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.

i want to replace an item of array with another item
for example replca the value of arr[5] with arr[7]
ma_refay
|
|
|
|
|
object temp = arr[7];
arr[7] = arr[5];
arr[5] = temp;
|
|
|
|

This is done with a regular assignment:
arr[5] = arr[7];

or button15 with button7

You don't swap the buttons, you simply switch places on the buttons.
Get the value of the Location property from one of the controls and store in a temporary variable. Then get the value of the Location property from the other control and put in the Location property of the first control. Lastly, you get the value from the temporary variable and put in the Location property of the second control.

anybody plz tell me how how to use use mouse button-up & mouse button-down for drawing in paint program as we do in microsoft paint in windows....
|
|
|
|
|
The mouse move is the event that matters. You need to keep track of the co-ordinates it moves to, and use them to draw a line in your onPaint handler. You call Invalidate() to force a Paint event.

I am trying to create a application that when it is done updating the files that it need to it has the ability to delete itself. Is there a way of doing this, I thought that maybe if I could launch the program and run it entirely from ram that this would solve the problem.
So does anyone know how I would launch the program and run it from ram or is there a way to delete the executable when it is done?
|

Where else did you think your program is run from ? A program that is running, is in RAM, although the file is locked.

You may want to take a look at AppDomain.ShadowCopyFiles.
Simply speaking, with shadow copy enabled, the files holding your classes aren't locked anymore and thus can be deleted while their classes are still loaded in a running program.
