I'm doing an error log in my code and I'm trying to output the errors to a text file with a specific date/time in the title so they can differentiate. I've tried things like
logname = "C:Documents and SettingsSeDingDesktopErrorserrorsLog " & DateTime.Now.ToString() & ".log"
But I get this msg "The given path's format is not supported." all the time.
I am using VB 2008 and want to record a start date and time and then the stop date and time in a rich text box, i can get the start time into the box but so far can only stop the time instead of 2 seperate times, what i have is a drop down box with a list of computers 1-10 i was trying to get it so you picked a certain computer and that went into the text box then you started the timer and that was recorded, finally you stopped the timer and that was recorded but as i am a total newbie it does not work
Here is the code i have.
Public Class Form1
Dim time2 As Date

I'm building an application in which a certain CSV schedule is read and searched for time and date values.
I want to read each cell in the CSV file with a streamreader and have VB determine if the contents of the cell represent a date (like 31-10-2011), a time (like 22:30) or random text data which is not formatted like a date or time.
How can I make VB recognize a string as either a date, a time or neither one, so I can use this string formatted as Date, Time or discard of it?
The contents of the CSV file will look something like this:
;Schedulename;text;text;31-10-2011;text;text;6-11-2011;text;;;text
Although the CSV file will never contain much data, the position of the date and time fields in a row may vary, so I cannot tell VB which cell to read as date/time. It has to recognize the value as date, time, or unusable text.
Dim CSVReadline As New System.IO.StreamReader(schedule.csv")
Cellcheck = CSVReadline.ReadLine()
String = Cellcheck.Split(";")
For i = 0 to 10
Scheduledate = String(i) ............ etc.
The problem that I'm having is that when I try to select a different date, the text doesn't go away. That may make no sence, but let me tell y'all what I've done.
1: Created a GroupBox
2: Put a DateTimePicker in the GroupBox
3: Put TextBoxs in the GroupBox
4: Changed the DateTimePicker to look like this:
A)Checked - False
B)Allow Drop - True
I thought that if I changed that, then the text in the text box would go to that specific date. It didn't do that, it just stays the same. What I'm trying to do is enter text in say 3/7/11 and when I choose date 6/12/12 it will display blank text boxes for me to enter something different.
I am doing my school on project on rs 232. it involoves VB. I have found out how to save text in .txt file in the code. But i have no idea when i save this particular text for instance with time and date oso..

The main form in my application is a small form without a titlebar. I accomplished this by setting these properties:
- ControlBox = False
- MinimizeBox = False
- MaximizeBox = False
- Text = "" (empty)
As long as the Text (title text) remains empty, the form has no title bar. Note that it still has a border so it can be resized (FormBorderStyle = Sizable, as usual, not None!)Now, because I have to keep the Text property empty, the taskbar button never shows any text... But I want to show text in the taskbar button!
As far as I know, the only way to set the text on the taskbar button is using the forms Text property, but I cannot set that because the form will have a titlebar if I do...

I'm trying to include a few text files in my project. These files are read and used to make decisions in the program. Ordinarily, I would just set the file path and open the file via StreamReader, no problem. However, this application now needs to work on other computers and I want to include the text files in the application directory. I've researched two ways to do this:
1) Include the files as resources and reference them via my.resources.
I've gotten this to work ok, except the files are opened as strings upon starting the application. They are fairly large files, which I imagine is taking a lot of unnecessary memory. Also, StreamReader wont work with these files as resources,
or at least I can't figure out how to. My application is already based around using StreamReader so I don't really want to change this.
2) Include the files as additional items. I know how to do this too, but I can't reference the files programmatically.
Can I use a resource text file via StreamReader or how would I reference the files if they're included in my project directory?
I'm trying to set the text and title of the messagebox according a value in an xml-file.Let's say:

I would like to be able to have my users open an Excel file and include their add-ins they have installed and usually show up when Excel normally starts. Using this code, Excel opens with no add-ins visible:
vb.net Dim excel As Microsoft.Office.Interop.Excel.Application
Dim wb As Microsoft.Office.Interop.Excel.Workbook
Try excel = New Microsoft.Office.Interop.Excel.Application
wb = excel.Workbooks.Open(filelocation & "checks.xls")
excel.Visible = True
[Code]...
Is there a property to allow add-ins when opening an Excel file?
I have a favorites bar in my web browser and when I display them on a toolstrip as a toolstripbutton but the bookmarks are stored as a string collection in my.settings and It only displays the url of the bookmark (not the document title of the site)Is there a way to have a toolstripbutton that has the text of the Document Title of the url and the url as the tag of the toolstrip button?

I'm updating an old VB net application and trying to refactor some of the logic as I go. The app looks for data from a single date across a few tables and writes that view to a file.
Writing the query in SQL I'd get the equivalent of
SELECT * FROM table
WHERE CAST(FLOOR(CAST(table.date AS float))AS datetime) = '15-Jul-2010'
Ideally I'd use
SELECT * FROM table WHERE date=@input
and add a date object as a parameter to a System.Data.SqlClient.SqlCommand instance
Are those two comparable? Will I get the results I expect?
I am new to VB and Visual Studio. Using VB 2010 express edition. I am making a VB project and from from inside that i want to be able to run a batch file that i already have.
My problem is i am not able to import this in my project. I tried adding it in the project from solution explorer but when i run the program its not able to find it. I am able to execute it when i copy that batch file somewhere on disk and then giving absolute path but not by including it inside my project.
I'm using IO.File.ReadAllLines(FileName) to read all lines from text file to array of strings at once. Problem is, text lines include ANSI characters above ASCII value 127 (Scandinavian letters e.g. "Ä" (Ascii 196), "ö" (Ascii 246) and "é" (Ascii 233). Array is build up nicely, but all chars above ascii value 127 are not shown right. How can I use ANSI character set with .ReadAllLines to correct this problem? In VB6 with "Open Filename For Input As #1 / Line Input #1, txtLine" there wasn't any problem.
View 1 RepliesWhen I publish my program I get no errors, and then when I install it on another machine it says it gives me the error that it can't read the txt file that it stores data in. If I hit continue it also fails to read the database. The database file is stored in the bin/debug folder and I told my program to include it when I first added the data connection. Anything I can do to have these included so my program can run on other machines?

I'm try to come up with a way for a user to enter a date and time into a textbox and for that value to be saved as a datetime variable back into a database. I'm wondering if anyone knows of a clever way to restrict what values a the user can enter so that the datetime datatype isn't corrupted. I've been playing around with the date time picker but I cannot seem to get that to work for me. I'd like the user to either pick the date and time from a picker and save that into a variable. Or I've seen applications where the textbox will automatically have a formatting type of template that makes it hard for the user to enter an invalid date and time.
View 2 RepliesI have created a text box....a button and a date time picker control. I have showed the calander control on click of the button event....when a value is selected in the datetimepicker the value should be showed in the text box...I have done this....in the datetimepicker value change event
But then I want that the datetimepicker control to hide again...but this code I cant write in the value change event since if I write the hide code in datetimepicker value change event it will hide it every time...cant write in lost focus also since it will have to wait till the focus is lost. cant write the code in text box value change event since the value will be changed after every click in datetimepicker I want to write the code when the value in calander is doubleclicked...
i load a text file that has the data of the textboxes that i already saved to see the title of the text in a label.
