We are using the Handango signature capture control in a CF Pocket PC
application, and are saving the captured signature image in a SQL CE
database in the device. When we push this image to SQL server , and try to
access it using a PictureBox in a ASP.NET web application, we get a 'Invalid
Paramater used'. According to the MS known issue database, this is because
GDI+ expects atleast 32 bit resolution.

How do we convert the 24 Bit map image captured and stored in the device to
a 32 bit map image so that it is GDI+ compliant ? Hope you can give some
tips so we can use the signature captured, on the SQL Server...

Thanks, Chakravarthy
 
I don't think you need to do that. Either you're not saving/retreiving the
image data correctly in the database or the control is not producing the
correct image.
 
Hello all,

I have icons for listview in ImageList, also i have icons in picture box.
Source files (*.gif, *.jpeg) were added into this components at Design time.
Why it converts white color on images into another, it's ugliness. How i can
save white color on pictures?
