Write A Program That Will Capture A Twain Scan?

May 17, 2011

I need to write a program that will capture a twain scan, then let the user input a file name and append a date and time stamp to the file. Afterwards, it should upload the file to a ftp share on our network. As a bonus, I would like it to log the transaction to a SQL server so we can verify the file was uploaded. The catch is, I have almost no programming experience. I have written a small program here and there, but never something that I had to call an outside source for besides SQL. We do have an in-house VB programmer, but he is to busy to do something like this. I wanted to give it a try myself before hiring someone else to do it since it sounds like such a simple program. I know how to layout the basic forms and I can probably figure out how to log the transaction, but I am looking for examples on twain scans and saving to ftp.

Pan & Scan Effect In VB 2008 Video Player Program?

Sep 1, 2010

I've made a video player, that can play almost all popular video formats. But the problem is that I want to add a pan & scan effect to the end user, also if possible a overscan effect also. I'm using MSVidCtl to view and then MSVidFilePlaybackDevice to play and control the file, I've searched the net a lot but found nothing helpful especially in VB.NET, I can use managed DirectX directxaudiovideoplayback.video but the same problem exists, can't find a way to add these pan & scan, zoom in and overscan effects.

Sep 14, 2011

The purpose of the code below is to scan a program of mine to detect a pixel color change. It loops through until a change is detected. It works fine for about 10-15 seconds and then I get an ArgumentException was unhandled error. So far this has happened on two different lines at separate times...

Scanning From Twain Driver?

Jan 28, 2011

So - we are FED UP with our medical records packaging (document imaging) system and want to create a simple filing interface for our scanners to use in VB. Part of this deal is getting VB to interact with a TWAIN Driver.

There is some code out there for ASP.NET and C# - does anyone know of a VB.Net based code I could look at?

I have spent part of my day trying to recreate the ASP into VB but the calls are just different enough to get interesting.

Scanning With TWAIN - Hide The UI

Feb 18, 2010

I am making an application to scan with TWAIN. I can get to state 4 OK, and scan with the UI. But I need to hide the UI. When I do this the scanner does nothing. I believe it needs some capabilities set (like height and width). So I try to get the physical height and width so I can set them. Herein lies the problem. I get 18874402 back for the physical height and width. (neither can I get the units). I get RC=SUCCESS. I don't think it could be a signed/unsigned issue because what boundary is at 18 million +/- with whatever units? I tried some other code I found but that returns 0. I can't figure out what I am doing wrong. Here's the code:

Cannot Set Capabilities Of Scanner Through Twain Driver

Sep 9, 2011

I have been working with TWAIN driver for few days. I have learnt how to connect to the scanner or get the working scanners connected to the machine. I am having a problem now, eventhough i get connected to the scanner, I am not able to set the capabilities from my application. The scanner scans using the capabilities that are set on it but not from my application. I have looked at the sample code given with twain pro but even that doesnt set the capabilities of the scanner. For example if the scanner is set to 300 dpi and I set 200dpi from my application, the scanner scans with 300 dpi. It gives me an error saying that the value given is out of range.

Perform Twain Scanning Using The Twain_32.dll?

May 2, 2012

I am trying to perform Twain scanning using the twain_32.dll, but no luck. Whatever solutions I have got call the dll GUI.

I want to perform scanning by passing custom settings to the scanner for every scan. For eg. In duplex I want to scan the Front side in color & Back side in Grayscale. OR Scan every Alternate page as Color and B/W

The combination can be anything. I've tried & and succeeded using WIA but it limited me to a certain extent. how to proceed using TWAIN and without displaying the GUI. I am open to options where a communication to Twain Connection Manager is established & commands are passed.

Webcam Capture Program - Object Tracking

May 7, 2012

I am making a webcam capture program in vb.net to scan qr codes. I found some examples that show tracking a certain color, but that wont work because the qr codes have different colors. some are red, blue, purple, black, and green. I am using the touchless sdk to capture the video. How would I go about tracking the person's hand holding a 1"x1" cube? I am trying to reduce the "background noise" that the scanner has to try to read through.

Write A Program For VB Class That Consists Of A Resistance Checker Program?

Sep 20, 2010

i have to write a program for my VB class that consists of a resistance checker program. I've searched like a madman to help me through this and I have found nothing >. The program consists of 2 combo boxes, the first one is the nominal resistance drop down list of the numbers :100, 150, 220, 330, 470, 680, 820 and 1000. The second list is of the tolerance numbers; +/- 0.4%, +/-0.6% and +/-0.8%. Now what i want to do is select a number from the first combo box and select the tolerance level of the second combo box and i input the resistor of said value into the text box. when i click the check resistor button it should display a message saying if the resistor is in or out of tolerance. For now I have the form all laid out and the values inputted into both combo boxes and i can go to run the program i am able to select said values. Now my problem is trying to get the right code so that i can check the resistors value.

Error In Serial Port Data Capture Program In Visual Studios 2010?

Apr 11, 2012

I'm trying to make a rs232 serial data logging program, that accepts a 12 bit hex RFID tagID from an RFID module. My end objective is to save this RFID tagID into a database and assigned to a person for a personnel management system.I had to use button3 to add the value of the variable 'msg' into textbox1 because I was getting the following error "Cross-thread operation not valid: Control 'TextBox1' accessed from a thread other than the thread it was created on". It is a temporary workaround.When I do press button3, I get the incomplete hex number, instead of "4C00A2C82A0C", I get "A2C82A0C", and sometimes I get random digits like 1,A,C etc etc.
