Hi,
I need to delete all the radiobuttons in a panel (other controls are in panel as well). This code I came up with only seems to get ride of some, but not all  (
foreach (Control control in panel_Label.Controls)
{
if (control is RadioButton)
{
control.Dispose();
}
}
thanks,
Ron

Probably some of the radio buttons aren't direct child controls of the panel, but childs of childs (of childs ..) of the panel.?

Hi Rick,
All radio buttons are added at run time with this code (to the same panel):
RadioButton newPointer = new RadioButton();
newPointer.Size = new System.Drawing.Size(78, 16);
newPointer.CheckAlign = ContentAlignment.TopLeft;
newPointer.TextAlign = ContentAlignment.TopLeft;
newPointer.FlatStyle = FlatStyle.Flat;
newPointer.Text = pointerName;
panel_Label.Controls.Add(newPointer);
thanks,
Ron

OK, so no recursion or iteration of additional controls is needed. Try to explicitely remove the radio button from the panel before disposing it.
foreach (Control control in panel_Label.Controls)
{
if (control is RadioButton)
{
panel_Label.Controls.Remove(control);
control.Dispose();
}
}

Hi,
Thanks for your help.
I tried your code, but same thing is happening. If I change anthing else, it works fine:
foreach (Control control in panel_Label.Controls)
{
if (control is RadioButton)
{
control.Text = "New Text";
}
}

Errh, should have seen it immediately. The problem is the foreach loop that prevents you from changing the iterated collection. Change it to a for loop and it should work.

try this
call the method on pageload
RemoveRadioButtons(MyPanel);
here's the method...
public void RemoveRadioButtons(Control parentControl)<br />
{<br />
foreach(Control childControl in parentControl.Controls)<br />
{<br />
if(childControl.HasControl())<br />
{<br />
RemoveRadioButtons(childControl);<br />
}<br />
elseif(childControl is RadioButton)<br />
{<br />
parentControl.Controls.Remove(childControl);<br />
}<br />
}<br />
}

Mark

i want to tell application to chane location of button on runtime
for example
if i want to change button2.location
button2.location=""
but if i had ten button on my form
and when i click button
and then click on another button swap button's location
so when we run the application we do't know what the two buttons will be clicked
so how to programming this situation

You can identify buttons with the Name property. You can relocate them with the Left and Top properties.

FOR EXAMPLE i want to return button2 name during runtime to use it

Use the Name property, e.g. button2.Name.

This is extremely complicated. In order to get the name of a control, you have to use a property. To get access to a property you first have to access the control, which is done by writing the name of the control into the code. Then you put a period after the name. Not before or in the middle of the name, but after the name. This is very important. Then you have to specify what property it is that you want to access, and that is done by writing the name of the property after the period. To get the right property, you have to know the name of that exact property. In this case you want the property that returns the name of the control, which for some strange reason has been called Name. So by typing those four letters after the period, you gain access to the value that the property returns.
Now, have a go at putting this complicated code together, and come back with any questions you might have.

I use the Visual Studio 2005. Now I want to use different Resource.resx and Settings.settings. With the configmanager I want to select the Resource.resx and Settings.settings.

For to get a different resx u can load from a file
System.Resources.ResXResourceSet resxSet = new System.Resources.ResXResourceSet("C:\\...");
for to load Setting I can't remeber now

This code runs fine.
When it's run, output says Struct A's size is 16 and Struct B's size is 12, even though
both contain 2 ints and 2 chars each.
Can someone tell me how the heck that is possible?
#include "stdafx.h"
#include <iostream>
using namespace std;
struct
{
char c1;
int i1;
char c2;
int i2;
}a;
struct
{
int i1;
int i2;
char c1;
char c2;
}b;
int main()
{
cout<<"sizeof struct A " <<sizeof(a);
cout<<"sizeof struct B " <<sizeof(b);
getchar();
return(0);
}

Although you posted in the wrong forum, I will try to answer your question.
A char is aligned on a two byte boundary and an int is aligned on a four byte boundary. The structs will be padded with unused bytes to align the values.
This represents the memory layout of the structs, where _ represents an unused byte:
a: c___iiiic___iiii<br />
b: iiiiiiiic_c_

Hi,
I agree in general, but your "A char is aligned on a two byte boundary" surprised me;
I expect it to be true in C# (because char=2B), and false in all C compilers I know.
Normally variables get aligned on a multiple of their natural size, hence 1 for char
in C/C++. Is it different in C++ ? or is Microsoft doing special things, if so
what would be the main reason for this ?
Best regards.

You are right, a char is not aligned on a two byte boundary. The b structure will of course be aligned as this:
b: iiiiiiiicc__
The structure is aligned on a word (32 bit) boundary.
The alignmment is all up to the compiler. If it was more efficient to access a byte at an even word address, it would probably have aligned it like this:
b: iiiiiiiic___c___

Hi all. I am using daReport to create a report and i need an image on the report. I thought it would be as easy as sending the image name: "Test.jpg" as a parameter to the xml file and daReport would use that as the the image name. but no such luck as yet.
The parameter name is logopath:
<parameter name="logopath" />
i tried to use it like this...
<pictureBox x="457" y="26" width="314" height="130" strech="true"><br />
<file>$P{logopath}</file><br />
<border width="1" color="Transparent"></border><br />
</pictureBox>
This then shows a blank spot where the image should be.
i used the same for a text field...
<textField x="601" y="206" width="100" height="23"><br />
<text horAlignment="Left" verAlignment="Top">$P{logopath}</text><br />
<font family="Tahoma" size="10" ></font><br />
<foregroundColor color="Black"></foregroundColor><br />
<backgroundColor color="Transparent"></backgroundColor><br />
<border width="1" color="Black"></border><br />
</textField>
This worked fine as it showed the text: "Test.jpg". How would i use this text as the image name?
Thank you in advance.

Won't the author of daReport be the best bet for an answer to this question?
the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer
Deja View - the feeling that you've seen this post before.

okay... i just thought that someone might have used it and would know the answer. but i will ask the author.
Thank you anyway.

Hi all,
I seem to be having a problem with the configuration of my setup project.
Everything installs fine, however when the user launches the application for the second time after installation (via an icon on their desktop or start menu), the application first rechecks the MSI from which the application was installed.
I simply cannot find what has caused this to occur, and this will likely become a significant issue for the end users if they delete the original MSI package (this results in a failed attempt to find the package and subsequent failure to launch the application).
Any ideas as to what I've done wrong?
By the way, the source application is compiled from a mixture of C# and VB.NET projects - not sure if this is of any help.
