I have an application which has a label, set to multiline. This area of the app is for notes and comments. One of the database tables behind the app is specifically for thenotes/comments table.I want to set it so that when someone puts in a new entry, the date is auto-inserted so we can see when they did it.
First i populate the data i wan in a listview than i click on a button to export all the data in the listview into a notepad call default.txt but upon clicking the button i realise that there no data inside my notepad
I want to create a notes app for Windows Phone 7 using Visual Basic.I have read a few tutorials but they are all suited for C# not VB. Basically, I have a main page and a page to add notes. Once the user types out a note on the add notes page, the title of that note appears on the main page. I also want the user to be able to select that title and it will display the note. I have done a bit of research and I know I will need to use isolated storage (not sure how to implement it in VB) to save the notes. I think I will also need a list box that will store the title of the notes.
Type 'datestamp' is not defined...How can I update it to resolve the error..
Dim blank As New DateTime(1900, 1, 1, 0, 0, 0) For row As Integer = 0 To dgvReturns.Rows.Count - 1 Dim value As Object = DgvReturns.Rows(row).Cells(9).Value
i am pulling together a cash register that will allow both bar code product entry and manual key entry.imagine if you have a tin of beans in front of you, in a small corner shop they would probably type "47" and then hit "Produce". Fairly straight forward as I have the button Produce to act upon my code and update my salestrans.mdb but,if you scan the bar code I want the same form to handle both 'real' actions, (i assume that keyboard emulation barcode scanner includes "ENTER" after providing 13 digits)....
Q. in perhaps a long winded way i want to know how to kick off an event based on the "ENTER" key being activiated by the barcode scanner)?i do not want to have to hit any buttons if i am scanning bar codes.
What is the code for ignoring the case of an entry while checking to see if the entry is correct or not... (i.e. in a flashcard program... given definition, asks for the name) I don't want the case of a character to affect whether the answer is correct or not.
I am trying to make a program with a bar code reader for the first time. I am programming with VB 2005. I want to differentiate a bar code entry to keyboard entry. My questions:
1. Does bar code reader generate a keydown (or keypress) event for each of the digits of the entry? For example, if the barcode read: 1234567890, does that mean that there will be 10 keydown (or keypress) events for that single barcode that was read?
2. I have read from the posts that the best way to differentiating keyboard vs bar code input is to analyse the time between keystroke (for less than certain number of milliseconds).

I've written an VB application and have successfuly got it into the form of a web page using Visual Web Developer (VWD).The application has a link which opens up another web page in a new window. I would like it that code triggered by a Button on this application will only run if the web page has been opened via this link. In VB it was easy as clicking a Button object made code run (which opened up the WebBrowser within the application) and I could therefore include a line of code such as eg. trigger=1 (and then later I could use "if trigger=1 then"). But in VWD Toolbox objects "Link" and "Button Link" take you directly to the web page (ie they are hyperlinks), without giving me the opportunity to include my "trigger=1" line.
I used vb2008 and make a good application and make setup file by advanced installer builder .And install and use one month then I formatted my pc .Then install my application without install vb2008but I get a warning message as
I have three Tables in the MS Access database as below:
Company_Data Name|Age|Department|Salary User_Data
[Code].....
and i have a compare button on the VB form. Is there any code that can compare the Company_Data with User_Data and copy all the records not found in User_Data to Changes_Data table. When updating it should update the "updated on" Column to the current Date.
Same needs to be done in the opposite way. Compare User_Data with Company_Data and note the diff. No Need to update Salary in this case.
currently i have created a note pad which contain names
For Example : ( inside the note pad ) Sam1
Candy1 John1
But it not showing up in my listview1 box , it seem to go straight into the Error Msg ( File not found )

Dear Moderator Sorry for posting it here. Could not find a proper place for posting Query related post and also it was urgent. I have a database in MSAccess.I have a table as tbl_Menu.This table has a parent child relation ship.Parent Node is : MenuItemId and its Child Node is : MenuItemPopUpHeaderID
Alright I am trying to make my checkbox have like a little discription on what the check box means when the users mouse is hovering over it. How would I do this?
I am rather new to VB and every now and then I get an idea of a small project I would like to work on to increase my skills. What I am trying to do is: 1. Input the sound from the microphone 2. Detect what pitch the sound is 3. Compare it to the pitch displayed
For example, lets say I was to have the button "Start". When start is clicked, a pre determined (Or possibly random) note is displayed through a Label for 5 seconds (Lets use C as an example). During this time, the user can attempt to match the note C. When the user sings through the microphone VB picks it up, detects what note the user is singing at, and then scores him over the 5 seconds based on the difference between his note and C. It would also be nice if I could display the volume of the microphone, but this is not too important.
I'm pretty new to VB and I chose a project for school to recognise the pitch/note of a sound comming from my microphone (Which I'm using singular notes using my Guitar). I have no idea if this is even possible :/ So if possible, what things should I be considering and what I pretty much need to do to get the ball rolling for me
What i need it when you select a row, it will add the Note to the richbox. For example when i select that row, it will add "this is just a test " to the richbox. How would i do this ?
I want to make a program that detects the note that is being played in front of the microphone. I am testing the FFT function of Naudio, but with the tests that I did in audacity it seems that FFT does not detect the pitch correctly. I played an C5, but the highest pick was at E7.I changed the first dropdown box in the frequency analysis window to "enchanced autocorrelation" and after that the highest pick was at C5.
In VB.NET 2005. i am trying to experiment with sound. I started out trying to produce a single note at a single left-right position, for a particular duration (maybe until i shut it off. with a particular frequency.It can be a sine wave, or a square wave or maybe a general midi sound. This seems to me to be a simple task, but i cannot find out how to do this.I suspect that the answer lies inside direct sound or xaudio2. I want a simple solution i don't want to have to spend 1600 hours learning xaudio2 in order to learn how to how to make a beep.The ideal answer wold be for me to write a routine that accepts waveshape,freq,volume,Stereo_Position,duration).
There is this software called Harping midi. You can view it here [URL] I would very much like to recreate this software but extend on it. For example. I would like to be able to pick up the "midi notes" and then translate that to guitar tabs. I would like it to have the same features (channel filters, tempo control) those sort of things. Where would I start???
i'm working with crystal report and i use (if not ispostback) to set X and in else to retrieve X . the problem is its working properly in some pages and not working in others.this code sample.
If Not Page.IsPostBack Then Session("VehicleStatusSelectionFormula") = SelectionFormula Else[code]....
the problem like i said in last note with ("EnableViewStateMac="false") it make ispostback true all the time.
