I have an app which communicates with a SharePoint server, and one of the things it does is uploads files to the SharePoint server using a HttpWebRequest.
However I have found that this doesn't work when the file being uploaded is bigger than about 2mb and either of the following conditions apply
- The user is at home and is using VPN to connect to the newtwork
- The server is hosted on an ordinary broadband connection
The request throws an exception saying 401, unauthorized.
Using Fiddler to examine the http request going back and forth, I found that the exception is somewhat incorrect, and is actually referring to the first request of a pair (the first doesn't supply username/password, server asks for authorization, the second supplies the username/password). What has actually happened is that the server has just closed the connection and no reason is supplied as far as I can tell. It *might* even be a gateway timeout, but I very rarely even get a reply from the server under these conditions
Using a Win32 app I have for testing things like this, I found that WinINet has no problems putting the file onto the server.
I'm a little baffled as to what is happening here. Has anyone else had something like this or have any solutions?

Hello.
I have encountered a strange issue. I have a form consisting of some tabpages within a tabcontrol. On the tabs, different user controls contain text boxes and combo boxes that are data bound. My problem is that navigating between the controls with the Tab key doesn't work.
Combo boxes: When the type is set to "DropDownList", the Tab key is ignored, but when the type is set to "DropDown", it works like supposed.
Text boxes: Treat Tab key like an input and tabs the text in the control.
I have only my own controls, derived from the windows classes (e.g. ComboBox and TextBox), the property TabStop is set to True, and they have Tabindices positive, non-zero values.
What could be wrong? Especially the difference in behaviour between the two types of combo boxes really confuses me.
Thank you

hi friends,
can i control the text to be typed in a textbox?
i.e. i want only hex data (A-F, 0-9)to be typed by the user, he should not be able to type any another data. i tried to use the keydown property
also, can i delete a perticular charater from the textbox?
i want the user to enter the MAC address in the form 3A:26:b9:12:34 in the text box. but when i process the text in the textbox, i want to exclude the ':'. how can i do it?

1. There should be an event when the textbox-contents changes.
-> get the string out of the textbox, check for illegal characters, delete them, put text back into the textbox.
2. Like 1., you can get and set the text from the textbox with the "Text" property.
look on msdn for more info on the textbox members and properties.
good luck.
No hurries, no worries.

1) Use the KeyPress event, if the character is invalid set the e.Handled property to false, and then it won't appear in the textbox.
2) Use macAddr = textbox1.Text.ToString().Replace(":", "")
Note this is from the top of my head and the syntax may be slightly off
Hope this helps

Hello,
When I create a application in C#, a "public void" Main appears. This is the applications entry point. In fact, this sub has nothing to do with the class containing it. For example, it seems like this:
{
Application.Run(new Form1);
}
But when this Form1 has to load another form, for example to enter your name, and that second form has to store your name in a variable in the main form, how do you have to point to the form with wich the application started?
I've tried the following changement in the 'Main' sub:
{
Form1 f1 = new Form1();
Application.Run(f1);
}
I thought that I could point to the startup instance from Form1 by using 'f1' but this doesn't work. I've also tried it by setting an empty class only containing the "void Main" as startup object, but this also has no result. From the point where you use Application.Run... the instance isn't available anymore.

The reason that doesn't work is that your variable f1 is only valid within the scope of the Main() method (not "sub")
I suggest that when you write the code that does the SecondForm.Show() you should pass a reference to this to the SecondForm. You will have to create a property in the SecondForm to accept the main form as a reference. Store this reference in a member variable.
For example:
SecondForm sf = new SecondForm();
sf.MyMainForm = this;
sf.Show()
Then when you have the variable that needs to be sent to the main form you can do something like this:
MyMainForm.Name = this.nameTextBox.Text; This will require a property on the main form to be set up to receive the variable.
Does this help?

1. You can add extra files to the Windows Installer file using a Deployment Project. I don't know if it's possible to copy files from another location or run other installers from a Deployment Project. (You can always write your own "installer" using C#, as long as you make sure that .NET Framework is installed prior to running it).
3. There are some third party products available, for example Wise and InstallShield. There are also some free install systems, for example NSIS, but they don't use Windows Installer.

You can use the GetElementsByTagName method of an XmlDocument object. The method will return an XmlNodeList that is enumerable. The following code assumes that you have an XmlDocument set up in the variable xdMyXmlDoc.
XmlNodeList xnlElements = xdMyXmlDoc.GetElementsByTagName("WORKSPACE");
foreach(XmlElement xeThis in xnlElements)
{
// Do something
}
If you don't want to fetch XmlElements, change XmlElement within the foreach to whatever is in your Xml file.

Thank you

Storing binary data in a databaser is usually done using some form of BLOB field, SQLServer has the Image datatype which would work... can I ask why you dont want to do this?
VictorVB wrote:

I assume you've used Base64 encoding to turn the binary data to a string, again this will work but I dont think there is a way to reduce the length of the data.
The only advice I can give you is to store the path to the file in your database (No BLOB Field and no long string data), but thats not what you said you wanted to do.
