Any single part of the path, a directory name or filename, can be up to 255(+/-) characters in length. But! When using a fully qualified path specification, the total length cannot exceed 260 characters.

In order to use the FQ path, you'll have to rename the file down to something more managable. Set the current directory to the path where the file is, rename it using only its filename to something shorter, then set the current directory back to what it was. You can then use the FQ path.

This is doable but I have another scenario...

I have a file list that include a FQ path. My program reads this list and tries to extract the directory from each FQ path listed. It does this using "Dim ParentPath as string = Directory.GetParent(LongPath).ToString)".
When this is executed I get "path is too long". Is there a .net function that can be used that ingores the length of the string I pass and give back the path?

Thanks

This has nothing to do with the .NET environment, rather it's a limit of Windows and NTFS. There is no function in the .NET BCL that will do this for you without going to the Win32 filesystem functions.

If you need it to ignore the filesystem limitations, you'll have to write a function yourself that parses up the FQ path string and returns what you need using simple string manipulations.

Ok. i have pased the FQ path string and created all folders but when I chdir(path) then do a file.create(filename) it still gives a path too long error. The file is 222charaters.

Any ideas here.

It was worth a shot, but it doesn't look like it's going to work, no matter what you do.

Repaint only sections of a screen?

Hey there,

I have a game plays sort of like risk. You pick up a unit piece and move it around and drop here or there and it processes everything, but I noticed that the screen has some delay in repainting (about 1 second on my computer), I believe the problem is that it is trying to paint the whole screen instead of what is being looked at (IE, the map takes up 10 screens, and the user moves only 1/2 a screen and it paints all 10 screens worth of info). Is there a way to control this? I would really help with the flow of the game if it didn't delay all the time... Thanks for any help and I'll be sure to post when the game is ready to launch early next year! Big Grin | :-D

Capture image in memory

Hey there, hang with me while I attempt to convey my problem better than on my other message board. I have a game plays sort of like risk. You pick up a unit piece and move it around and drop here or there and it processes everything, but I noticed that because of the dynamics of the game the screen has some delay in repainting the screen (about 1 second on my computer), but I do no need the map to be dynamic all the time. I was wondering if I could load in the dynamic map, take some sort of "screen capture" (though it's not a screen capture becuase the map is far larger than the screen) and display a static image. My other board said that screen capture can only get what's on the screen and I know that. But is there a way to grab it from memory, convert it to a static image, and display that instead? That's soo much for any help, and I'll be sure to leave a post when the game finally launches early next year! Big Grin | :-D

Conditional formatting DataGrid columns

I have a DataGrid on a Windows form that I populate using a DataSet object. Two of the columns may contain fields with Null values. When both fields in a row are Null, no problem, I display blank cells in the grid using a TableStyle object.
But if the first field in a row is not Null and the second one is Null, I would like to display in the second cell of the grid some text, such as "uknown", or "not applicable" (or maybe color the cell differently). Looping one by one through all DataGrid rows after populating the grid and examining cells data is not an option as I expect the grid to contain up to 2500 rows, so the whole process could be noticeably slow.

I first thought about using multiple table column styles, but I can't figure out how to switch from one style to another based data read at runtime.

I also tried this approach:

' populate the grid
objDGrid.DataSource = objDataSet
'
' define a currency manager
objCurMgr = CType(objDGrid.BindingContext(objDataSet, "openTasks"), CurrencyManager)
'
' define a Binding object attached to the "DataSource" 
' property of the DataGrid
If Not (mobjBndg Is Nothing) Then
   objDGrid.DataBindings.Remove(mobjBndg)
End If
mobjBndg = New Binding("DataSource", objDataSet, "openTasks")
objDGrid.DataBindings.Add(mobjBndg)

Outside the code portion of the form, I declared:

Private WithEvents mobjBndg As Binding

My idea was to use the Format and Parse events of the Binding object and change in code the formatting of data displayed in cells. I thought the Format event should fire once for each cell in a row when the DataGrid is being populated. But it never does. Why? Confused | :confused:

What am I missing or doing wrong? Is there a better way to accomplish what I want? Can anyone shed more light?

I Googgled with "DataGrid + binding + dynamic formatting" and got zilions of hits, but only examples of simple bindings of controls such as TextBoxes. I couldn't get any example of complex data binding and dynamic formatting of a DataGrid control.

Thank you in advance for any suggestions and hints.

Help me please.

hi uthen,

another solution using access vba...
i tried this in access VBA...just created a module & it seemed to work ok

Option Compare Database
Dim strarray, str As String
Dim s

Const test As String = "RemAAAARemRm2BBBBRm2Rm3CCCCRm3Rm4DDDDRm4Rm5EEEERm5Rm6FFFFRm6Rm7GGGGRm7Rm8HHHHRm8Rm9JJJJRm9RmAKKKKRmA"

Sub main()
strarray = Split(test, "")

For Each s In strarray
If s <> "" Then
Debug.Print s
End If
Next

End Sub

hope of some help Smile | :)

'call function from module returning array of parsed elements from string

Hi to you all,

I have to manage a network graph (nodes, links and their attributes),
but I don't know the best way to do it.
I found some examples using arraylist, some other examples using hashtables, while i've been using two dictionaries (nodes and links),
what do you think about that?
the tasks i'd have to perform are basically a conversion from a format to another, to sort the links to a couple of attributes and do some calculations.

thanks in advance!

how do i correctly convert a string containing a 32 bit hex value to a uint32,
i dont have any problem when the integer value of the hex would be a positive value
but im having problems when the hex value would represent a negative integer

How does a hex value represent a negative integer ? Does it start with a - ?

00000000 to 7FFFFFFF represent positive integer values and FFFFFFFF to 80000000 represent negative integer values

Christian Graus31-Oct-05 13:56

I thought so. You're trying to take an unsigned number ( FFFFFFF does NOT represent a negative number, necessarily ) and turn it into a signed number. The easiest way to do this would be to cast it, at a guess. Or do the conversion manually.
