How to insert/remove image in a table from Form

According to the Requirement we insert the images in to the Tables through forms.For this we use “getData()” method of the “Bin Data” class

Here i found the 2 scenarios

scenario 1;- 
Create a field in table of Type contianer which must extend EDT:Bitmap

public Bitmap getImage()
{
Bitmap bitmap;
Bindata     binData ;
FileIOPermission perm;
FilePath _filepath = “c:\\sample.jpg”
;
perm = new FileIOPermission(_filePath, ‘r’);
perm.assert();

binData = new BinData();
if (binData.loadFile(_filepath))
{
bitmap = binData.getData();
}
CodeAccessPermission::revertAssert();

return bitmap;
}

after that you assign this method to contianer  = > table.Field = class.getImage()

scenario 2;-

Create a field in table of Type container which must extend EDT:Bitmap

void clicked()

{

FilenameFilter filter = [‘Image Files’,’*.bmp;*.jpg;*.gif;*.jpeg’];

BinData binData = new BinData();

str extention, path, nameOfFile;

Str imageFilePathName ;

super();

imageFilePathName = WinAPI::getOpenFileName(element.hWnd(),filter,”, “@SYS53008″, ”,”);

if (imageFilePathname && WinAPI::fileExists(imageFilePathName))

{

[path, nameOfFile, extention] = fileNameSplit(imageFilePathName);

if (extention == ‘.bmp’ ||

extention == ‘.jpg’ ||

extention == ‘.gif’ ||

extention == ‘.jpeg’)

{

binData.loadFile(imageFilePathName);

imageContainer = binData.getData();

element.showLogo();

Thy_InventSymbolsIcons.Image = imageContainer;

}

else

{

throw error(“@SYS89176″);

}

}

element.Query_cntRecords();

}

then if you want to remove an image :

void clicked()

{

super();

element.delete();

}

and the delete mehtod is defined as follows:

void delete()

{;

Thy_InventSymbolsIcons.Image = connull();

Thy_InventSymbolsIcons_ds.refresh();

}
