Introduction

Looking at the .resx file that VS.NET uses to store resources such as images, I thought wouldn't it be cool to have a XML file where you can store images and other info for you app and at startup your app gets the look and feel from the XML file dynamically. You can then change the look and feel by changing the XML file, maybe over the internet! A little investigation showed that .NET namespace System.XML has 2 great classes XMLTextWriter and XMLTextReader which does all the hard work for you with their Read/WriteBase64 methods.

m_XMLWriter.WriteStartElement("",NodeName,"");

<code>m_XMLWriter.WriteBase64(ImageBinaryBuffer,0,ImageBinaryBuffer.Length);

m_XMLWriter.WriteEndElement();

So here is my quick and dirty app, which uses 2 classes CLookXMLReader and CLookXMLWriter to do the putting in the binary and getting the binary out to bitmap or an icon. You basically use the Writer to put the images into the XML, then the reader can be used at a separate app to get the images out from the XML. Made the code a bit messy when reading the binary out from the XML, there must be a better way to it, please let me know! I hope you dont judge coding skills by just looking at this app only (I am usually much better!) :)

How to convert .ai file(Adobe Illustrator File) to .bmp(BitMap) file in c# Santhosh_B_K 2:08 16 Apr '07   How to convert .ai file(Adobe Illustrator File) to .bmp(BitMap) file in c# Sign In·View Thread·PermaLink 3.00/5 how do I pass an image from nodes in the xml to a component on a form Try74 2:15 8 Jan '07   I am trying to pars an XML file where there is an image associated with the componenet.

I can load an image and save it as XML, ok. I can then load the XML and extract the image, ok But then when I try to save it as XML again and get the error: "An unhandled exception of type 'System.Runtime.InteropServices.ExternalException' occured in system.drawing.dll Additional information: A generic error occurred in GDI+." Any ideas? The image is a jpg, and is stored in a memory stream. Sign In·View Thread·PermaLink 1.67/5 XmlTextReader and binary data Anonymous 5:45 10 Dec '02   Hi, I have and XML document, dtd and xsl file stored as blobs within an Oracle database. I am using the following code within my web service to retrieve the blobs from the database, however I have no idea how to then load them into the XMLTextReader. Presumably the data returned in the dataset will need to be converted from binary into something the XMLTextReader will understand. I'm pretty new to .Net and would appreciate any help as I'm tearing my hair out over this one!! My existing code: string sSQL = "SELECT THE_FILE, THE_DTD, THE_XSL from WSTest"; OracleDataAdapter oDA = new OracleDataAdapter (sSQL,myConnection); OracleCommandBuilder oCB = new OracleCommandBuilder(oDA); DataSet oDs = new DataSet("WSTest"); oDA.MissingSchemaAction = MissingSchemaAction.AddWithKey; oDA.Fill(oDs,"WSTest"); DataRow oDR; oDR = oDs.Tables["WSTest"].NewRow(); oDR = oDs.Tables["WSTest"].Rows[0]; Thanks, Sharon Sign In·View Thread·PermaLink 3.50/5 dbconsts.obj Reza_Y 23:07 20 Sep '02   Hi.

Sign In·View Thread·PermaLink Sending the image size Vinla 1:24 20 Sep '02   I noticed in the code to this article that the author was looking for a better way to create the right size of byte array in which to store the image data when reading in the image from the xml. I dealt with this by including a size attribute in the xml element containing the image data i.e. <imagedata size="284375">[image data]</imagedata> You can then read this value just before extracting the data int size = Int32.Parse(xml.GetAttribute("size")); byte[] imageData = new byte[size]; xml.ReadBase64(imageData,0,imageData.Length); Sign In·View Thread·PermaLink 1.00/5 Bitmap to a bytearray jeetu 5:44 26 Aug '02   If I already have the image loaded in memory, is there any way for me to get it shoved into a byte array?

Kamen Nikolov kamen.nik@sympatico.ca Sign In·View Thread·PermaLink Re: Bitmap to a bytearray Kamen Nikolov 7:55 26 Sep '03   If you have the image as an image object and not as an XML node, then use this: MemoryStream memStream = new MemoryStream(); bitmapObject.Save(memStream, System.Drawing.Imaging.ImageFormat.Gif); int ImageSize = Convert.ToInt32(memStream.Length); byte[] ImageBytes = new byte[ImageSize]; memStream.Position=0; memStream.Read(ImageBytes, 0, ImageSize); memStream.Close(); return ImageBytes; Sign In·View Thread·PermaLink Xml bunary vb6 problem in c# bcapuano 13:25 30 Jul '02   In vb6 with msxml3 i do the following code : Set oElement = xmlDOMDocument.createElement("SIGNATURE") oRoot.appendChild oElement oElement.dataType = "bin.base64" oElement.nodeTypedValue = rsResult.Fields("Signature").Value to assign binary data from one recordset to a MSXml Node I try to do the same in C# using System.Xml, but i want a source code that don't use temprary files.

CString strDataType = "bin.base64"; BSTR bstrDataType =strDataType.AllocSysString(); m_pCurrentNode->put_dataType(bstrDataType); SysFreeString(bstrDataType); VARIANT vtype; vtype.vt = VT_ARRAY; m_pCurrentNode->get_nodeTypedValue(&vtype); Sign In·View Thread·PermaLink 2.00/5
