This is the code I have been writing. For any conversion from bmp to any other image format it works,from jpeg to gif , bmp or png files it works. But when I try a conversion from jpeg to tiff , this is the exception I kept receiveing and I can't see what it refers to:
Invalid parameter used.
at System.Drawing.Image.Save(String filename, ImageCodecInfo encoder, EncoderParameters encoderParams)
Does anyone has a clue or met a similar problem.Thanks
/*----------Beginning of the code-----------------*/
Bitmap bBitmapTemp = new Bitmap(bBitmapIm);<br />
imViewerSetCompression ("image/bmp", sfname, bBitmapTemp);<br />
<br />
imViewerSetCompression ("image/tiff", svdasFileName, bBitmapTemp);<br />
<br />
private void imViewerSetCompression (String sMimetype ,String sfilename, Bitmap myBitmap)<br />
{ <br />
ImageCodecInfo myImageCodecInfo;<br />
Encoder myEncoder;<br />
EncoderParameter myEncoderParameter;<br />
EncoderParameters myEncoderParameters;<br />
<br />
myImageCodecInfo = GetEncoderInfo (sMimetype);<br />
myEncoder = Encoder.Compression;<br />
myEncoderParameters = new EncoderParameters (1);<br />
myEncoderParameter = new EncoderParameter (myEncoder,(long)EncoderValue.CompressionLZW);<br />
myEncoderParameters.Param[0] = myEncoderParameter;<br />
myBitmap.Save (sfilename, myImageCodecInfo, myEncoderParameters); <br />
}

<might help>
make sure the result of the GetEncoderInfo(mimetype) gives a compatible codecinfo.
Namely you can compare your codecinfo instance with the one built by GDI+ by trying a direct call to GdipGetImageDecoders(...).
</might help>
(the reason is that behind the wheel the run-time uses GDI+ and these calls to obtain the infos : there might be a bug (in which case you could help yourself by interoping GDI+ directly); or you might make an approriate use of the System.Drawing.Bitmap logic).

I'm developing a control derived from the ListView control and need it to find it's position relative to the Form it's contained on.
In my test Form I have the ListView positioned on a TabPage, and all the normal positioning references (this.Bounds, this.Location, this.Top, this.Left, this.ClientRectangle etc) return 0 - which is it's correct position within the TabPage, but obviously has nothing to do with it's position on the parent Form.
Note that I do not need a reference to it's Screen location, just the X and Y coordinates to it's upper-left corner within the parent form - can anyone help?

you need to offset the location by adding the parent location.
int x = Left;<br />
for (Control thisParent = parent; thisParent != null; thisParent = thisParent.parent)<br />
x += thisParent.Left;

Many thanks for the quick reply!
I tried implementing your suggestion as follows:
int x = Left;<br />
for (Control thisParent = Parent; thisParent != null; thisParent = thisParent.Parent)<br />
x += thisParent.Left;<br />
<br />
int y = Top;<br />
for (Control thisParent = Parent; thisParent != null; thisParent = thisParent.Parent)<br />
y += thisParent.Top;
No go though I'm afraid - what that ends up giving me is a screen reference, not a refence relative to the containing form. Perhaps it has something to do with the fact the the test app is MDI? Even if so, I'd like to make a control that will work reliably in both SDI and MDI apps.

just stop one level earlier
int x = Left;<br />
for (Control thisParent = Parent; thisParent != null; thisParent = thisParent.Parent)<br />
{<br />
if (this.Parent != null)<br />
x += thisParent.Left;<br />
}
"When the only tool you have is a hammer, a sore thumb you will have."

Thanks for the tips Philip - after stopping one level before the MDI parent I still had a problem where the MDI child form was reporting negative location values. The final code I came up with looks like this:
int x = Left;<br />
for (Control thisParent = Parent; thisParent != null; thisParent = thisParent.Parent)<br />
{<br />
if (thisParent.Parent != null && thisParent.Left > 0)<br />
x += thisParent.Left;<br />
}<br />
<br />
int y = Top;<br />
for (Control thisParent = Parent; thisParent != null; thisParent = thisParent.Parent)<br />
{<br />
if (thisParent.Parent != null && thisParent.Top > 0)<br />
y += thisParent.Top;<br />
}

Hi,
I'm not too sure how to explain what I'm trying to do. Basically I want a developer to go "File | Add New Item" and choose an option like "Paul's XMLDB Form". This will then prompt the user for a connection string to a DB where it should store the form definition, and create a "form" in design view for them to edit. I've made some custom controls that I want the developer to be able to add to the form. I'd like the editing to look as close to the standard form editing in VS.Net, and when they choose to save it, it will write the definition off to the DB as an XML field.
Now I've tried looking at Designers, IDesignerHost, IRootDesigner, ComponentDesigner, etc, etc. But I'm not finding an easy way to do this. I thought I'd create my own add-in, which docks a window in VS.Net but now I can't get the toolbox to activate so I can drag components off it.
Does anyone know how I could do this?
Thanks
From
Paul

Can anyone point me in the right direction. We are developing an application in C# and would like to create a framework where 3rd party developers can develop forms in HTML/JScript and be able to plug them into our application.
We are developing a CRM system. The main framework will obtain data from the database and then if the user wants to access this 3rd party form, we will load the form in an embedded IE. What we would like is for the JScript inside this page to be able to access our internal object and access the same data that the rest of our framework has access to.
I know that I can access my object as a COM object from within the script, but that would be a different instance of my object.
The other possibility is to have the framework call a known function within the JScript and make itself know.
We are at very early stages of this project. Can you suggest resources where I can find more about this integration? Do you think this scheme is workable?

Not sure of the exact criterion you have, however BCP works extrememly well when dealing with really large datasets. We used it with SQL Server 2000 often.

I am trying to compile a project using the command line compile and I am running into a problem. I have two forms (Form1.cs and Form2.cs) Form2 includes an IE WebBrowser (AxSHDocVw.AxWebBrowser). The program compiles and runs fine when compile within VS.Net; however, when I use csc.exe I compiles, but when I try to run the form with WebBrowser embedded in it, I receive
“Could not find any resources appropriate for the specified culture (or the neutral culture) in the given assembly. Make sure “Form2.resources” was correctly embedded or linked into assembly “xxx”"
I used the following lines to compile:
> <code>resgen Form1.resx</code>
> <code>resgen Form2.resx</code>
> <code>csc /t:winexe /out:xxx.exe
/r:Interop.SHDocVw.dll
/r:AxInterop.SHDocVw.dll
/r:Microsoft.mshtml.dll
/resource:Form1.resources
/resource:Form2.resources
Form1.cs Form2.cs AssemblyInfo.cs</code>
Any suggestions are welcome.
