Read Csv File Into Dgv And Preserve Leading Zeroes.
Oct 7, 2010
I am writing out a CSV file in a VB.NET Windows Application. It is a string, like this:99,Company,00666,TBDOn another form, the user can browse to this file and open it.When he does, I use the Microsoft Jet OleDB provider and read this file into a datagridview. It displays the four columns in the grid, but it truncates the two leading zeroes on 00666 and displays 666.I need those leading zeroes. I tried writing out the string like this:99,Company,'00666,TBD(notice the leading single quote before 00666, like you would type in an Excel cell to indicate it was text), but then when the four columns are displayed in the grid, I have the single quote and the two leading zeroes. I don't want the single quote, I just thought I could use it to indicate text.So my question is how can I write out a string of leading zeroes and have them read into the grid preserved?
I'm trying to have a Textfield lose it's leading zeroes when the user leaves the field. I made the following "Leave" event but it's not working. It works for the first half however to set it back to 1 if it's blank or if a user entered 0. I tried following the advice on this answer, but it didn't work:
Converting an object .tostring() removes the leading zeros. The object is not a fixed length, so I can't do object.tostring("0000000") where the number of zeros represents the fixed length.
An example object value is "0357" when I convert that object .tostring it becomes "357".
Is there a method for keeping the leading zeros where the length is not known?
I have a txt file that I need to read into a listview, but I need to read from a specific line in that file. Below is a sample of the txt file to read,
I have tried just about every format I have found, and I can not seem to get the string digits 0-9 to show up as "00 - 09". Now I do not want numbers 10+ to show up as 010, 011, etc. I also know there are (2) ways to format strings as well:Microsoft.VisualBasic.FormatandString.FormatI have tried all of the following with no[code]...
I have got my timer ticking but I need to add the leading zero back in but it code I am using only works on the seconds (label3) not on the minutes (label4)! Timer Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick Label3.Text -= 1 If Label3.Text = "00" Then Label4.Text -= 1 [Code] .....
I have a masked textbox formatted as "##:##:##:##". When I send the variables to it if the number is <10 I don't get the leading zero displayed. For example:[code[What I want it to look like is 00:01:02:03, what I get is 00:12:3. I've tried the variables as an integer and a string with no luck.
i was wondering if there was something i can use in VB which will let me have some fields in the DGV query to automatically have the format of 0.0000? There are some fields in that query which require this format. The Crystal Reports that accesses it gives incorrect info without this format type.
I am trying to format a date from a table that I'm getting so that I can concatenate it with another string.But I want the leading zero - I don't want 1/1/2009 - I want 01/01/2009.
I can't seem to find a formatting pattern that does this.
I need to format an entire column via Visual basic .net for VBA excel spreadsheets. I need to format the column to the following custom size ("00000").
I am using the following to select the range: ws.Range("AC:AD").Select()
I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.
format a decimal value to a string with a single digit after the comma/dot and leading spaces for values less than 100?For example, a decimal value of 12.3456 should be output as " 12.3" with single leading space. 10.011 would be " 10.0". 123.123 is "123.1" I'm looking for a solution, that works with standard/custom string formatting, i.e.
decimal value = 12.345456; Console.Write("{0:magic}", value); // 'magic' would be a fancy pattern.
When populating the data into a date masked text box for display, I am not getting the zeros in front of the month and day resulting in the date 07/02/1974 displaying as 72/19/74.
How do I insure the month and day have the correct format before the masked tb gets filled. The data type in SQL is small date and displays in the table as 1974-07-02 vS2008 / SQL2008
I'm unable to get rid of the leading zeros in my time format. I want it to say 2:30 (two minutes 30 seconds) not like this 00:02:30. Is there a way to do this? DateTineInput1 and DateTimeInput2 are both text boxes. Here's all the code for the time format and duration
Private Sub lstTracks_SelectedIndexChanged(ByVal sender As
VB 2010 SQL Server Express 2008 R2..When I try to insert a new row in my data table, the account_no field, PK, nvarchar(9), leading zeros are trimmed.String variable "000000010" is saved as "10".If I use SQL management to INSERT the row, then it is save correctly.[code]
I have a number of word documents I am converting. Everything is going great until I get a file that is read only. In this case I get a Save As prompt.
Is there any way to open the file in read/write format? I should have admin privileges so access isn't an issue.
I'm using VB.net to open the files. More specifically
I want to generate random number, which is 9 digits including leading zero if the number is less than 9 digits, say 123 will be 000000123. I have the following code which doesn't include leading zero : Dim RandomClass As New Random() Dim RandomNumber = RandomClass.Next(1, 999999999)
I have a textbox on a form that I use just for output (read only). After doing some calculations I display the value in HEX string as feedback to the user like:
txtReg0.text=HEX(Reg0) 'Reg0 is a UInteger previously calculated
This seems to work fine except the textbox only shows all the HEX characters if the first character isn't a zero. Otherwise, it shows less depending on how many zeros are leading.I WANT to show all (eight in this case) the characters regardless.
This should be fairly basic, but say I have a Public property as local variable on my WCF service, and I set this in one call to the service. Is there a way to preserve that data for another call to the service? (Without writing the data to xml or a db, and re-referencing it or anything like that)
Executing the calls from the Winform:
Public Class ClientSideWinForm Private proxy As ServiceReference.Client Private Sub Client_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Basically I drew something on a form using Graphics. Now if I move a window over the form the stuff I drew gets erased.Is there a way to preserve the drawing?
I am working on a richtextbox application.When I typed text into it and hit return, the returns were preserved.However, when I opened the page up in my Microsoft Vista notepad.exe program,the returns were not preserved.The text appears as if wordwrap was unselected in my notepad.exe program.I just got one long strings and no returns.How can I fix this problem so that the returns are preserved? when I open the file back up in my richtextbox program, it appears as I had typed it with all the spacing and returns.
