I use No DirectX, No ActiveX/COM, No Intermediary file, just live video stream.I do however wish to control the ZOOM feature of the camera using the VFW API.(increase and decrease)
View 2 RepliesI would like to be able to control the exposure level on a Microsoft Lifecam Studio webcam. The webcam will be taking pictures of lit LEDs. There is a neutral density filter between the webcam and LED to prevent blooming from the really bright LEDs. There is one person who states he is able to control the features of the camera using the native DLLs:
These DLLs are installed by the Microsoft lifecam desktop software, where you can manually control the exposure, white balance, brightness, etc. I have not been able to get is software to work. When I put in the line. Dim x As New Microsoft.LifeCam.CameraList. I get a Microsoft.LifeCam.CameraList is not defined error message. Are there any ideas how I can control the exposure level of the webcam through my VB program?

View 3 Repliesat work here we use a Remote Machine Viewer called FitNet which is proprietary to NCR and WalMart. However, I had no hand in developing this application and the developers no longer are emplyed here or did they assign anyone to take it over. I was asked to take a look at it and see if I could come up with something. The application is a .NET app but when I use .NET Reflector to get an idea aboutthe code it says no CLI header found.

View 1 RepliesWe've been asked to make a program based on a spec where we enter some details and it will then output a graph.Part of the assignment asks us to set up a timer so that the bar chart will display each bar seperately with a time delay between each one.However the timer is assigned to a form (Form2) while the draw commands are within another class called Expenditure.
While the specification doesn't specifically say we should stop the timer from within the class it is implied.Now I have tried Form2.Timer1.Stop() and Form2.Timer1.Enabled = False within the class without any luck.I'm wondering is it possible for the Expenditure class to stop the timer or does it need to be done within Form2?
I am playing with VB 2008 using .Net 2.0 as the target to compile to and am trying to figure out if it is possible to create multiple countdown timers one in each form using a single timer.I have attemtped but the logic escapes me.

I am working on watermarking image.
In the below code I load the image to the graphics path using resource image and adding text on it. When I add the image through open file dialog it paints on the form with original size but I need to resize it, add it to the PictureBox, add text to it and give zoom and pan options to it and then I need to save with the original size.
When I resize and when save the image I endi up with a small image.

I have VS 2008 and am working in VB.Net forms.I have a webbrowser control where I am trying to control input fields that are dynamically created. If a text field has proper handles such as id and name tags there aren't any problems.
For example, I am trying to work with twitter for posts. I know twitter has an API but I want to work with many similar systems and want to avoid the API as its case specific and I want to scale things within the VB.Net form. The login fields for twitter are easily handled, however the posting field once your logged in is just a text area with a class. There is a tagname but I have been unable to post using the tagname element.Any examples of posting to twitter without the API ?

Dows anyone know how I can build a timeout feature into a windows forms app.
The app is event driven, but I am thinking of somehow using a timer which counts down for say 10minutes, and one the timer ticks then we time out the user.
The problem I have is how can I reset the timer each time the mouse is moved or clicked.

View 1 RepliesHere's the situation: I've got a form that has
- RichTextBox
- OpenButton (to load RTF file)
- SaveButton (to save RTF file after editing)
- Textbox (for search phrase)
- SearchButton
- ExitButton
- 2 RadioButtons (WholeWord and MatchCase search)
All of them are working just the way I want them to except search features; I don't know how to write them properly. At the moment, they search and highlight only the first word they encounter. E.g. say I search for word "the" in the document, only the first "the" it encounters is highlighted. The rest is just untouched.
I understand this is because I've only got few lines of simple code as follows
If rtfText.Find(txtSearch.Text, RichTextBoxFinds.WholeWord) = -1 Then
MessageBox.Show("No results returned. Please try again.", "No matching results.", MessageBoxButtons.OK, MessageBoxIcon.Information)
End If
I did try a few other snippets I found on the Internet including While loop but they didn't work as I wanted them to, and I couldn't understand them either. What I want is, which ever search option is used, when the matching result is found; it will highlight that word and when I click it again it will move onto another word. If I keep clicking, it will highlight the same words (but located in different areas) throughout the whole document and at the end, it will send back to the first matching word. Just like Adobe Reader search.
I am trying to add two features to my webbrowser: View Source and Find. Does anyone know how to get the webpages source code and a method to perform a search in the webpage? I was thinking one might lead to the other.
View 1 RepliesI have a program that is reading an Excel (xlsx) file and I am trying to take the data found in one of the cells and split it based upon the '@' symbol inside that cell. Here's an example: value in cell is "XXX @ YYY" I declare 3 strings (strOriginal, strA, strH) strOriginal is the value from the cell ("XXX @ YYY") then my code is supposed to split up the values in the Original string based upon that '@' symbol.So when my code is done, strA should = 'XXX' and strH should = 'YYY'.
Here is my code
strOriginal = dtbExcelData.Rows(0).Item(0).ToString
y = strOriginal.IndexOf("@")
strA = strOriginal.Substring(0, y - 1)
[code]....
For some unknown reason, the y integer (in this case, it is '4') changes to a random number (it has changed to 44, 61, 124) and causes the error "Error with Excel file: Index and length must refer to a location within the string. Parameter name: length" to occur.I understand why the error occurs (my y integer is not staying at 4)...I just don't understand why that y integer is changing numbers when it should remain as the indexof the '@' symbol. I'm looking for any suggestions on how to pull out the data after the space after the '@' symbol (the 'YYY' portion of 'XXX @ YYY'). Also sometimes the 'YYY' is only 'YY' as well.

I created a Zoom in and Zoom out function for my application and it works great. I would just like your opion on my code, because I am wondering if it can be done a bit neater and more effective.
ts = ToolStrip
cms = ContextMenuStrip
vb.net
If Me.Font.Size < 30 Then
[Code]...
Me.form.font changes the font of all the controls except toolstrips, contextmenu's and menustrips.
Any idea's if this can be done any neater or how you can make menustrip etc.. use the font of the form?
Edit:This is the Zoom In version btw. The Zoom out is identical except it uses - instead of + when declaring the newFontSize.
I have a logitech webcam that I use to take pictures of customers to submit to a server/database. Utilizing AVICAP32.DLL calls, I was able to modify my VB.NET program to take these pictures via a button in my program.
My question is, it would me more convenient to my intended users to click the webcam button, instead of clicking on the button in my program.
Is this possible to do in VB.NET? and how can I do this?
If this is not possible to do with my logitech webcam than is there a Microsoft Webcam that can do this?
