Use MYSQL On Dates Formatted As MM/dd/yy?
Nov 4, 2011
I have a database full of dates that are in the format: MM/dd/yy. For example, today's date (November 4, 2011) is saved in the database as: 11/04/11. I'm having trouble with date ranges since my dates aren't formatted as yyyy/MM/dd (example: 2011/11/04). I don't have a way to change the way the database is populated, so I need to account for the date formatting differences within my MYSQL queries (via VB.NET). Here is my query (it doesn't work well because the dates are in the incorrect format):
SELECT CMP_DATE FROM my_data WHERE OBJ_DATE >= '1994/01/01' AND CMP_DATE <= '2011/11/04'
Is there anyway to reformat the dates within the query?

I'm exporting a datagridview to excel. The first column is a Date (not DateTime) which appears like '2/15/2011'. After exporting the datagridview to excel it appears in excel as '2/15/2011 0:00', furthermore the first 68 rows in excel appear as '6/14/1898 12:00:00 AM'. Where is the time coming from? The column type in the database is date. I've attempted to edit the cell style of the datagridview column to date. I've attempted to figure out how to pre-program the formatting in excel, but it's not working either.

Having problems with null dates in a mysql table. Have eventually found out that I can store a 'null' date in mysql as "0000-00-00" and I can run the 'insert' command to add a record to the mysql table. When I check on mysql workbench I can see the row has been inserted correctly and the date shows as "0000-00-00".However...When I try to load the table into a datagridview, I get an error = mysql Conversion Exception was unhandled = "Unable to convert MySQL date/time value to System.DateTime".

Say the user specifies these two dates....
Start Date: 2010-12-05
End Date: 2011-01-15
If I select December 2010 I should get the folllowing
startdate = 2010-12-05
enddate = 2010-12-31
Select January 2011 then
startdate = 2011-01-01
enddate = 2011-01-15
Should I subtract dates? How can I get the start and enddate for the current month/year based on the overall start and end date.I'm coding in vb.net.

I'm using two datetimepicker controls to set the start and end dates for a range of dates I'm searching for.I want to make sure that the start date selected is not greater than the end date. This code works, but it runs the messagebox prompt twice for some reason. I've tried to ignore it from doing this, but it's not working. Can someone tell me what's wrong?

I have determined thanks to the last q & a that there is something wrong with my "save to db" code as well as my "retrieve to picture" code. Even If I manually save the pic in the db it stil wont retreive. This is code i patched together from 3 or 4 examples around the net.

MySQL databases exists for saving values as strings (text only). Is there any way that i could store files with the same speed as a mysql command ? I know that it depends on the file size but lets say that the file is "Avatar.jpg" 50KB... I ve tried FTP but this is not what im looking for. e.g. You want your users been able to upload a file like the [Add This Attachment] button does in dreamincode.net and you dont have any background on PHP/HTML/Javascript/ASP.NET just VB.NET and the basics of MySQL plus you dont want to use it for a website. How do you accomplish this? Something silly that ive tried was opening an image as text then update the mysql server with that text but it didnt work backwards after i wrote the text on the file and oppened it ...it said that the image was corrupted.

What i have going on, is i have a MySQL connector as a resource on my application, and im basically trying to connect to my MySQL server, to either a) register a new account, or b) check that the account exists and they are premium, and login, Now what i have run into problems with is: My MySQL Database Name has a _ in it which VB is not allowing for some strange reason.
The code i am using is below
Imports MySql.Data.MySqlClient
Public Class Form1
Function UpdateRecord(ByVal query As String) As Integer
[CODE]...
How i can allow the _ into the application, because the only databases that don't have a _ in the user or dbname are a) Paid ones which i DO NOT have the money for or self hosted ones, i cannot leave my computer on 24/7

User posts text into textbox/grid etc Button is pushed. The text is formatted as if it were in a spreadsheet. ie Only x words per row Each cell is of equal length and width.To put it another way; The first letter of the second word of the first row. should be directly above the first letter of the second word of the second row.

I have a wizard I jinned up at work to import a CSV into our database. The intro "welcome screen" has a fair bit of text regarding the catalog format, but it looks so... bland.
My thoughts turned to making an html page, adding it to the project, and then in place of the text box of instructions have a web browser control to load that specific html doc in the project.
The html doc would have all sorts of pretty formatting and what not (bold, bullet points, colors, etc).

my format statement from vb6 is not formating right in vb 2010. Here is what I have.
sw.WriteLine("202" & Trim(Str(1000 - index)) & "0" & Trim(Str(kdex)) & Chr(9) & Format(Plotrecinp(1, kdex),
Chr(9) & Format(Plotrecinp(index, kdex), "#.#####E+##"))
This is what it gives me: 20299901 14415.58E+14415.58E+ It should be more like this: 20299901 2.88462E-1 1.45098E+4 nevermind the difference in the number values. the formatting is what I want.

I've been trawling the web for ages trying to find some dll's/code to be able to extract text from a PDF file and keep the formatting as much as possible.I did find something last year, but it simply took all the text and created one big list of every section in no particular order, so I couldn't read the values I needed from it.

I have a Datetime Picker on a form.
When I use dtArrival.value for instance, it gives me the date in the format "24/04/2010 10:54 PM"
Is there a way that I can grab the value in the format "YY/MM/DD" e.g the value would return "10/04/24"?
Also whats the easiest way to calculate the number of days between two datetime pickers on the same form? I've tried to do it and it's just a mess.

I'm using VB2008 Express and Flash CS4. I'm trying to create a CGI-formatted text file with VB2008 and use it in Flash. Below is an image of the form I'm creating. Beside each number is a textbox for input of the answer follwed by a double-numbered textbox. There's also three radio buttons on the top of the form, "Single", "Double" and "Triple". Single is multiplied by 1 for a number-inputted text box; Double is multiplied by two and Triple is multiplied by 3. Take a look at the form below and you'll see what I'm talking about.

I have run into another problem with my current project. I have a form that I need to print. Doing some searching online I found a few examples and implemented it into my code. It prints but prints all my text boxes and labels stacked on top of one another. How can I get this to print my textboxes and labels formatted as I have them in the form?
Here is my code:
Private Sub PrintToolStripMenuItem1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PrintToolStripMenuItem1.Click
PrintDocument1.PrinterSettings.Copies = 2

I am trying to add formatted text to a rich text box..For instance, I want to add a heading as bold ("HEADING: ") and some data after it as regular ("REGULAR Data")...then a new line and do it all over again.
first name: blah
last nem: blahh
etc...etc...
I'd like to have a couple functions to perform the action.When I use the below functions to add txt to a single rtf box, I get lines in either all bold or all regular. It doesn't seem to keep the font formatting after it adds text..
