另一个“在GDI +中发生一般错误”。错误 [英] Another "A generic error occured in GDI+" Error

问题描述

Hello All，


我在VB.NET表单上有一些链接到AccessDB的图片框。如果

用户希望打开或编辑图像，我需要将图像保存在临时文件中，然后在任何查看器/编辑器中打开该文件

是用户系统的默认值。我试图做

picturebox1.image.save（filename），这导致GDI +中发生了一般错误

。


但是，如果我使用未绑定的图片框，请执行

picturebox2.image = image.fromfile（filename1），然后执行

picturebox2.image .save（filename），它运行正常。


我的GDI +错误不是由权限问题引起的，因为我使用了

相同绑定和未绑定图片框的文件夹。它似乎与图片框从数据库中检索图像信息

的方式有关。有办法吗？


问候和TIA，

Lee

解决方案

对于未在Access中保存的图像，可能值得尝试相同的实验。

它在图像信息前面存储一个78字节的标题。不确定这是否导致问题，但希望缩小原因。

Hello All ，

我在VB.NET表单上有一些链接到AccessDB的图片框。
如果用户希望打开或编辑图像，我需要将图像保存在 viewer / editor是用户系统的默认设置。我试图做
picturebox1.image.save（filename），这会导致GDI +中出现一个通用错误。

但是，如果我使用的话未绑定的图片框，做一个
picturebox2.image = image.fromfile（filename1），然后做一个
picturebox2.image.save（文件名），它工作正常。

我的GDI +错误不是由权限问题引起的，因为我正在使用
绑定和未绑定图片框的相同文件夹。它似乎与图片框从数据库中检索图像信息的方式有关。有没有办法解决这个问题？

问候和TIA，
Lee

嗯，这就是什么我在想，因为未绑定的图片框可以将

图像保存到文件中，但绑定的图片框（对Access）不能。但是，在过去几分钟（在我的原始帖子之后）的

中，我发现存在于AccessDB中的某些图像将保存，而不会出现GDI +错误。


比较将从图片框中保存的图像与不会的图像：


无错误图像：

JPG 150x150（小图）

错误图片：

JPG 1024x768（大图）


我'我将创建一些不同版本的图像，产生

GDI +错误，看看我是否可以弄清楚限制是什么（可能是像素

HxW，也许是文件大小，可能是方面，也许颜色深度等）。只是一个FYI，

AccessDB中的所有图像，除了一个，都会导致GDI +错误。


如果有人遇到此问题，请让我知道（因为我不想

浪费太多时间进行实验，如果已经有一个已知的解决方案！）

您可以使用Access来启动图像即，双击该字段。然后，

使用启动的任何查看器（可能是iexplore）将文件保存到新的

位置。

返回Access表格，使用新文件添加一个新行。

执行此操作的原因是需要显示一个已知的好图像，因为您可以在IExplore中看到它（因为您在IExplore中看到它），由

单独的应用程序保存到磁盘，并添加到Access中的新行，可能排除

与记录有任何异常。

Hello All,

I have some pictureboxes on a VB.NET form that are linked to an AccessDB. If
the user wishes to open or edit an image, I need to save the image in the
picturebox to a temp file, then open that file in whatever viewer/editor is
the default for the users system. I tried to do
picturebox1.image.save(filename), which results in "A Generic error occured
in GDI+".

However, if I use an unbound picturebox, do a
picturebox2.image=image.fromfile(filename1), then do a
picturebox2.image.save(filename), it works fine.

My GDI+ error is not being caused by a permissions problem, as I''m using the
same folder for the bound and unbound picturebox. It seems that it has
something to do with the way the picturebox retrieves the image information
from the database. Is there a way around this?

Regards and TIA,
Lee

解决方案

It might be worth trying the same experiment on an image not held in Access.
It stores a 78 byte header in front of the image information. Not sure if
this is causing the problem, but hopefully narrows down the cause.

Well, that''s what I was thinking, since the unbound picturebox can save an
image to a file, but the bound picturebox (to Access) can not. However, in
the past few minutes (after my original post), I found that there are
certain images stored in the AccessDB that will save without the GDI+ error.

Comparing an image that will save from the picture box to one that won''t:

No error image:
JPG 150x150 (a small image)
Error Image:
JPG 1024x768 (a big image)

I''m going to create some different versions of the image that produces the
GDI+ error and see if I can figure out what the limitation is (maybe pixel
HxW, maybe file size, maybe aspect, maybe color depth, etc.). Just an FYI,
all of the images in the AccessDB, except one, cause the GDI+ error.

If anyone has run into this before, please let me know (as I don''t want to
waste too much time experimenting if there''s already a known solution!)

You could use Access to "launch" the image ie, double click the field. Then,
using whatever viewer is launched (probably iexplore) save the file to a new
location.
Go back into the Access table and add a new row using the new file.
The reason for doing this is it takes a known good image that can be
displayed (because you see it in IExplore), that is saved to disk by a
separate application, and added to a new row in Access, possibly ruling out
anything strange with the record.
