//vc++:
FormatMyDisk(char * TransData, char* VolumeName)
{
char *FormatW2K = "CMD.EXE";
char FormatW2KParam[100] = {0};
sprintf(FormatW2KParam, "/C \"format.com %c:/q/x/FS:FAT/V:%s\"",*TransData,VolumeName);
ShellExecute(NULL,"open", FormatW2K, FormatW2KParam, NULL, SW_SHOW);
}
what does the identical C# code look like?

Take a look at the Process and ProcessStartInfo classes which provide everything needed to replace the ShellExecute.
The rest is some simple string concatenation you should be able to do yourself.

Print a String From Server Side C#

My question is that I have to print a string from server side C#

if(e.CommandName =="Print")
{
string parsedreceipt = null;
parsedreceipt = DecodeReceipt (e.Item.Cells[3].Text);
===> here I need to print to the printer and pass the string
parsedreceipt which is the information that I want to print.

}

I need your help badly on this one.

Here is my function:

public void ReceiptsDataGrid_ItemCommand(object source,
System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
ListItemType oType =
((ListItemType)e.Item.ItemType);
if(oType == ListItemType.Item || oType ==
ListItemType.AlternatingItem)
{
e.Item.Attributes.Add("onmouseover",
"this.style.backgroundColor='lightblue'");
e.Item.Attributes.Add("onmouseout",
"this.style.backgroundColor='Beige'");
}

if(e.CommandName =="View")
{
string parsedreceipt = null;
parsedreceipt = DecodeReceipt
(e.Item.Cells[3].Text);
StringBuilder strAlert = new
StringBuilder();
strAlert.Append("<script
language=javascript> alert('");
strAlert.Append("Receipt:" + parsedreceipt +
"\\n");
strAlert.Append("');");

this.RegisterStartupScript("startup",strAlert.ToString());
}

if(e.CommandName =="Print")
{
string parsedreceipt = null;
parsedreceipt = DecodeReceipt
(e.Item.Cells[3].Text);

}

}

Any help would be appreciated.

Reflection help - child classes

I have a base class, that defines an Enum.
I have one or more sub classes that redefine that Enum (using the new keyword).

I am trying to write code in the base class to iterate through the enum, as defined by the subclass that is calling the code.

Any ideas how? I'm trying to work my way through Reflection, and I can get all of the properties and methods, but cant get any info about any Enums that might be there.

Thanks

In case anyone cares:

// Create a variable, but from the inherited class, not this base class
Type[] tNested = this.GetType().GetNestedTypes(System.Reflection.BindingFlags.NonPublic);
object rt = null;
foreach (Type t in tNested)
{
    rt = Activator.CreateInstance(t);
    break;
}

Hi everybody.

I'm trying to create a web application with C#.net or C++ like the (windows updates from Microsoft) to let the customer of our company download automatically our executables files from the web and also let the web app automatically the install those files on their computers.

If somebody has any idea of how to do it or any source code about it, I’d appreciate.

Thanks

Well Windows Update uses a service called Background Intelligence Transfer Service (BITS). You can use this to download files or updates, then you'll have to write some code to update your application. Smile | :)

Of course you dont have to use BITS, you can write your own downloader or use WebClient.DownloadData/File if you dont mind it holding up your app... Smile | :)

Hi gurus,

With WMI and C#, how can I detect if a network adaptor is a virtual or physical?

Thanks.

Best regards.

You can't check for a flag like that, but you can use the available information to POSSIBLY figure it out. Most virtual adapaters will not have an AdapterType in their Win32_NetworkAdapter class. Physical adpaters usually will. For example, you could check each adapter for an "Ethernet 802.3" Adapter Type.

Hi,

It seems that I have the correct information when I do the following SQL statement on WMI:

SELECT Description, IPAddress FROM Win32_NetworkAdapterConfiguration WHERE ((DHCPEnabled = 'TRUE') AND (IPEnabled = 'TRUE'))

But I don't know if it will work on manually configured ethernet adapters.

When I do a request on Win32_NetworkAdapter class with the AdapterTypeID set to 0 (Ethernet 802.3) I get back the 1394 adapters and a lot of other adatper types while I need only to retrieve physical network Ethernet adapters (no virtual ones).

No, it won't. Even VPN adapters can have those properties set to True. Also, not all properties of the class are set by the drivers manufacturers. AdapterTypeID, since it is available in XP and above only, might not be set. It, also, does not support a NULL value, so if it is not set properly, or at all, it defaults to 0. Use the string parameter AdapterType instead.

Thanks.

Hi - not a guru here but what I use to populate a combobox is: combobox.Items.Add([value]);
Not sure what you need to use to replace GetItemData I use an equivilency test eg: if([value].Equals(combobox.Text))...ect but there maybe a better way.

Hope this helped Wink | ;)

I don't know if it is what you found out, but you can add any object to a ComboBox, and it's the result of calling that object's ToString() what gets displayed in the ComboBox.

So, just create a little class that contains all your data in public fields (or properties or whatever) and override the ToString()member. Add objects of that class to the ComboBox, and that's it.

Hello everybody. I'm writing from Seville, Spain. I'm trying to build a Test-generator application through a shared add-in hosted in Word, and I need to transform .xml documents to other formats like .doc, .html and .rtf. I'm convinced that possibly there are libraries, components or classes that allow these transformations.
Does anybody know something about this respect??
Has anybody ever been in a similar situation??

Thank u very much

You'll have to cast the return value.

public static System.UInt16 MAKEWORD(byte a, byte b) 
{ 
	return (ushort)((ushort)a | ((ushort)b << 8)); 
}

WebClient DLoad = new WebClient();
DLoad.DownloadFile(path, "MyFile.xml");

that works fine...!

But then when i want to uploade the file..
I have no idea how to do however i tried this...

WebClient ULoad = new WebClient();
string path = @"http://www.whatever.com/web/MyFile(1).xml";
ULoad.UploadFile(path, "MyFile.xml");

But it throws an "'System.Net.WebException' occurred in system.dll -
Additional information: The remote server returned an error: (405) Method Not Allowed."

I have no idea what to do now....
Need a way to upload the file to the server.... or to write to the xml that already is on the sever...!

Can anyone help me please...?

bound control looses changes after leaving panel

Peter Kiesel31-Oct-04 3:25

Hi All,
I have bound textboxes and other controls on a panel. If I edit the text in a textbox and move on to another control, everything works fine and I can use
HasVersion(DataRowVersion.Proposed)
to determine if there have been any changes to any control.
BUT, if I make only a single change to one text control and leave the panel afterwards by clicking into another panel on the screen, the proposed version flag is not set and I'm missing to save the change to the underlying dataset and database.

Binding:
txtCode.DataBindings.Add("Text", m_vProject, "code");
...
and after leaving the panel:
BindingManagerBase bm = BindingContext[m_vProject];
cPrjDs.tProjectRow prjRow = (cPrjDs.tProjectRow)(((DataRowView)bm.Current).Row);
if (prjRow.HasVersion(DataRowVersion.Proposed)) {
if (MessageBox.Show("save changes?", "header", ...)) {
bm.EndCurrentEdit();

To my understanding, it would be possible to catch the TextChanged event of the control and start DataRow.BeginEdit(), but this does not seem to be a practical solution for lots of controls.

Thanks for any help.
