I don't see the distinction you're trying to make.

This doesn't change the code generated by the compiler at all. What you're actually doing is changing a configuration option in the applications .config file that say that this application CAN run under the 1.0 Framework.
There is nothing guaranteeing that though. The .NET Runtime is trusting YOU to tell it that it is OK to run this particular 1.1 code under the 1.0 Framework. It's taking YOUR WORD that the code doesn't use anything that is 1.1 specific.

c# is closer to VB than to VC++ as far as developing a GUI. With your experience in VC++, the programming side should pose little problems - just get a good reference book and you'll be fine. If you have VB experience the whole transition should be a piece of cake for you.

Hi..
I have connected to a Unix based data base server by using the tcpclient class of c#, for a synchronous transmition of data i am using the receive function provided by the above mentioned class. as it is said in its help that "receive() function stops untill it receives that data from the host"
My problem is when i send a query to the host, Reply does come from the host but the function "Recevie()" does not stop for the new data to come from the host or does not wait for the new data all it does is keep on giving the same old data that it sent before ,due to this my client is not working fine... if some one has information regarding this do help me.

Hi,
I am having a problem when trying to update a table in Access 2000.
At (apparently) random times, it throws the following exception. It is translated from spanish, might not be exactly the same in english;
'Can't update. This record is currently locked'
There is no concurrent access to this database. Any ideas?
Thanks in advance

The first thing I'd ask is, "Did you close all of your object when you where done with them? DataSet's, DataReader's, Connection's, ..." Don't keep a connection constantly open to a database. Keep it open only as long as you need to complete the transaction you need.

Well I have a couple datatables pointing to the database through the same connection, but NEVER had problems until now.
Thought the locking policy came into play when there was more than one user accessing the database. Still, I'll give a look and try to keep 'data objects' to a minimum.
Thanks for the reply

And can i move an object at a bearing of, say, 65 degrees?
I've done something like this before, but it runs really slow, and i cant move in certain angles.
|
|
|
|
|
What kind of object?
Moving an object is simply changing it's position. If the object supports changing of the position, it can be moved.

You have an executable named shutdown.exe in windows, you can run it to restart the computer.
The command line is: shutdown -t 0 -r -f
I know the Windows 2003 and Windows XP provide this executable.
Good luck,

Hi, I am creating my own datagrid control, as I needed the vertical scrollbar to be thicker than standard (because this dg is targeting touch screen users). Anyway, I am overriding WndProc, seen in the code below:
protected override void WndProc(ref Message m)
{
try
{
if (m.LParam == this.VertScrollBar.Handle)
{
object result = m.GetLParam();
}
}
catch (Exception ex)
{
string test = ex.ToString();
}
base.WndProc (ref m);
}
My problem is that GetLParam takes a System.Type cls parameter, and I have no idea what I should be putting in there. Please let me know how to fix this if you know what should go there. Thanks in advance.

Hi!!
I am a bit confused with regards to constant variables. I have a class called something like MYGlobals (for example). In this class I want to define global variables used throughout my web project. I think there is 2 ways of doing this, or am I mistaken. For example, are the following 2 declarations basically the same thing?
public static const int C1 = 5;
public static readonly int C1 = 5;
What is the correct way to define constants?
Please help and advise!!
I appreciate your help.
Regards,
Brendan

A constant can not be static.
public const int C1 = 5;
Be ware that the value is compiled into the code wherever you use the constant. If you change the constant you have to make sure that all code using it is recompiled. This is not a problem within a single project of course.
public static readonly int C1 = 5;
When the class is loaded the integer is created and initialized. (The initialization is done in the static constructor of the class.) The value is not compiled into the code, but referenced whenever it's used.

Can anyone explain me about the differences between HashTable and ArrayList
|
|
|
|
|
In an ArrayList you get a dynamic list of object that are accessable by their index in the list.
A HashTable allows you to store an arbitrary key for each object. If you use an integer you increment after each add to the HashTable, then you'll get approximately what an ArrayList can do, but usually the keys are chosen differently and more appropriate to the way you want to access the HashTable entries.
For example, you could add objects to your HashTable with an object ID as key.
That way you can easily get the object for a given ID without having to run through the ArrayList and search for the object with the matching ID.
Regards,
mav

Hello,
This week I was given something cool to do. Take a Tablet and Ink enable our Tiff viewing app. Sounded easy. This is what I have:
1 Microsoft.Ink.InkPicture inkPic, that I’m loading with inkPic.image = SomeTiffFromFile
I’m not bothered by scaling problems yet.
This control captures Ink and saves it as Strokes and it works wonderfully. I’m trying to save the Ink into the Tiff.
This is what I have tried:
First I bring the Tiff into Drawing.Bitmap bmp = Image.FromFile(“filename”) (this is the same file I use as the inkPic.Image) Then I make a new Graphic from the Bitmap. Since Ink is made of Points (Ink.Strokes[Foreach].GetPoints(Foreach)) I figured I could do this
Graphics g = Graphics.FromImage(bmp);
for (int i=0; i{
p = this.inkPicture1.Ink.Strokes[i].GetPoints();
foreach (Point x in p)
{
g.DrawLine(pen, x, x);
}
}
bmp.Save(nameBase+".tif", System.Drawing.Imaging.ImageFormat.Tiff);
But that isn’t working.
I took the tmplate for this project from the PaperForm that came with the Tablet SDK. However it doesn’t save any thing and all the SDK examples that save save the Ink speratly from any image using Ink.ExtendedProperties.Add(guidImage, Gif);
I need the Ink burnt into the Tiff as one document.
Out prototype used a brush instead of Ink and it didn’t seem to work well. Too choppy. The InkPicture feels a lot nicer to use.
Ps. Does any one know a good comprehensive book about handling Tiff with GDI+
Thank you for any feedback
