Using DateTimePicker For Fast Data Entry?
Jan 5, 2010I formatted my datetimepicker like this "dd/MM/yyyy". I want to move curser once the user enter date then (without enter '/') go to month and then go to year.

DateTimePicker Requires Entry The First Time?
Jun 23, 2010I have a datetimepicker on a form. It is not bound to a table field. When I open the form, I click on the arrow on the right of this control, the calender picker appears, I click on a date, and then I have to hit enter for the picker to close and the date to transfer to the control.After that, I can click on the arrow, click on another date, and the picker closes immediately and the date value goes into the control. Why do I have to hit enter the first time? I would like to be able to transfer the selected date to the screen the first time with just 1 click and without hitting enter.
View 1 RepliesDateTimePicker - Choose Date And Make Entry
Feb 15, 2012I have DateTimePicker where user can choose a date and make entry. I then record this entry into the database. My application date shows 08-02-2012 (i.e., 08 february 2012 in DTPicker value), when I select this and insert it to my database, the MS Access takes this as August, 2 2012, and records it as the same.
I could fix this by using this code:
Dim mydate As DateTime
mydate = Me.dtpicker10.Value.ToShortDateString
Dim output1 As String = Format(mydate, "MM-dd-yyy")
and pass sql insert query using
insert into table (mydate) VALUES (#" & output1 & "#)
Instead of getting the value directly from the dtpicker. This fix the issues, but when I tried to get the date out of the database to filter it between entry made in certain date, I sometimes have problem. How do I generalize this for all type of client computers where the date and time settings can be any form. What will be the best and more flawless ways of approach to target all types of clients? Am I on the right track?
Fast Update Of Bitmap From Polar Coordinate Data?
Sep 7, 2011I am producing a marine radar display in VB.Net and struggling to get the radar data to display quickly enough.The data is coming into my application from a callback from the radar maker's dll. Each dataset consists of an integer between 0 and 8191 denoting the angle from the datum (ship's head) that the dataset represents and a byte array with 480 elements containing data from ship's position (byte 0) to maximum range (byte 480). Each of these locations is a single byte, I want to set both red and green components of the relevant pixel in a 1000 x 1000 bitmap to this byte value. The dataset number increments round from 0 to 8191 as the radar scanner rotates.
My first approach was to use math.sin and math.cos to convert polar coordinates to cartesian coordinates, and then use setPixel to set the colour of the relevant pixels but this is far too slow.I'm now trying to use Boop Boops 'FastPix'
[URL]
Which looks like it should be much better, but I am wondering if there is a more efficient approach, for example cutting out the polar to cartesian conversion, or putting the data direct into a byte array?I am also running the radar picture processing code on a thread separate to the UI thread to keep the UI responsive - what is the best way to display the resultant bitmap onto the UI? I am currently using a delegate and putting the bitmap into a picturebox?
VS 2010 Fast Transfer Byte Data To Picturebox?
Jul 16, 2011I need to transfer a block of pixel values as quickly as possible to a picturebox control. The data will be in a byte array representing 512 pixels by 4 lines. The data is greyscale values from 0 to 255 but I could easily store each value three times to represent R, G and B if that made it easier/quicker to write the values to the picturebox.I've used fastpix (by Vic Joseph "Boops Boops") in the past but this seems more geared towards fast plotting of individual pixels and as I have a pre-formatted block of pixel data I was wondering about alternatives. I've done a bit of research and BitBlt seems interesting, but can this be used with a byte array as the "source"? All the examples I've seen are for transferring/merging between bitmaps/pictureboxes. How about Direct Memory Access? I just need a simple "brute force" method of getting my pre-formatted data into the picturebox. Oh, when I say "fast" I mean I'd like to plot my 512 x 4 pixels in less than 10mS.
View 8 RepliesHow To Create A Simple Report From Data Collected From A Data Entry Form
Oct 13, 2010Currently we are using a VB script macro created in word to create some fairly simple forms based off of data entered on a data entry form. I am very new to VB, and I have been able to create many applications using forms, but I have absolutely no history creating reports. I have been reading up on the reports, and it looks like they are designed to use with data sources like tables. I merely want to take either data from the entry form, or from data derived internaly from processing the user entered data and populate a defined report "form". I have been searching, but there is so much on printing reports, that I feel overwhelmed. I am not looking for the exact answer as much as a link or place to look for a sample for what I want to do.

Listbox Data Extract After Data Entry & Sort
Sep 26, 2011I have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.[code]

View 2 RepliesForms :: Auto-Detect BarCode Scan Entry OR Manual Entry - Cash Register?
Sep 8, 2009i 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.

Communications :: Differentiating Bar Code Entry To Keyboard Entry?
Jul 10, 2009I 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).

View 7 RepliesMaking A Data Entry Form
Apr 28, 2009Im new to this forum and VB Programming. I have installed Visual Basic Express 2008 and SQL Server. The first thing I did was create a new project and within that project created a new sql database. The database I created is to keep a list of clients and I have fields such as client_ID, Firstname..etc The next thing I did was create a data entry form for all the database fields using textboxes. Also 2 buttons named save & cancel. So when the user fills out the client info and clicks on save I want the data to be written to the client table. I know the code has to be written within the save button but I don't know where to start like opening the connection, writing to the database and closing the connection.
View 8 RepliesQuicken Like Data Entry Using Autocomplete

I wish to implement similiar functionsality in a VB program (VS2008). I have some text(description) and a few atributes which are associated with the description.I wish to persist the data and am thinking about using a text or xml to do this.
I really think that a database would be overkill. I am looking at the textbox's auto complete property. The documentation says that the AutocompleteCustomsource is"AutoCompleteStringCollection" and am wondering how to really use this. I had started by thinking that I would
set up a dataset object (its native ability to read/write xml being a plus) but am wondering how to associate the customsource with the appropiate column in the (one) table in the dataset. The other possibility I am thinking is building my own class(probably inheriting from sorted list) that would also expose an AutoCompleteStringCollection.

Related Tables Data Entry Form
Oct 19, 2011I have a Microsoft Access database that has one-to-many relationships. When I created the tables for the database, I did not enter any data into any records, as that will be done by the application user. My problems is when data is entered into the parent and child tables, the parent table data is the only one that gets saved when clicking the save button on the binding navigator.If I have the parent and child tables data entered the same way a user would prior to connecting the data source and add EndEdit() to the child table BindingSource in the BindingNavigator click event, everything works exactly the way I want it to.This application is a data entry form, so it wouldn't make sense to have to have data entered in tables prior to adding the data source to my project. What is the best way to create a data entry form with one-to-many relationships? [code]
