I have a graduation project. I need to get the data form the blood pressure meter which has a usb gateway. this device also includes software that enables user to archieve the result in html or txt format. What I need to do is trasferring measured result from BP meter to PDA instead of PC. I think that if I reach the dll code of the application I can find a solution to do it. ıf you have better I idea I am completely open mind.

Rather than disassembling existing executable code you should try this list:
1. read the documentation, especially the "programmers guide" for your BP meter;
2. study the source code of any PC application that the manufacturer may have provided;
3. check the manufacturer's web site;
4. contact the manufacturer if any of the above isn't available;
5. google your problem.

Disassembling the code in that .DLL is not going to help you at all. MSCDRUN is the runtime library for Microsoft's Connection Designer. It doesn't have anything in it that describes how the connection itself is made or how data is transferred.
Like Luc said, your best bet is to start with the manufacturer of the device and see if they have an SDK for it.

thanks for your attention. some of my collegues suggested me to make reverse engineering using dll files of the software but as you mention before I could analyze some of dll but they do not imply anything to me. I will follow your suggested way.

1) maybe you can P/Invoke the metodhs in the dll, use the Depedency walker to se what methods there is in the dll, use google to learn about those methods and implement them in your .net application.
2) Use a disassembly for unmanaged code, and recreate the logic in the resoulting asm code in .net
3) Use a c++ decompiler, and recreate the logic in .net, all c++ decompilers, but rememer they produces really bad output.

hi, i'm creating code only Custom Activity inside app_code folder in asp.net project, but i can not use my custom activity from the toolbox.
I tried separate my custom activity into new class library project and add reference it from the site and it works (available in the toolbox).
question is:
is there a way to use my custom activity from the toolbox without separating the project? (using .cs within site's app_code folder)
thanks for any help
regards

I don't think you can do that. Visual Studio requires that you register the component with it as a dll so that it can find it all the time.

Hello, This is Vikash Gohil
Here's my Query.
I have a Device which is a Linux based device. It works on Linux OS.
I can use telnet from windows on that device and LogIn into it.
I tell you the procedure.
1) I telnet the device using it's IP Address in Command Prompt(WinXP)
2) The Command Prompt then displays me some lines and Username: Prompt to enter Username
3) After Entering Username it asks for Password, After entering password I press enter.
4) On pressing enter, the system Logs me into the Linux OS on the Device.
5) Here I can run Linux Commands to do my operations.
6) I use VI editor to open, read/write certain files that are present on the Device.
7) And then on entering Quit, I am again returned to Command Prompt in Windows.
Now the query is Can I make my Own application in VB.net to perform the above tasks?
If Yes, then give me some ideas on that.
If No, then Is there any other way I can do this.
Thanks in Advance

I want to display a popupcontrol .The intial size of popup will be 0,0 and i need it to bring to 200,200.how can i use timers for that.The popupsize must increase accordingly.pls help me
|
|
|
|
|
Simple, Just use loop (i.e. For loop) to increase size
exa:
For i As Integer = 0 To 200
control.Size = New Size(i, i)
Next 
|
|
|
|
|
Bad idea considering the form wil not redraw until the loop is finished.
|
|
|
|
|
thks for ur reply,i want to show the preview of an image on mouse hover and it must not come at a once but as slowly increasing its size ,can i get it ..pls help me
|

Put a Timer on your popup form, set it's Interval to whatever you want. Handle its Tick event and change the Size propetry of the form in smallish increments. When it reaches your desired size, Stop the Timer.

i used tried like tis
Private Sub PictureEdit1_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles PictureEdit1.MouseHover
Dim PicPath As System.Drawing.Image = PictureEdit1.Image
PictureEdit2.Image = PicPath
PopupContainerControl1.SetBounds(Control.MousePosition.X, Control.MousePosition.Y, 0, 0)
Timer1.Start()
Timer1.Interval = 3000
End Sub
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim i As Integer
For i = 0 To 200
If Not i = 200 Then
PopupContainerControl1.Size = New Size(i, i)
PopupContainerControl1.Show()
Else
Timer1.Stop()
End If
Next
End Sub
But popup was shown at the end and not from the intial size so it didnt looked animated...i am not familiar with timers pls help me

i also tried tis
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim i As Integer
If Not i = 200 Then
PopupContainerControl1.Size = New Size(i, i)
PopupContainerControl1.Show()
Else
Timer1.Stop()
End If
i += i
End Sub

Both code snippets are wrong. The first one you posted would take 3000 milliseconds (3 seconds) per iteration of that loop you put in, which you don't even need!. So, doing the math, that would be about 10 MINUTES to resize the window.
This second code snippet will never reach 200 because you keep re-declaring i, reverting back to 0 every time you enter this loop. It never really tracks what the current size of the window is and add to it.
First, change the Timer interval to something like 100 milliseconds, then, in your Timer tick, add about 40 to both the width and height of the control. That will resize the window in 5 steps in 500 milliseconds (half of a second).
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
With PopupContainerControl1
Dim newSize As New Size(.Size.Width + 40, .Size.Height + 40)
.Size = newSize
If newSize.Width = 200 Then
Timer1.Stop()
End If
End Width
End Sub

for the understanding i developed a simple webservice with add function.when i get the result it should be a message of SOAP format but i get only the result.
the tags like soap-env, body are not there , is there any way to retrieve the complete message.

Hi,
anyone can help for text file spliting ? issue is the text file is big in size and we need to remove first few lines for before we start spliting the file since it contains some header information such as date , time , file name etc say about 6-7 lines. so its creating problem otherwise all data with header line is in tab delimated format or any way we can skip those file using any script or remove them from the text file and create new text without header info.
with regards

hi guy,
1.) create a new textfile with System.IO.TextWriter stream.
2.) read your textfile with a System.IO.TextReader -> ReadLine() till you skipped your headerfile at i.e. line 6-7 in a loop while ((line = textReader.ReadLine()) != null) (count up to the line you want or check till your expected line reached...
3.) after you skipped the lines you want to, write all the following read lines to the textwriter stream -> textWriter.WriteLine(line)
4.) done reading the needed information close the textreader and textwriter -> .Close()...
5.) Finished
sooo far good luck

Thanks , but the thing is file size is around 30 GB , so reading is slow and i want to split the file over a line no how can it be possible.

What are you doing with the file? If you're loading data into SQL Server with bcp, it can skip lines "[-F firstrow]"
|
|
|
|
|
could you please provide step on how to load in sql using -F first row , i tried but since the first few rows are not as header i mean they don't have tab seperated values they are just simple text where as the other lines in text file is tab seperated.
|
|
|
|
|
As I recall, it just tells bcp to skip some number of rows. Read the documentation and try it.
