如何给数据窗口的picture object赋值

不用文件读取，从数据库取位图文件
付值到数据窗口的picture控件上
就是把位图复制到数据窗口的控件上
多谢!

用他应该是不行的，你最好用ole控件。

OLE方法!
先写临时文件，
再DW_MODIFY("xxxx.XXX='CC'")
试试吧!

能把位图文件取出来，但无法blob变量传到数据窗口的picture控件上

blob lb_blob_var
selectblob tz into :lb_blob_var from dzhd where bh = :bh and bdsdm = :bdsdm using sqlca;
if isnull(lb_blob_var) then
p_1.visible = false
else
p_1.setpicture(lb_blob_var)
end if

这是窗口的picture控件，

我说的是数据窗口的picture控件

你将picture控件放到数据窗口的上面，就可以了

看来只能先存成文件，再p_1.filename=""了

好说，要放在DW中还不好办吗？在窗口的constructor事件中写入setparent(handle(p_1),handle(this)),不就将p_1放入DW中了吗？其中api setparent的申明如下：function long SetParent(Long hWndChild,long hWndNewParent) library "user32.dll"

真的可以吗？打印时能一起打出来吗？

运行时报错，跟pb版本有关么？我用的是pb5
能再详细说明一下么？多谢!

谢谢大家我终于想通了：））

用下面的方法可以打印再一起了

long job

job = PrintOpen( )
PrintDataWindow(job, dw_name)
printbitmap(job,bitmap,x,y,width,height)
PrintClose(job)

暂时结贴，又办法还可以再讨论，
多谢大家了!

当然可以,试一试function long SetParentA(Long hWndChild,long hWndNewParent) library "user32.dll",其中参数可以使用handle(对象名称)来传递!
