My task is to validate the digital signature against the x509 embedded key in the xml document. I see examples how to do this against a public key in the mdsn examples but not sure how to do the compare within the same xml block.

View 1 RepliesSmart Device Framework Signature Panel - Draw Signature In Full WinForms App
May 15, 2011I'm planning on using the Smart Device Framework 2.3 to use the signature control panel in a Windows Mobile 5 application using the compact framework 3.5.
The control has the option to save the signature as either a byte array of points, or as a bitmap. Now seeing as I want to store the signature in a sql compact database, I guess the byte array is going to be better. The trouble is, I'm not sure how to render that in a full WinForms application after I've transferred it back to the desktop.
I need to show the signature on a report, so it would need to be an image I could link/embed into the report.
VS 2008 Developing A Custom Component (single Signed Dll File)
Nov 26, 2011Im currently developing a custom logging component, that we will deploy with all our applications, windows services, webapps, windows apps etc. I have a few questions of various nature. The component is a single signed dll file:
1) Which is the "safest" way to get the current directory? For example, in the config file, in the config section I have a property "logpath". The application will read this and write a log file depending in what they write:
c:myapplog (it will write a log here, create whatever folders it need) /Log (directly under the installed app directory, like c:program filesmyappLog) Log (same as above) I need something that work with both windows and web apps, for webapps it will log under the virtual directory of the aspnet app.
2) For exception handling, if nothing special is happening, like in the DAL, I get a sql server exception, is there any point in using

VS 2010 Signed And Unsigned Integer NOT: For Hex File Checksum Computation?
Feb 22, 2012I have been trying to compute the checksum for a line of hex code. This is to create a hex file which will be loaded onto an embedded micro.Some of you guys may not know how this is done so very briefly:
a line of hex bytes:
: 10 01 00 00 21 46 01 36 01 21 47 01 36 00 7E FE 09 D2 19 01 40
The underlined bytes are taken and summed. (in this case the decimal 960). and the bold is the checksum Only the 8LSB (or single least significant byte) is needed to compute the checksum... which in this case, 960 = 03C0 in hex, so only C0 is needed.Two's complement is then taken:
step 1) logical not of C0 which is
step 2) add one (integer)
BIN...........DEC...HEX
[code]....
So here is the code I have been using: (quick mention that in the string passed, the hex bytes are all grouped together, there are no space characters)
Public Sub CreateLine(ByVal Data As String)
'Dim BDataArray(DataLength) As Byte
Dim IDataArray(Data.Length) As Integer
[code]....
where i get into trouble is where i commented 'i get into trouble'. My code works, but it's rather crude Now, in that line i first convert the hex value (string) "SChecksum" into an integer. I want to NOT this, so I get my step 2 from my explanation. However, the results appears to be a signed logical NOT. which gives me the wrong answer. My hashed togther version simply subtracts 256 before the not, in order to give me the correct answer.
Basically, I would love for someone to chime in and point out the flaws in my function, and push me towards figuring out the 'proper' way of doing this. Also I can't quite wrap my head around what would happen in the case a string were passed to my function that is over 16 bits, but I imagine I would have to subtract a larger value than 256, before doing the NOT in this case?(whilst we're on the subject of functions, I've used a 'sub', in which case should I used a sub, and which case should I use a function?).

Detect And Analyse The File Signature Then Compare It With The Extension?
Jun 21, 2010I'm going to do my graduate dissertation this year .My title is develop a forensic tools which is able to detect and analyse the file signature then compare it with the extension.If the extension is wrong match with the file signature then there is a feature in the tools that would revert the wrong file extension to its original state.The problem is there is little information could be found online that shows the code library or function that could enable me to program the above mentioned feature.Could it be implemented on the vb.net or i should do it on C#?Any sample code that could peform the file signature with the extension and also correct the file extension according to the signature in vb?

View 9 RepliesUsing An Embedded Xsd File?
May 18, 2011I am embedding an xsd file into my console program so I can use it to parse XML files into a datatable which I then will parse and process into a text file and into a database. I have embedded the file and can access it by going to My.Resources.LinerTester. This will return a string, but in order to use it on the Dataset.ReadXmlSchema method I have to convert it to an XSD, otherwise I get an error saying invalid characters. How can I take the embedded resource and convert it to an XSD file? I know the XSD file works fine, if I read it from a location on the hard drive it will process the XML files into a dataset just fine, so the file itself is valid.

Embedded Swf File Doesn't Run
May 10, 2012I'm having problems running a swf file from a url.This is my code (Very Basic)
Code:
Public Class Form1
Private Sub AxShockwaveFlash1_load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AxShockwaveFlash1.Enter
Dim swfLocation As String = ("http://pinger.com/textfree/textFree_web.swf")
[code]....
As I said it's very basic at the moment. But I discovered by going to [URL] and look at the source that if I remove the flashvar tag I get the same result as i'm getting in my program. So I thought, hey I need to add flashvars to my script. I first tried it in the property window but that didn't work. The field stayed blank when I clicked away. Then i tried it by using code to set the flash var, still no luck.The goal is to embed this service into a program i'm developing so clients can send and, most importantly, receive text messages with a valid phone number.
Cannot Make Xml File An Embedded Resource
Sep 29, 2011In Visual Studio 2008 I tried to add xml file as embedded resource. During compilation the embedded resource item was simply ignored and the resource I expected to find in resulting dll was not there. I tried several times with no positive effect. Finally I decided to rename the file, so it does not have xml extension. As soon as I changed the extension to (it was .en in this case) Visual Studio started picking the file up and embedding it as part of the assembly. I could not find any any documentation on that odd behavior. Does anyone know if that is expected, and, if so, why ?
