[StarinschiAndrei]

Hi everyone,
Could anybody help me how to replace space with 60h ?
I'm working on integration with an API , if a send a string that contain " "(space) the API replace with +
Based on the documentation description :"NamePLU - 30 symbols for article's name plus separator for MU=60h"

If PLUName.Contains(" ") Then
        PLUName= Regex.Replace(" ",PLUName,"\<")
    End If

You don't need to escape the “<"

 PLUName= Regex.Replace(" ",PLUName,"<")

 

[StarinschiAndrei]

You don't need to escape the “<"

 PLUName= Regex.Replace(" ",PLUName,"<")

Where is the "&" from? could you post the project?

I think it is useless to post the project , because my app communicate with an API witch is connected to a cash register.
This is the the documentation

<Command Name="SellPLUwithSpecifiedVAT" CmdByte="0x31">

Below you can see the main part of communication

Sub Submit_Action(command As String)As ResumableSub 
    'Dim command As String = "SellPLUWithSpecifiedVat(NamePLU=Article1,OptionVATClass=A,Price=10.2,Quantity=1,DiscAddP=0,DiscAddV=0)"
    Dim command As String = command' "CashPayCloseReceipt()"
    Dim su As StringUtils
    command = su.EncodeUrl(command, "UTF-8")
    Dim j As HttpJob
    j.Initialize("",Me )
    j.Download("http://localhost:4444/" & command)
    Wait For(j) JobDone(j As HttpJob)
    If j.Success Then
        Log(j.GetString) 
        Return Code
    End If
    j.Release
End Sub

Public Sub sellItem(PLUName As String,VATRate As String,UnitPrice As String,quantity As String,DiscProc As String,DiscVal As String) As String
    If PLUName.Contains(" ") Then
        PLUName= Regex.Replace(" ",PLUName,"<")
    End If
    Return $"SellPLUWithSpecifiedVat(NamePLU=${PLUName},OptionVATClass=${VATRate}$,Price=${UnitPrice},quantity=${quantity},DiscAddP=${DiscProc},DiscAddV=${DiscVal})"$
End Sub

I mean that you post a snippet like this

 Dim PLUName as String="TEST 3"
 PLUName= Regex.Replace(" ",PLUName,"<")
 log(PLUName)

what is the result?

Here is the log result : TEST<3
And here is the printed line by device :

 

[Daestrum]

Can you not just use

PLUName = PLUName.Replace(" ","+")

As you said it replaces spaces with '+' not a '<'

 

[teddybear]

Here is the log result : TEST<3
And here is the printed line by device :
View attachment 141760

Try to send "TEST<3" to printer. see what result is?
The ECR prints TEST<3, isn't it the resullt you want?

 

[StarinschiAndrei]

Can you not just use

PLUName = PLUName.Replace(" ","+")

As you said it replaces spaces with '+' not a '<'

Here is the result :

 

[Daestrum]

As it is sent to a web address you may find you need to send

PLUName = PLUName.Replace(" ","%20")

 

[StarinschiAndrei]

As it is sent to a web address you may find you need to send

PLUName = PLUName.Replace(" ","%20")

thank you ! ! ! it's working

 

[Daestrum]

Have a look at url encoding for which chars can appear in a web address line.

 

[DonManfred]
