Truncate GUICtrlCreateEdit data if too long

14 posts in this topic

I have an Edit that I send file names with their full paths to, and sometimes those paths are too long, and you can not see the file name, so I hacked out a way to cut out some info from the middle of the string so the file name is visible. I am hoping there is an optimized, built-in way to do this instead, my way seems inefficient and also doesn't fill the Edit consistently since some characters (like i) are skinnier than others (like w). My code is:

$statusinfo = GUICtrlCreateEdit("", 16, 96, 320, 21, BitOR($ES_AUTOVSCROLL,$ES_AUTOHSCROLL,$ES_READONLY))

.
.
.

$statusinfoshow=stringlen($formattedfile2)
if $statusinfoshow<=52 Then GUICtrlSetData($statusinfo, $formattedfile2)
if $statusinfoshow>52 Then 
    GUICtrlSetData($statusinfo, StringMid($formattedfile2,1,10)&"........."&StringMid($formattedfile2,$statusinfoshow-34,35))
EndIf

Is there a function to do that better? You have no idea how happy I was when I found _StringAddThousandsSep, my way SUCKED but worked, I am hoping the same can happen here.

Thanks!!

My projects:

  • IP Scanner - Multi-threaded ping tool to scan your available networks for used and available IP addresses, shows ping times, resolves IPs in to host names, and allows individual IPs to be pinged.
  • INFSniff - Great technicians tool - a tool which scans DriverPacks archives for INF files and parses out the HWIDs to a database file, and rapidly scans the local machine's HWIDs, searches the database for matches, and installs them.
  • PPK3 (Persistent Process Killer V3) - Another for the techs - suppress running processes that you need to keep away, helpful when fighting spyware/viruses.
  • Sync Tool - Folder sync tool with lots of real time information and several checking methods.

  • Audit Tool - Computer audit tool to gather vital hardware, Windows, and Office information for IT managers and field techs. Capabilities include creating a customized site agent.
  • CSV Viewer - Displays CSV files with automatic column sizing and font selection. Lines can also be copied to the clipboard for data extraction.
  • MyDirStat - Lists number and size of files on a drive or specified path, allows for deletion within the app.

NB: You can't open a file, Or Use Run() or do anything, becoz it's all fake!!

$FullPath    = "C:\WINDOWS\system32\IME\CINTLGNT\MORE\M\SOME.TXT"
$StringLeft  = StringLeft($FullPath, 10); 10, The number of characters to get
$StringRight = StringRight($FullPath, 10);10, The number of characters to get
;
MsgBox(0, "ShortPath", $StringLeft & "\..\" & $StringRight)

llewxam,

In response to the PM, it is easy to truncate labels:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

$spath = "C:\I am a very long path\Which needs to be\Shortened to fit\In the label.txt"

$hGUI = GUICreate("Test", 500, 500)

GUICtrlCreateLabel($sPath, 10,  10, 300, 30, $DT_PATH_ELLIPSIS)
GUICtrlCreateLabel($sPath, 10,  50, 300, 30, $DT_END_ELLIPSIS)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

WEnd

But this style does not seem to be applicable to edit controls - sorry! :)

Edit:

But this code will do the job without the style:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <Array.au3>
#include <StringSize.au3>

$sPath = "C:\I am a very long path\Which needs to be\Shortened to fit\In the control.txt"
$iMax_Size = 285  ; to allow for the vertical scroll bar

$aInfo = _StringSize($sPath)
If $aInfo[2] > $iMax_Size Then

    $aSections = StringSplit($sPath, "\")

    $sSmall_Part = "\" & $aSections[$aSections[0]]
    $sBig_Part = StringReplace($spath, $sSmall_Part, "")

    Do
        $sBig_Part = StringTrimRight($sBig_Part, 1)
        $aInfo = _StringSize($sBig_Part & "..." & $sSmall_Part)
    Until $aInfo[2] < $iMax_Size

    $sTrimmed_Path = $sBig_Part & "..." & $sSmall_Part

EndIf


$hGUI = GUICreate("Test", 500, 500)

GUICtrlCreateLabel($sPath, 10,  10, 300, 30, $DT_PATH_ELLIPSIS)
GUICtrlCreateLabel($sPath, 10,  50, 300, 30, $DT_END_ELLIPSIS)

GUICtrlCreateEdit($sTrimmed_Path, 10, 100, 300, 100)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit

Have fun,

Another Edit:

One thing. The styles leave the original path untouched - as you can see by using GuiCtrlRead on the labels - whereas my code actually truncates the string. So you would have to have some method of retrieving the original path later on - perhaps a 2D array of original/truncated and then use _ArraySearch?

Have fun,

Another Edit:

One thing. The styles leave the original path untouched - as you can see by using GuiCtrlRead on the labels - whereas my code actually truncates the string. So you would have to have some method of retrieving the original path later on - perhaps a 2D array of original/truncated and then use _ArraySearch?

M23

My thanks again to you as always, I decided to use the StringSize method and it looks good visually, but my app is now freezing. The app is a data backup tool (posted code to the forums previously, much has changed since. No need for the array to get the original file name back, I just do "$sPath=$formattedfile2" and off we go. On my first freeze after implementing your suggestion I got an error about an undeclared variable, so set a global for all variables just in case, but the freezing persists. Not yet sure what to make of that, but will get back to you when/if I find out why.

Thanks again though, the script looks very promising!

Ian

Edit-looks like it copies 874 files every time now, repeatable. Could it be a function calling itself too many times?

Edit2 - I take that back, get this - the smaller I set $iMax_Size the SOONER it freeses! I swear, I set to to 50, it bonks right away, I set it to 500 and it went further, I set it to 800 and it went further yet......I'll check StringSize for variables I have in use or anythign like that but doubt I'll find the answer there.....

llewxam,

Sorry, but I am off on holiday for a week early tomorrow and AutoIt definitely does not figure in my better half's plans. :)

My UDF does no file copying whatsoever - so I have no idea where that is coming from. All it does is measure the length of a string, nothing more. And as for freezing with smaller maximums..... I did not include any error-checking in the code - are you sure the StringSplit array is valid? I feel the problem must lie within the code you are feeding the UDF - but then I would say that, wouldn't I? :)

If you still have problems towards the end of next week, by all means let me have the complete code you are working on at that point and I will look at it after I get back.

Good luck,

M23

hehehe, enjoy the time off. No worries man, tell ya what - I just tried the $DT_END_ELLIPSIS suggestion and changed the Edit to a Label, no big deal and it works great, backup job finished with no problems. So, if you want to investigate this further when you get back let me know, I'll try any modification to the UDF you would like, but for now I'm making life easy. You do the same for the next week!

Thanks again

Sorry for not asking again about this a long time ago, but I am working on a totally different app now (code is HUGE and irrelevant anyway...) and still have issues with both posted solutions. The solution by Yashied will frequently have large amounts of white space to the right while truncating strings, and Melba23's will cause the script to lock up every time, after several successful trims. $DT_End_Ellipsis was SUCH an awesome solution but required I change my Edit to a Label, which then removed the box around that control, which I then had to create a Graphic control and use GUICtrlSetGraphic to hand-craft the lines, but the look is different on XP vs. Vista/7........jeeeeeez these workarounds become tedious!!! :)

So to sum up, do either of you guys see anything in your solutions to cause the issues I mentioned? If you must see some code for the examples I gave I could bang something out to demonstrate rather than post my current project, but what I am working on now is written from scratch sharing nothing from the app I was working on when I originally posted this question. I really doubt it is something I goofed up twice :( and besides all I am doing here is asking a function to trim a long path, kinda not something I can do wrong.

My Edit control shows files names/paths, some quite long, and the app deals with anywhere from 3,000 to 20,000 or more files, so each of your solutions gets banged on a lot during a single run.

Thanks for any suggestions, unfortunately I couldn't find anything in them myself to correct.

Though you won't be able to scroll the edit. If you have more lines than will fit in the edit you will need to draw all the text again to make it looks like it has scrolled up. But it's better than a label I guess.

I have used a 10000 element array to show it does work for large numbers. At the moment you can multiple select/unselect and clear - the items will stay highlighted (highlit?) as you scroll. You will no doubt need further functions, but I am fairly sure we could develop them farly easily.

Let me know what you think - I do not want to spend time on development if you would prefer another route. :)

That works well Melba23 :)

I would have preferred to do it slighlty differently, so that you have the child window, then create a child for that which is high enough to hold all the labels, then you create all the labels on that and when you scroll just move the grandchild up or down rather than rewrite all the labels. But I'm not going to do it, though I did a similar thing here.

Melba23, you again came up with an awesome answer! But, it actually helped me in a round-about way. When I did what you showed above it worked fine, but I am using a color scheme that $SS_BLACKFRAME looked bad with, and bad without too. So I was bummed out, thinking I was back in the same boat as before - a working solution but it was breaking the look of what I was doing. Then I thought about what you were doing, and it gave me a dirty little thought - keep my Edit control where I had it, put a Label control overtop of it but shrink it just enough that the Edit's borders were showing, and just write to the Label!! :( Yeah, I feel very dirty doing that, but hey - should I???? It works great because it is just using $DT_END_ELLIPSIS to truncate the string, and no user could possibly ever know that there are 2 controls stacked on top of each other there! hahahahaha

$statusInfo = GUICtrlCreateEdit("", 16, 96, 347, 21, $ES_READONLY)
GUICtrlSetBkColor(-1, 0xdce8ff)
$shadow = GUICtrlCreateLabel("", 20, 99, 335, 15, $DT_End_Ellipsis)
GUICtrlSetBkColor(-1, 0xdce8ff)

I thank you again for your time devoted to helping me out!

Ian
