and SmoothingModes but it doesn't seem to affect the edges of the image against the background image.
Any pointers?
Thanks
|
|
|
|
|
I don't think so. But you could adjust the alpha values of 'all pixels at the edges' prior to call DrawImage. Probably this helps a bit...

Thanks mate. I forgot about trying that. I'm using PNG images so it should work.
Cheers!

I have a DataGridView object and I added a ContextMenuStrip control to the DataGridView.ContextMenu. This works well, if I right-click the datagrid view I get the context menu I wanted. The problem is, I would like to, just before the context menu appears perform a left click to also select the cell or row under the mouse at that moment. Not sure what is the best way to do this.
Thanks.

Hi, Johnny. This CellMouseDown event handler should work:
private void dataGridView_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
if ((e.RowIndex >= 0) && (e.ColumnIndex >= 0))
{
dataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex].Selected = true;
}
}

WOW, that was so simple, thanks a million times Andrew
