You can use ToolStripSeparator class.

As advertised! That was what I was looking for. Thanks!

When I added the MenuStrip, I noticed that the menu is now in the client area were as Menu move the client area below the menu. Is there an easy way to fix this or is there a way to measure the MenuStrip height?

Hello everyone,
I am currently using this line of code to create a child form and pass the value in the constructor.
// Get the value to be passed
string parentValue = this.DataBaseName;
// Create the child form and pass the value in the constructor
this.childC = new ChildCForm(parentValue);
Could you tell me how I can pass more than one value?
Thank you very much for your help.

just add as much as you want parameters to the constructor.....
like this........
public Class1(int intID, string strName,.........)
{
}
When you get mad...THINK twice that the only advice

Hello khoramdin
if you want to pass more than one value in constructor you can define more than one constructor for childForm accorrding to your passed values.
such as :
public class childForm
{
public childForm(string val1)
{
}
public childForm(string val1 ,string val2)
{
}
public childForm(string val1,string val1 ,string val2)
{
}
}
and then when you create instance from childForm you must invoke the proper constructor to your values which will send from parent to child.such as:
// Get the value to be passed
string parentValue1 = this.DataBaseName1;
string parentValue2 = this.DataBaseName2;
string parentValue3 = this.DataBaseName3;
// Create the child form and pass the value in the constructor
this.childC = new ChildCForm(parentValue1,parentValue2 ,parentValue3 );
I think that's all.

Hi,
I have textbox that is bound to a field in a bindingsource. The value entered into that textbox is also the same as another field in the same bindingsource. Specifically they are the initial amount of an invoice and the amount outstanding for that invoice.
The user obviously only needs to complete the one textbox but I want the same amount entered into both fields.
How can I "bind" the two fields to the same value without a lot of processing/code?

Any faster method to change the contrast of ab image......... OTHER than that unlock and unsafe method its very slow...... Is there anything else?????????
|
|

You can adjust brightness and contrast through a matrix operation in GDI+.
// return matrix for the specified contrast
public static float[][] GetContrastMatrix( int percent )
{
// perform contrast by setting the scale and offset at the same time
// calculate the scale and offset
float v = 0;
if ( percent > 0 )
{
// range from 0.0 (no change) to 3.8 (high contrast)
v = 0.0195F * percent;
v *= v;
}
else
{
// negative value, -1.0 is gray and 0.0 is no change
v = 0.009F * percent;
}
float scale = 1 + v;
float offset = v / 2;
// setup the matrix
float[][] matrix =
{
new float[]
{ scale, 0, 0, 0, 0 }, new float[]
{ 0, scale, 0, 0, 0 }, new float[]
{ 0, 0, scale, 0, 0 }, new float[]
{ 0, 0, 0, 1, 0 }, new float[]
{ -offset, -offset, -offset, 0, 1 } };
return matrix;
}
That returns a contrast matrix. This code:
ColorMatrix cm = new ColorMatrix( matrix );
ImageAttributes attr = new ImageAttributes();
attr.SetColorMatrix( cm );
Creates an ImageAttributes object that uses the matrix. Then the Graphics class has a DrawImage overload ( or more ) that take this ImageAttributes class as a parameter.
I should write an article on this, to complement my articles showing the 'lock bits' way of doing things.

I've the following Problem. I need to populate a TreeView from a Database.
The Table looks like this:
Typename|rule.id|Rule_Prio|Level|Typename
"Vehicle","Vehicle=Car+Pickup",1,2,"car"
"Vehicle","Vehicle=Car+Pickup",1,2,"Pickup"
"car","car=carWithoutTrailer",2,1,"carWithoutTrailer"
"Truck","Truck=HeavyTruck+LightTruck",1,1,"HeavyTruck"
"Vehicle","Vehicle=Truck",2,2,"Truck"
"Truck","Truck=HeavyTruck+LightTruck",1,1,"LightTruck"
"car","car=carWithTrailer",1,1,"carWithTrailer"
"Pickup","Pickup=PickupWithoutTrailer",1,1,"PickupWithoutTrailer"
The Vehicle is the rootNode. It's no problem to get it from the Database. One of my biggest problems is: no Primary key exists for it. So it's hard for me to find a recursive solution. I think a Picture says more than words.
It should look like this:
Picture of how the Tree should look like
The Rule_Prio is always a node after nodes to group them.
Ive already created a connection to the Database. Created a DataAdapter and filled it with a DataSet which contains the Table.
Every try to build this tree leads to a stackoverflow or leads to different problems.
I read all the TreeView Tutorials in here but there recursive solutions didn't help me much because they often work on a primary key or better an id which is an int and which is autoincremented.
Any ideas?

FYI - your link does not work.
I'm not clear on Rule_Prio or Level but here's one thought:
Make sure the list is sorted such that the parent nodes come before child nodes. e.g. in your list "HeavyTruck" is listed before "Truck" has been added to "Vehicle".
Use Typename to find the parent node.
Add current item as child to parent node.
It is relatively slow since you must find the parent for each addition.
Good Luck.

Ok thx.
I corrected the link. But i'm not able to get the priority into this.
|
|
|
|

Not sure I understand you. Are you having difficulty adding the priority node to its parent node? Why?

How do i get the byte[] associated to the System.Drawing.Bitmap class???
a fast and helpful answer is requier 
KainPlan.
|
|
|
|
|

Yeah i know this... it works... but the display works with 8 bit per pixel and the result of viewing the bitmap is not what it meant for. (sry for bad english) I need to Convert the Bitmap or the array but it all happens in a rendering thread at 10fps and a convert like this:
for (int y = 0; y < bmp.Height; y++)
{
for (int x = 0; x < bmp.Width; x++)
{
byte b = 0;
if (bmp.GetPixel(x, y).B < 128)
b = 128;
arr_bytes[i] = b;
i++;
}
}
is too slow.
Edit:
(if b >= 128 the display draws a black pixel.)

Use System.Drawing.Bitmap.LockDIBits() and System.Runtime.InteropServices.Marshal.Copy
