Hi,
The only thing that matters is that through sockets you have to send a byte array. It doesn't matter what that array contains. All that is important is that you must know what you are reading and in what order.

Hi All
I am trying to make an application like MS Paint, and I don't know how to converting the drawings in my graphics object into an image and save it on the hard disk
is there anybody can help?
thx
|

|
|
Your graphics object can only be drawn to if it contains an Image or Bitmap, and the Bitmap class has a Save method to save it to disc.

is this right way to bind data with texboxes when you use classes,i mean i need to display data on labels.
private void btnGo_Click(object sender, System.EventArgs e)
{
try
{
SearchCustomers search = new SearchCustomers();
string Barcode1;
string CustomerName="" ;
string Barcode;
string ProductName="";
string Price = "";
search.CustomerName = "jakes";
if(txtBarcode.Text.Length <4)
{
Barcode1 =txtBarcode.Text;
lblCustomerName.Text = CustomerName;
search.SeachCustomer( CustomerName, Barcode1);
}
else
{
Barcode = txtBarcode.Text;
lblProductName.Text = ProductName;
lblPrice.Text =Price;
search.SeachProduct(Barcode, ProductName, Price);

Hello,
This is what I'm trying to do.
Get the public folders out of each Exchange Server (that is visible through the Exchange System Manager). As the select * from exchange_PublicFolder only shows the folders at the highest level and not per storage group I looking at the ADSI approach.
this is the code so far. Parts have been commented out as I'm testing this new part with ADSI.
<br />
try<br />

msExchPrivateMDB is the name to select the mailbox data. I'm sure there must be one for public folders as well ?
Any help would be greatly appreciated.

when I am pressing backspace I want some variable value should change(i=3).So how to do it

Hi,
You can write the code in KeyPress event. You get e.KeyChar. Check if it is Backspace and if yes execute some code. as simple as that !

Hi,
In my application i need to know when the monitor has changed state from stby to normal.
I know how to put it to stby using SendMessage, but what i need to know is when it wakes up (when the user uses the mouse or keyboard, for eg..).
Any help is appreciated.

I have unmanged DLL (legacy - can't touch it!) which returns an XML string. I want to bind this string to a datagrid....easy...or it should be. But I can't. I've isolated the problem below. To get the xml string into a dataset, I use a StringReader and use ReadXml. But when binding to Datagrid, it only shows the root node if I haven't pre bound the columns, or if I have, it complains the field isn't there (as it only exists in teh child nodes). I have saved the output from the Unmanaged DLL to an XML file which can be parsed, so the format is correct.
To test, I use two methods of populating the grid. The first one works fine, loading the XML file into an XMLDataSource. The second one doesn't - loading the XML file into a DataSource, via ReadXML. It is this second optoin I need to work, or some method of doing this where i can pass an XML string in.
works a treat, but I can't use as I have to receive from a string, not a file
XmlDataSource xds = new XmlDataSource();
xds.DataFile = ("d:/test.xml");
GridView1.DataSource = xds;
GridView1.DataBind();
doesn't work as it only seems to look at root node.
DataSet ds = new DataSet();
System.IO.StreamReader str = new StreamReader("d:/test.xml") ;
StringReader rdr = new StringReader(str.ReadToEnd());
ds.ReadXml(rdr);
GridView1.DataSource = ds;
GridView1.DataBind();
Any ideas?
Regards
Malc

err
maybe you should use ReadXmlSchema().
|
|
|
|
|
The Dataset, read from an XML string contains multiple tables. The first table (the default) is the root node, the second table, contains the child nodes...so...changing the following line works a treat..
GridView1.DataSource = ds.Tables[1];

Can anyone tell me howa user can connect to the internt using my software. I want the user to be able to feed in the username and password and when Connect is clicked - the application connects using a network conmection on the computer. I would also be able to check wether authentication was successful and the connection state. Whioh library do i have to use. I tried googling it up but i couldnt find anything specific. I believe it is called "RAS" - am i correct? Thanks all.

Why use a 3rd library. You got all you need in System.Net namespace and namespaces derived from it like System.Net.NetworkInformation

Dear gurus,
I have a generics question.
// T is either Int32 or Double
void fkt<T>( ref T someValue ) where T : IConvertible
{
Int32 i = 5;
someValue = i; <---- compiler error here
someValue = (T)i; <---- compiler error here
}
In both cases I get a type conversion error
How can I handle this? I know in advance, that T is only Int32 or Double.
Thanks for your help

Hallo,
does not work. Still same compiler-error-message
Kind regards

void fkt<t>(ref T someValue) where T : IConvertible
{
IConvertible i = 5;
someValue = (T)i;
}
Generics kind of suck. They aren't a pimple on the backside of C++ templates.

Wow ! ! !
Thank you ! ! !
You seem to be an absolute expert.
But two new questions arise: -))
1.
From where can I get such know-how? Is there any good book/paper available on such details?
2.
How can I restrict my Generic Type <t> to the basic datatypes as e.g.: char, int, double,..
fct<t>( T value ) where T: ...basic numeric types only ...
Kind regards

*blush* I googled it. I've only really used generics for typed containers, I was interested enough to know more that I was willing to spend a little time researching it and playing with a sample app.

It looks to me like it's not possible.

I believe it is. This method should only work with int and double types only
private void CreateMethod<T>() where T : IComparable<int> , IComparable<double>, new()
{
T instance = new T();
MessageBox.Show(instance.ToString());
}
