Thanks for the quick reply.

I expected I probably could just remove that code but was worried there may be other licensing issues.

I'll take another look at the tutorial.

Thank you.

We have the source version of TeeChart. I've just encountered an error whilst experimenting with trying to create a higher resolution image for reporting purposes. The function we called was DrawToBitmap which generated the following exception: "Please register your version of TeeChart to export to ...

I've just loaded up a sample project. Very crude but it shows the issue. If you right click and pan, it'll leave a ghost cursor. If you move the mouse cursor off the chart and then back on, it ghosts the first drawing of the cursor. Disabling the code that turns the cursors on and off when you enter...

Sure - perhaps it's similar though. It started happening in the last month or two. If FastCursor is off, everything works fine however if it's on then the first time I enter the chart or if I select a menu item from a popup, the first place the cursor is drawn leaves a ghost. I'll keep experimenting...

I'm having this problem with both the December release and the one before that. I thought it was our custom cursor code so I reverted to using the standard cursor tool in FastCursor mode.

Is it related to the new manual double buffering updates?

That's great, many thanks. We'll get the changes put in place as soon as we can.

Thanks for your excellent support.

I've posted an example... The project file is called: ChartOnPaint.rar The OnPaint handler is in DerivedControls.cs The function that writes the custom text is DrawHeaderAndFooterText. We're also doing a few other custom bits and pieces but I've tried to create a basic stripped down example that dem...

Hi, Firstly I wanted to mention that the latest update with the double buffering update is excellent. It’s nice and fast after it’s created the chart, no more sluggish windows. We have one minor problem as a side effect though which I’m hoping you can help with. We override the OnPaint handler to wr...

That's great. Many thanks.

Hi, I've figured out the problem. I can upload an example if you like but it's quite straightforward. When the series is created and the transparency is set (or is uses it's default), it can no longer be updated. e.g. I create three traces each at 90% transparency. If I then try and update the trans...

Yes, that does work fine.

Something has changed between the two versions that's made our main application no longer apply the transparency values.

The values are updated depending on which trace is selected. I'll try and run some tests to see if I can find any clues.

A quick followup... I found the backed up dll's in the Steema program files folder. I dropped those into the project folder and reran our application. Everything then worked fine so it does look like transparency has been broken between those releases. Either that or perhaps it's been dropped from t...

Hi, It's with the series transparency. We were using it to 'background' non-selected traces. Essentially we do the following for each line: line.Transparency = 80; It used to work fine but I just noticed in the current build that uses the latest release, transparency no longer works. I can downgrade...

I have a quick question regarding FastLine transparency. We had it working nicely until recently when we updated to the latest version: TeeChart for .NET [15 JUN 2007] I don't think we've changed anything but have noticed that the transparency value for the lines no longer appears to be applied. Has...

It's a shame the repaint causes the graph to be recreated.

If there's a way round it or I can help with testing, please let me know.

Many thanks.
