Bitmap FromFile space "file not found"


I am using aspose.slides to create PPTx's. Some of the process involves loading jpg's from another server and including them in the presentation. This works fine in my development environment. When I upload the site to its server, the jpg loading fails.

I am trying to access jpg's on the other server by:

   oFS = New FileStream(sFile, FileMode.Open, FileAccess.Read)

This causes an access violation error when run from the server.

I also boiled the code down to reading the file directly:

   oImg = System.Drawing.Bitmap.FromFile(sFilePath)

This causes a file not found error.

We have narrowed the problem down to the fact that the File Path has a space in it. How does one solve this problem (while still keeping the space, there is a lot of legacy data)? I have tried replacing the space with %20 or +. I have tried using Server.UrlEncode. The error message always comes back with the encoding in place (like no decoding

Bitmap to Image Control - ImageUrl


 This is my first attempt at using the drawing features of asp.net.  I just want to start simple, and create a single color bar based on a value for a single graph.  I wrote this so far, but I can't figure out how to take the bitmap I just created, and apply it to the Image Control. Do I have to save the file first, and then reload it.

Plus, my box keeps coming out pure black, I trying to fill the box with a color. 

This is part of a web custom control, in which I dynamically created an Image Control. I want to apply the bitmap I made to the image control. 


Dim imgGoogle As Image
imgGoogle = New Image
imgGoogle.ImageAlign = ImageAlign.AbsMiddle
imgGoogle.ImageUrl = cs.GetWebResourceUrl(rsType, "ice5software.BotCatcher.Google.gif")
Private Sub DrawBarGraph_Google(ByVal BarValue As Integer)

	Dim objBitmap As System.Drawing.Bitmap
	Dim objGraphics As S

Invalid length for a Base-64 char array for my coding in ASP.net C#. How to solve it ?


Hi Friends ,

I have done encrypted password and decode but i got error  like  this  " Invalid length for a Base-64 char array" .

Pls help . Thanks


psswd = txtPassword.Text;

pwed = base64Decode(psswd);

public string base64Decode(string sData)
            System.Text.UTF8Encoding encoder = new System.Text.UTF8Encoding();
            System.Text.Decoder utf8Decode = encoder.GetDecoder();
            byte[] todecode_byte = Convert.FromBase64String(sData);
            int charCount = utf8Decode.GetCharCount(todecode_byte, 0, todecode_byte.Length);
            char[] decoded_char = new char[charCount];
            utf8Decode.GetChars(todecode_byte, 0, todecode_byte.Length, decoded_char, 0);
            string result = new String(decoded_char); return result;

encoding/decoding a string to/from bitmap


I have two methods:

Encode - takes a string, converts it to array of bytes, uses bytes to specify colors, creates a color and sets a pixel based on bytes

Decode - takes a pixel, retrieves color (R,G,B) bytes and converts them to characters, that produces a string which was previously encoded

I'm using two for loops (img height/width) to specify position and access pixels

The issue is that once display (Control Panel\Appearance and Personalization\Display) changes to anything other then "Smaller - 100%",
bytes have different values during decoding, thus different string is produced (corrupted).

If the setting is set to "Smaller - 100%" the results are normal.

What can I do to avoid that problem?

Thanks in advance

Linq2Sql error: "Invalid attempt to call Read when reader is closed."


I've read up on this error from other posts and on other sites, but haven't found a solid resolution to the issue yet. My setup is as follows:

I have a RepositoryBase class that fields certain db calls that all repositories need to perform. In one such call, "GetSecurityGroup", it works most of the time, but will seemingly at random throw an exception with the error "Invalid attempt to call Read when reader is closed." All other Repository classes inherit from this one, and they all use the same DataContext object, which I understand isn't thread safe. Since there could be multiple calls to the DataContext object on the same page, perhaps one is using the DataContext when the next tries to do so. I'm not sure. What can I do to ensure this doesn't happen?

Invalid URL"" after copy or move a document.



We have an website that have 3 libraries. The "first Library" is used only to edit documents and it's called "my documents". When a user finish of edit your documents here, they start a workflow that will check fields in the document and move the document for the second library (using Sharepoint Designer Workflow - without custom actions).
In "second library" we have a big workflow. This WF has some steps for approve, collect feedback, generate sub-tasks and others things related for the document. This WF use many custom actions in (Sharepoint Designer).
When this WF arrives to the end, the document is moved to "third library", that is a official repository of documents in the enterprise.
The entire cycle works fine. But when someone creates a internal copy of the document in the "first library" to begin again the flow, we receive a Invalid Url error. It occurs when any update operations is executed over the document item, the value is conserved but the error is displayed. After it, we can not execute other workflows over the item.
If we save the document in local disk, delete the library item, and then upload it again, the problem is solved.

Some one have an idea about why and how solve it?  We are using WSS 3.0.

User group invalid for new document



Defined a user group and a site column of type people/group directing to this group.

Also defined a content type and added the site column to this content type.

When I create a new word document of this content type, word opens displaying my site column ok. But when I enter it, I see that all active directory (AD) entries are displayed. I want it to display only those users I added to the user group I created. Moreover, users can select any user from AD, which makes defining a user group and a site column meaningless.

This problem is only in creating new documents with Word. If I edit properties of an already existing document in my site, everything is ok: I can select only the users in the group.


Invalid web service call, missing value for parameter: \u0027prefixo\u0027 (AutoCompleteExtender)


Good afternoon.

I'm trying to put an AutoCompleteExtender working, but i'm having an error, that i discovered with Fiddler, that is the reason that the autocomplete doesn't work:

Writing Bitmap to Response.OutputStream - Generic Error Occured in GDI+



This is what I'm trying to do when I get the error on the server (it works on my local machine):

System.Drawing.Image image = System.Drawing.Image.FromFile(filepath);
System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(image); 

Response.ContentType = "image/bmp";
bmp.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Bmp);

I don't think it can be a permissions problem because this works on the server:

System.Drawing.Image image = System.Drawing.Image.FromFile(filepath);
System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(image);

Response.ContentType = "image/jpeg";
bmp.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg);

So how do I get this to work for a bitmap?
