I'm currently creating a text editor (more specifically, a HTML editor). I keep getting the error seen in the picture when I attempt to open a file that I have saved from the program. If I open an HTML file from another text editor, it opens fine.[code]...
View 14 RepliesI have this issue that occurs with me and driving me crazy i have a report that contains thousands of records and i need to export it to excel , but the excel normal extension .xls
is showing missing records at the end of the file , so i save my file as an .xlsx extension it saves correctly but when i open the file it generates an error
"Excel cannot open the file '<var>filename</var>.xlsx' because the file format for the file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file."but when i test the file i drag it and open it in an empty notepad all the records shows up correctly
I created a new cursor (it works properly, I tried it in windows 7) but is not working for me in the program.I took the Windows cursor (aero_helpsel_xl, from C:WindowsCursors) and it appears to me the same error.i use with this code:
Me.Cursor = New Cursor("Patch..")
The problem say:: "{"Image format is not valid. Image file may be corrupted.
Parameter name: stream "}"
edit: I realized what the problem ... It can read only cur files with 24-bit color and lower - but it shows only two colors: black and white.
I have a string coming into my app that is in the form of:
"Fri Sep 21 07:17:46 2008 GMT" or
"Fri Sep []3 07:17:46 2008 GMT" ([] is a space)
The tricky thing is the space for the date. I currently split the string and grab what I need to make a valid VB date.
Code:
'Receiving a timestamp in the format: Tue Jan 23 19:33:31 2001 GMT
'Split it and grab what we need to make a valid vb date
_element = timeStamp.Split
_dateAndTime = CDate(_element(1) & " " & _element(2) & " " & _element(4) & " " & _element(3))
Return _dateAndTime
I'm running into the problem when the date is a single digit because there is never a 0 on single digit dates. So, when I split the string I get a "" for _element(2) and that's bad. I know workarounds to adapt for this, however, my question is: How to implement the String.Format to manipulate this string as is and make it a valid VB date? How to make VB recognize this string as a valid VB date without a prepending 0 on single dates.
I want to to make date format dd/mm/yyyy with access 2003
Dim strdate As string="22/09/2010"
Dim dd1 As New Date
dd1= strdate
I get : Conversion from string "22/09/2010" to type 'Date' is not valid.
Does anyone have a regurlar expression available which only accepts dates in the format dd/mm/yy but also has strict checking to make sure that the date is valid, including leap year support?
I am coding in vb.net and am struggling to work this one out.
with a system of regional date configuration as dd/MM/yy
isdate("13/08/10 10:00") ' returns true, but with a system of regional date configuration as MM/dd/yy
isdate("13/08/10 10:00") ' returns false
how to handle this situation, all i need is i want to check a string for convert able to valid date format & then convert the same.
I wish to add refrence with a dll file.But it fail,it show message 'Make sure dll file is valid assembly or COM component '.I also try use regsvr32 to register it,but also fail.
View 7 RepliesI am getting this error trying to code a connection string between a data set and DataGridView.
I use the Try ... Catch. Upon Catch I MsgBox all the error messages I find to help solve the problem of getting the message "Not a Valid File Name". Without extra help I am blind to what the JET Engine is producing for the path from the path that I give it.
Is there JET Engine attributes that I can access with Visual Basic 2008 at the Catch statement to display what path and file name the JET Engine is producing to get the error? I even get the error with "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:;".

how to flatten an XML file to CSV format. I have worked on this all day today, and although I've found some simple examples, my issue is slighlty different. Please see example below...
[code]...
Notice that the data node has several different structure of child node. Is it possible to write XSL to flatten this?Second question is it possible to write the XSL in a generic way so that it doesn't need to be aware of node names and therefore just works for any XML fed in?
I've been asked to create a string slicing programme that will take data from a spreadsheet and output it to a delimited ASCII file. The data in the text file follows the structure as shown below:
<time:00:00:00:date:01/10/00:lat:52.34:long:28.30:wind:20:temp:-12recipitation:0.03:visibility:50>
The text file has about 7-8 rows off data following the same structure but with a few changes. So I want to remove the semi-colons from each row of data and format the text file so it has the correct columns on the first row and then the data below but with the long, lat removed etc. However I can't just remove all the semi colons as time uses them.[code]...

Or draw a line between each set of entries?
