I am using Visual C# 2005 to develop a program. When the program calls line 3 of the following code I get a COMException with every path I try. I am trying to place a shortcut in the start menu.
The problem code is underlined. Even when that method is called by itself it creates the exception. I have included the proper reference in the project. Any ideas? Thanks for any help.
WshShell shell = new WshShell();
string path = Environment.GetFolderPath(Environment.SpecialFolder.StartMenu) + "\\programs";
IWshShortcut link = (IWshShortcut)shell.CreateShortcut(path);
link.TargetPath = destinationPath + "\\filemover.exe";
link.IconLocation = destinationPath + "\\" + "FileMover.ico";
link.Save();

Question #1: Event Handler External to the Main Form
An application that I am working on requires an eventhandler class stored in another folder separate from the main application form. The problem that this creates is that I have been forced to have two event handler approaches for the controls: one for the event processing and another to manipulate the form controls. I would much rather prefer to combine the two event handlers into one event handler to remove the confusion rather than have to manage two of them.
The reason why I cannot put all of the code thus far into the external event handler is because none of the form objects are available in the external event handler class. In other words, I would need to manipulate elements that are on the form from the external event handler. However, the external event handler does not even permit the keyword "this" to be used, especially when the methods in the external event handler is set to static. If the keyword static is removed, then the keyword "this" works, but only for the elements that are on the external event handler class. I cannot manipulate any of the form elements from the external event handler class.
The first question is: How to I address the main form of the application from the external event handler class. I tried to use:
<br />
frmMainForm frm = new frmMainForm();<br />
but that only created another form. When I tried to manipulate the controls on the form, and the event handler interacted with this "new" form, it caused the form controls to disappear. I suspect that the control disappeared from the original form because it did not know what to do with it, considering that now there was a "new" frmMainForm form. Either that or it actually attempted to move the control from the "original" frmMainForm to the "new" frmMainForm, but I doubt it because that would require some other technologies.
I also used the "using" keyword referencing the namespace of the frmMainForm form. Then where the code required the frmMainForm I tried to reference it with
<br />
System.Windows.Forms.Form frm = NameSpaceOfFrmMainForm.frmMainForm.ActiveForm;<br />
but when the program reached this line of code, it only caused the form to become "active" thereby ignoring any of the code following it which attempted to use the form controls from the application's main form. I know that I am missing something. Could somebody kindly explain to me how to address the application's main form from an external event handler class?
Question #2: ctrl.Update()
When drawing a control to the screen in a looping construction of an array, I would like to clean the screen from the previous iteration through the loop. For example:
<br />
System.Drawing.Point pt1 = new ctrl.Location(50, 10);<br />
System.Drawing.Point pt2 = new ctrl.Location(50, 20);<br />
System.Drawing.Point pt3 = new ctrl.Location(50, 30);<br />
System.Drawing.Point pt4 = new ctrl.Location(50, 40);<br />
<br />
Point[] ptArray = {pt1, pt2, pt3, pt4};<br />
foreach (Point pt in ptArray)<br />
{<br />
ctrl.Location = pt;<br />
ctrl.Update();<br />
}<br />
The problem is that each time through the array loop, the control displays, but the previous time through the loop is not removed. Is there some kind of Form1.Paint() delegate that could be used to clear the previous control image ghost? I would like the control to appear as if it is moving with an animation effect, but the fact that the previous ctrl.Update() remains on each next time through the loop detracts from the desired result. Would really appreciate some assistance!!!

Because every time you do a complete rebuild of the application, the output directories get cleaned out. You might want to try putting the .INI file either in the application project folder or where the application can find it on the Path, like in the %WINDIR% folder, which, BTW, is not always C:\WINDOWS.
By putting it in the application project folder, this folder will not get cleaned out when you rebuild your project. If your code is written correctly, it will not assume that the current directory is whatever directory the app was launched from. Instead, your code should ask the system from what directory is was launched from, then look in the directory for the configuration file.
Check into storing Application.StartupPath and/or Environment.CurrentDirectory when your application starts and using it later to locate your configuration file.

hi
I want to use the .exe.config file. I copied to the main project folder. Then also it is not reading the file. Please tell me from where all the application reads the exe.config file. Secondly, I created an .ini file also.
I copied .ini file to bin, debug and project folder. I set the project output folder to first to bin then to debug. But the problem remains.
please help

Actually this is not true. I have multiple applications that have INI files in the Debug & Release directories and they are not effected in any way when performing any build type in the build menu of VS.NET. Are you talking about some action other than those in the build menu ?

Hi David,
thanks a lot for your fast answer.
I already use PIA, but the code is different in C# from VB6.
Since 2 days i try to "translate" this sample VB6-code to C# but i have no success.
I really become crazy with this problem.
Peter

ok. I think best you can do is to browse MSDN for examples...
You can post here result of you translation (if not long), maybe somebody can point out what's wrong or how to do it etc...

Here is a function to copy from a presentation all elements and make a new presentation of it.
For each element of a shape a new shape is generated.
But the problem is that it loses all its formatting for the text, background,...
Perhaps anybody has an idea.
Thanks a lot!
Code:
public PowerPoint.Presentation GetPresentation(PowerPoint.Presentation pOriginalPresWithAnimations) {
PowerPoint.Presentation pNewPresWithoutAnimations = __pPPT.Presentations.Add(Office.MsoTriState.msoTrue);
string sName = pOriginalPresWithAnimations.Name;
string sPPTCopyPath = "PresentationCopy";
string sPath = System.Windows.Forms.Application.ExecutablePath;
sPath = Path.GetDirectoryName(sPath);
sPPTCopyPath = Path.Combine(sPath, sPPTCopyPath);
string sSlidePathName = Path.Combine(sPPTCopyPath, sName);
if(!Directory.Exists(sPPTCopyPath))
Directory.CreateDirectory(sPPTCopyPath);
if (File.Exists(sSlidePathName))
File.Delete(sSlidePathName);
pNewPresWithoutAnimations.SaveAs(sSlidePathName, PowerPoint.PpSaveAsFileType.ppSaveAsPresentation, Office.MsoTriState.msoTrue);
foreach (PowerPoint.Slide pSlide in pOriginalPresWithAnimations.Slides) {
SlideInfo pSlideInfo = PresentationInfo.GetInfos(pSlide);

Is there a c# equivalaent of the delphi WITH keyword? WITH allows you to set a scope for class variables in a function, so that the class need only be specified once then all variable names that match with variable names inside the class are deemed to be from the specified class. ie.
public class car
{
public int wheels;
public bool isSofttop;
}
public main
{
car Audi = new car;
WITH Audi do
{
wheels = 4;
isSofttop = false;
}
}

AFAIK no, there isn't equivalent to with. If you want to be 100% sure, google for ECMA-334(C# spec.) After quick glace into spec. there seems to be nothing similar to with statement.
Personally, I am happy about.
However you can use using to deal with namespaces. (which are often way much longer names)

The closest you can get to that is to use a temporary abbreviated variable:
public main
{
car Audi = new car;
car a = Audi;
a.wheels = 4;
a.isSofttop = false;
}

Hi ,
I want to filter the selected color from the image.I had already done the filtering the whole image with grascalling and making contrasting whole image but now i want to filter the image with selected color,Now i want to know logic for filtering the selected image.
here i am using the logic for contrasting the image (means filtering the whole image),now can anybody say how to deduct or filter the selected R,G,B value from the whole looping.Here i am describing whole loop which i am using for contrasting the image.
public void MakeContrastUnsafeFaster(int nContrast)
{
//Getting the how much pixel Arrays do you want to retrives.
Point size = PixelSize;
//Locking the bitmap for getting great performance
LockBitmap();
for (int y = 0; y < size.Y; y++)
{
PixelData* pPixel = PixelAt(0, y);
for (int x = 0; x < size.X; x++)
{
byte value = (byte) ((pPixel->red + pPixel->green + pPixel->blue) / 3);
// perform contrast enhancement here:
value = (value < 150 ) ? byte.MinValue : byte.MaxValue;
pPixel->red = value;
pPixel->green = value;
pPixel->blue = value;
pPixel++;
}
}
//Now Unlocking the Bitmap and making it free.
UnlockBitmap();
}
Here i am setting the R,G,B value with minimum and maximum value which bifercare my image into only black and white,
Now my requirement is that what to do in this logic by which only selected color dropped out?
anybody help into that?

How can one define a class in multiple files?
Sometimes there are classes with huge amount of code that wouldn't have sufficient reason for a hierarchy of classes (as the main class of a web service) but still are difficult to maintain because of the large amount of code in one file and even more difficult to be used by multiple developers in the same time. So, is there a way to span a class over multiple files?
Cheers
Dani
