VS 2008 - Append Now Time Part To Date Variable

Jan 11, 2010

I'm working on a small accounting app. I have a query to show transactions with a running balance.

SELECT transactionid, transactiondatetime,
amount,
(SELECT SUM(amount)
FROM dbo.transactions as D1
WHERE D1.transactiondatetime <= D0.transactiondatetime) AS balance
FROM dbo.transactions AS D0

I capture a gamesheet for a certain week. so if I select a date on a monthcalendar the sheet applies to the weeknumber of the selected date. When I save transactions I take the date at the last day of that week as the transactiondate. I need to store a datetime though because my query works of the datetime to get an accurate running balance. How can I append now() time part to my date variable and then store that in a datetime variable to get a transactiondatetime.

Here is my code for getting a transactiondate:
Dim dt As New Date
dt = Me.MonthCalendar1.SelectionStart
'get last date of week. Friday
Dim tdate As Date = dt.AddDays(5 - CInt(dt.DayOfWeek))

VS 2008 - Quick Webbrowser - Get Value Part From Source And Have It Printed Out To A TextBox On Program

Mar 13, 2010

I am using a Webbrowser in my program.

In the page source of a certain URL is the following: <input type="text" name="email" maxlength="50" value="email@email.com">

I'm trying to get the value part from the source and have it printed out to a TextBox on my program. I'm not sure how to do this but I tried. I made a new HtmlElement called email. Then I did email = WebBrowser1.Document.All.Item("email") However, when I try to add it to my textbox it doesn't work.

Variable As Part Of A Control Name?

Mar 31, 2010

Is it possible to use a variable as part of a control name kinda like you would use a variable in a SQL statement. For example:

Lets say we have 4 text boxes txtP1Val, txtP2Val, txtP3Val and txtP4Val. Is it possible to have the P1 - 4 as a variable so it would be "txt + Some string variable + Val"

Forms :: Using Variable As Part Of Control Name

Jul 25, 2009

Basically, I have a large number of text boxes. Within these text boxes, I'll be doing calculations based on user input and other things. These boxes will be grouped by numbers, eg Cost1, Profit1, Stock1... Cost26, Profit26, Stock26. Without too much explanation, I went to write a FOR loop to perform a repetitive calculation across multiple groups, and the following line came up.

FOR num = 1 TO 26
Cost(num).text = ItemCost

What I've tried to do is use a variable to decide which 'Cost' textbox, from the available 26, to use in the calculation. For whatever reason, it won't work. I would like to be able to use a variable to specify exactly which textboxes I want used, so that on the 3rd pass of the loop, the 3rd box is used, and on the 19th pass, the 19th box is used. Otherwise, I'd just have to do each calculation separately, and write the same thing 26 times, with slightly different numbers.

VS 2008 Get Information From Textbox And Assign It To A Variable?

Feb 28, 2011

am explaining this stupidly, but I'm still very much a VB newbie. This is a question about uni work, but it's not an assignment/test, just a little optional extension task.I have three text boxes, the first one is where the person's name is entered and the next two are where you enter the (same) person's score for two tests they have completed.

VS 2010 Read Specific Part From File Into Textbox?

Mar 12, 2012

I want to make an option to load a playlist file into a textbox.. To do this i guess i will need the OpenFileDialog and Streamreader..

Untill further i have done this

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
OpenFileDialog1.Filter = "Playlist files|*.pls;*.asx"

[Code]....

I want to be able to read ONLY the link from the file.. In the first file above it would be after the "File1=" text in the file.. And in the other file it should be whats written after the "<ref href="" part..

And as you see in the second file there are three links, so to start with it should only read the first line, maybe later i could make a selection window popup or something..

Multi Form / Part Application Need To Make Part Protable For Transfer

Feb 22, 2011

im making an application in vb.net (duh!) anyway i have created and coded the whole project and it performs exactly as i want it to (i dont need code help). my problem lies with the fact that my project is 2-3 parts

1.a setup form that gathers inital data about the enviroment stores this data encrypted in a config file. after inital setup this form is not displayed again. but needs to be run on both computers

2. the second form is the real application form im in the process of turning this part in to a background service anyway this form is the one that establishes the connection between two nodes it works correctly

3. the config files

anyway here is my problem i want to make this application distributional with just one file the (.exe) and have this .exe make everything else happen. it runs the setup form and creates the first config file which it does then it needs to produce a copy of just the second form and the config file to transfer to workstation #2 that will run independtly without the whole application which i cant make happen then it needs to turn both workstations application on by only starting one on either computer and invoke the other computer to start its corrosponding app also no idea how to make this happen any ideas or suggestions as to where to look to try to find my answers.im thinking i might need to make two seperate applications (a setup app, and the running app) and include them both in a project and use the setup.exe to to package them together this is a little side project that im making for my self to use to make programming a little easier so i plan on giving it out to some fellow students to test and tell me what they think so im not really worried about ease of use or complicated procedures yet but if it turns out to work and actually be of use to anyone else i would be willing to rewrite it to distribute to the masses but for now i just want it to work for me.

VB 2008: What's The Counter Part Of Drawline

Apr 8, 2012

how to remove a line?I have:

Dim PenColor As New Pen(Color.Black) and after I received the values I draw the line with:
objGraphics.DrawLine(PenColor, Xstart, Ystart, Xend, Yend)

The user can do this 10 times... (so 10 lines)...But if the user presses a cancel button, the last line drawn shall be removed (and the user can click until he is back at 0)..Would I use PenColor white here (to draw over the line)? Or is there a way to remove line directly in visual basic? I couldn't find it.

VS 2008 : Search For Part Of An Image?

May 14, 2012

I want to be able to:

1) save the screen as an image

2) use this image and search for a smaller image inside of it (pixel sequence)

Basically, I need the program to detect when an image comes onto the screen.NOT a pixel color at a certain coordinate, it is similar to this but instead of one pixel, it should detect multiple ones.is there any way I can put the image I want to detect in a picturebox, and it will go look at that image and keep checking to see if it exists on the screen?I have it working for pixel detection (only 1 pixel), but it isn't very reliable as there could be many other instances of this color on the screen.

VS 2008 Deserializing Part Of A Class

Mar 23, 2010

I'm saving potentially very large amounts of data to disk as a single serialized class. But there is a sub class that I would like to be able to retrieve and write back to the disk without having to read the entire file or write back the entire file. Trust me, my reasons for doing this are good, and the design behind this is more than correct.In VB6 this is very easily done. A single statement gets the portion of the data you want from the front of the file and saves it straight to the Type it belongs to, flawlessly. Likewise, if the dimensions of the data haven't changed, but only the values, then Put can be used to save it right back to the file without disturbing the integrity of the entire file.When needed, the entire file is read into a larger structure, and the entire file is put back, but only when necessary. Most of the time the only information being read from and written to the file are in the first few hundred kilobytes of the file.

Now that I've got serialization working, I'm trying to use it to read (deserialize) only the first member of the class serialized to disk. I haven't been able to find any examples of this anywhere that have lead me toward making the sort of progress I'm hoping for.So I suppose the first question is this: Is it possible to read only part of a serialized class from the open file stream? Specifically, in one case I want to read the first two integers stored in the class. In another case I want to read only the first block (sub class) from the open file stream. In both cases I do not want to read the entire file, but just what I'm interested in starting from block 0. I don't need to write back the integers to the first file, but I do need to write back the block to the second.Assuming that the answer to the above is yes. My second question would then be: How is this done? I want to work with the file stream already open rather than opening and closing file streams over and over.I
