Using substring to pick the numeric value from a string failing

Hi,
I have a string like fffd_1234.com from this I need to pick the numeric value from which is in between the _ and . , for that I have wriiten the expression as
Reverse(SUBSTRING( REVERSE( "fgfg_asdd.com" ),
FINDSTRING(Reverse( "fgfg_asdd.com" ), ".", 1 )+1 ,findstring(
Reverse( "fgfg_asdd.com" ),"_",1 )-FINDSTRING(Reverse("fgfg_asdd.com"
), ".", 1 )-1))
This is throwing me the error or its giving me with the result with _123.

Why all the "reverse" calls? Do you expect underscores or periods to occur more than once in the file name?
This should work:
SUBSTRING("fffd_1234.com", FINDSTRING("fffd_1234.com", "_", 1) + 1, FINDSTRING("fffd_1234.com", ".", 1) - FINDSTRING("fffd_1234.com", "_", 1) - 1)

Picking the right values from tables - SQL (select statement)

Hi everyone,
I'm facing the litlle(?) problem in Oracle environment.
Let me explain:
I have two tables.
TABLE 1
Id1 | Val1 | Id2 | Val2
A | 44 | B | 36
B | 36 | A | 44
TABLE 2
Id | Name
A | New York
B | Seattle
I need to get from those tables, using SQL statement, result like this:
Id1 | Val1 | Name1 | Id2 | Val2 | Name2
A | 44 | New York | B | 36 | Seattle
NOTE !! Very important!! If in table 1 we have crossed the same values in fields IdX and ValX in two rows (like in example)- just one of them should be presented as a result.
I'm afraid it's a bit too complex. You, guys are my last hope.
Looking forward for any solutions.
Thanks in advance!

Process Order detail scheduling picking the std values from Phase.

I'm working on an Implementation scenario, where the Master Recipe contains only one Operation and one phase. After the Process order is created the basic start and End dates remain same. I did check the formula in the resource(on testing its working fine). I did check the control key, formula parameters, scheduling parameters of the process order. I have maintained the std values in the phase appropriately.
Still the process order basic start/end dates are same, even though the process order quantity is of any quantity.

How to extract an integer or a float value from a String of characters

Hi i have a problem getting to a float value within a string of characters..
for instance the string is
"numberItem xxxxxxxxx 700.0" (each x is a space..the forum wouldnt let me put normal spaces for some reason)
how do i store 700.0 in a float variable
remember the string is obtained from an inputfile
so far i got the program to store the inputfile data line by line in a String array..i tried tokenizing the string to get to the the float value but since i have mulitple spaces within my string, the token method only gets "numberItem" from the above String
This is all i have so far:
String c;
String Array[] =new String[g]; (i used a while loop to obtain g(the nubmer of lines in the file))
while((c=(cr.readLine()))!=null)
Array[coun]=c;
it would be reallllllllllllllllllllllllllllllllllllllly easy if there was a predefined method to extract numeric values from a string in java..

Not true.
Anyway why not use string split, split on spaces and grab the last element (which by the format you posted would be your 700.0)
Then there is the Float.parseFloat method.
It is easy.
And another thing why not use a List of Strings if you want to store each line? (And why did you post that code which doesn't really have anything to do with your problem?) Also in future please use the code formatting tags when posting code. Select the code you are posting in the message box and click the CODE button.

How to get the numeric value of DocTotal from UI API

When I hit the ADD button I need to get the DocTotal from the UI API !
All I have is the EditText which gives it in string and the problem is to double.Parse it
it's a pain to do it while there is CultureInfo related issue with it.
So It would be wise to get the numeric value directly from the UI API instead of getting the DocTotal by string and trying to convert it. So is there any way to get the numrci value of DocTotal from UI API ?

Hello Marc,
Here is a function which considering the Culture Info and always working. You can speed it up by using extending admininfo to global vairables, and loading the values at startup of the addon.
Use the oEditText.value.ToString() to convert into into the doulbe number:
Public Function _string2double(ByVal s As String) As Double
        Dim d As Double
' This part is fast, when regional settings equal to sap B1 settings:
        Try
            d = Convert.ToDouble(s)
            d = Math.Round(d, 6)
            Return d
        Catch
        End Try
' Speed up performance: extend CompaneService variables to global variables and query them at addon startup.
        Try
            Dim nfi As System.Globalization.NumberFormatInfo = System.Globalization.CultureInfo.CurrentCulture.NumberFormat
            Dim oCompanyService As SAPbobsCOM.CompanyService = oCompany.GetCompanyService()
            Dim oAdminInfo As SAPbobsCOM.AdminInfo = oCompanyService.GetAdminInfo()
            Dim sbodsep As String = oAdminInfo.DecimalSeparator
            Dim sbotsep As String = oAdminInfo.ThousandsSeparator
            If s.IndexOf(Space(1)) > 0 Then
                If oAdminInfo.DisplayCurrencyontheRight = BoYesNoEnum.tYES Then
                    s = s.Substring(0, s.IndexOf(Space(1)))
                Else
                    s = s.Substring(s.IndexOf(Space(1)), s.Length - s.IndexOf(Space(1)))
                End If
            End If
            Dim s1 As String = s.Replace(sbotsep, nfi.NumberGroupSeparator)
            s1 = s1.Replace(sbodsep, nfi.NumberDecimalSeparator)
            d = Convert.ToDouble(s)
            d = Math.Round(d, 6)
            Return d
        Catch
            Return 0
        End Try

How stop PS6 from removing the DPI value from an image when using "save for the web"?

How stop PS6 from removing the DPI-value from an image when using "save for the web"?
Example:
- Open a tif image, that contains a dpi value (resolution).
- Use the splice tool in PS6.
- Export the slices with "Save for web", as gif-files.
Then the dpi value is removed, the gif files has no dpi value (it's empty).
How can we stop PS6 from removing the dpi value when using "save for web"?
OR:
When using the slice tool, how can we save the sliced pieces without PS removing the dpi value?

you can make your art go a little bit over the bounds. or you can make sure your artboart and art edges align to pixels

Exchange Rate is picking the Maximum value, instead of valid from

Every first day of month we enter exchange rates for foreign currencies.
but when we make Purchase Order or any other payments in foreign currency, system is picking the maximum value, but not the value from Validity date.

Hello,
Thanks for your immediate response.
But my Question is for e.g.
on 01.01.2010 entered Exchange rate is 1 euro = 5.6954 SAR
on 01.02.2010 entered Exchange rate is 1 euro = 4.9653 SAR
if am posting document on 16.02.2010 it should pick the second value i.e., 1 euro = 4.9653 SAR, but system is picking the maximum value.

Get numerical values from 2D array of string

Hello!
I start by saying that I have a base knowledge of LabView. I'm using LabView 2011. I'm doing some communications test via Can-Bus protocol. As you can see in pictures of the block diagram and of the front panel that I've attached I'm using "Transmit Receive same Port" LabView example. It works very good but I would need to insert the 8 data bytes that I receive from the server in 8 different numerical variables so that I could use them to make some operations. How can I get numerical values from the 2D array of string that I attached?
Every example that you can provide is important!
Thank you very much!

Hi martiflix,
ehm: to unbundle data from a cluster I would use the function Unbundle(ByName)…
When you are new to LabVIEW you should take all the FREE online resources offered by NI on their website!

Accessing the email value from the iPhone AddressBook

Need some help getting the email value from the AddressBook. This is what I have so far ...
Used to open up the picker and limit to email only
-(void) browseButtonPressed:(id)sender
ABPeoplePickerNavigationController* controller = [[ABPeoplePickerNavigationController alloc] init];
controller.peoplePickerDelegate = self;
NSNumber* emailProp = [NSNumber numberWithInt:kABPersonEmailProperty];
controller.displayedProperties = [NSArray arrayWithObject:emailProp];
controller.navigationBar.tintColor = [UIColor blackColor];
[self presentModalViewController:controller animated:YES];
The delegate method in the same class
- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker
shouldContinueAfterSelectingPerson:(ABRecordRef)person
property:(ABPropertyID)property
identifier:(ABMultiValueIdentifier)identifier
NSString *email = (NSString *)ABRecordCopyValue(person, kABPersonEmailProperty);
NSLog(@"selected person: %@", email);
[[peoplePicker parentViewController] dismissModalViewControllerAnimated:YES];
return NO;
The NSLog prints the following ...
selected person: <NSCFType: 0x1d81c0>
Any idea why it's not printing a string rather I am getting NSCFType ?

Great Post. One of the few times that I was able to come to a conclusion about the code I need. Here is an example of the delegate method in reference to getting the email address.
- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
ABMultiValueRef emails = ABRecordCopyValue(person, property);
CFStringRef email = ABMultiValueCopyValueAtIndex(emails, identifier);
NSLog( (NSString *) email);
self.receiverEmail.text = (NSString *) email;
[self.tabBarController dismissModalViewControllerAnimated:YES];
return NO;

How to capture the selected values from module pool dialog list box !

Hi experts,
Can anyone help me out in capturing the values from the list box.
i am able to set the values in the list box.But i am not able to capture the selected value from the list box. Always the list box name is getting as "space"
I also tried in using the FM "VRM_GET_VALUES" but it is retireving all the values. Is there is any flag for filttering out the selected value.
Your inputs are appreciated.
Thanks,
Vijay.

Along with the PBO and PAI event, add a POV event in the flow logic of the screen
DEMO_DROPDOWN_LIST_BOX -is a good demo example.
PROCESS ON VALUE-REQUEST.
FIELD structure_name-field_name MODULE create_dropdown_box.
In the report :
MODULE create_dropdown_box INPUT.
SELECT carrid carrname
                FROM scarr
                INTO CORRESPONDING FIELDS OF TABLE itab_carrid.

            no_values_found = 2
            OTHERS          = 3.
IF sy-subrc <> 0.
ENDIF.
ENDMODULE.
In the layout, assign a Function Code , for eg : 'SELECTED' to the listbox and lets say name of the field is SDYN_CONN-CARRID. So in the PAI module,
MODULE user_command_0100 INPUT.
CASE ok_code.
    WHEN 'SELECTED'.
      MESSAGE i888(sabapdocu) WITH sdyn_conn-carrid.
ENDCASE.
ENDMODULE.
sdyb_conn-carrid will contain your selected field

Please help me .

You are not able to get the returned value because if you see the Remote object help you will realise you have to use result="resultfn()" and fault = "faultfn()"
In this you define what you wish to do.
More importantly in the remote object you need to define which method you wish to call using the method class like this
<mx:RemoteObject id="remoteObj" destination="sro" result="r1" fault="f1" >
     <Method name="javaMethodName" result="r2" fault="f2"/>
<mx:RemoteObject>
r2 is the function where you get the result back from java and can use it to send the alert.

How can I access the Attribute Values from the Search Region

Hi all,
I have a table which contains Company id, department id, and PositonId. For a particular Company and Department there may be multiple records.
I have to pupulate a table which contains the position and other details that comes under a particular Department and Position based on the selection in the Three comboBoxes.
Also I have to populate a select many Shuttle to add new postions and records under a particular Department.
I created a query panel *(Search Region)* for the serch and a table to display the data. That is working fine.
Now the issue is I am using a view criteria to populate the shuttle with two bind variables ie, DepartmentId and CompanyId.
If the serach will return a resuktant set in the table it will also pupulate the correct records, otherwise ie, if the if the serch result is empty the corresponding iterator and the attribute is setting as null.
SO I want to access the attribute values from the Search Region itsef to populate the shuttle.
I don't know how can I access the data from the Search Region.
Please Help.
Regards,
Ranjith

you could access the parameters entered in search region by the user as follows:
You can get handle to the value entered by the user using queryListener method in af:query.
You can intercept the values entered as described
public void onQueryList(QueryEvent queryEvent) {
// The generated QueryListener replaced by this method
//#{bindings.ImplicitViewCriteriaQuery.processQuery}
QueryDescriptor qdes = queryEvent.getDescriptor();
//get the name of the QueryCriteria
System.out.println("NAME "+qdes.getName());
List<Criterion> searchList = qdes.getConjunctionCriterion().getCriterionList();
for ( Criterion c : searchList) {
if (c instanceof AttributeCriterion ) {
AttributeCriterion a = (AttributeCriterion) c;
a.getValues();
for ( Object o : a.getValues()){
System.out.println(o.toString());
//call default Query Event
invokeQueryEventMethodExpression("#{bindings.ImplicitViewCriteriaQuery.processQuery}",queryEvent);
public void onQueryTable(QueryEvent queryEvent) {
// The generated QueryListener replaced by this method
//#{bindings.ImplicitViewCriteriaQuery.processQuery}
QueryDescriptor qdes = queryEvent.getDescriptor();
//get the name of the QueryCriteria
System.out.println("NAME "+qdes.getName());
invokeQueryEventMethodExpression("#{bindings.ImplicitViewCriteriaQuery.processQuery}",queryEvent);
private void invokeQueryEventMethodExpression(String expression, QueryEvent queryEvent){
FacesContext fctx = FacesContext.getCurrentInstance();
ELContext elctx = fctx.getELContext();
ExpressionFactory efactory = fctx.getApplication().getExpressionFactory();
MethodExpression me = efactory.createMethodExpression(elctx,expression, Object.class, new Class[]{QueryEvent.class});
me.invoke(elctx, new Object[]{queryEvent});

Java API to read the Encrypted Values from Windows Registry settings

Is there any Java API to read the Encrypted Values from Windows Registry settings ?
My Java Application invokes a 3rd party Tool that writes the key/value to windows registry settings under : “HKLM\Software\<3rdparty>\dataValue”.
This entry is in BINARY and encrypted with 3DES, using crypto API from Microsoft.
3rd party software to encrypt the data stored in registry it
either uses C++ code: and uses the call “CryptProtectData” and “CryptUnProtectData” or
If it is a .NET (C#) it uses the call “Protect” or “UnProtect” from class “ProtectData” of WinCrypt.h from the library “Crypt32.lib.
Note: The data is encrypted using auto-generated machinekey and there is no public key shared to decrypt the Encrypted data.
Since the data is encrypted using auto-generated machinekey the same can be decrypted from a .Net / C++ application using CryptUnprotectData or UnProtect() API of WinCrypt.h from the library “Crypt32.lib.
To know more about Auto-Generated MachineKey in Windows refer the links below
http://aspnetresources.com/tools/machineKey
http://msdn.microsoft.com/en-us/library/ms998288.aspx
I need to find a way in Java to find the equivalent API to decrypt (CryptUnprotectData) and Microsoft will automatically use the correct key.
But i couldn't find any informato related to Java APIs to enrypt or decrypt data using auto-generated machinekey.
Is there a way to read the encrypted data from Windows regsitry settings that is encrypted using the Auto-Generated Machine Key ?
Kindly let me know if Java provides any such API or mechanism for this.

If the symmetric key is "auto-generated" and is not being stored anywhere on the machine, it implies that the key is being regenerated based on known values on the machine. This is the same principle in generating 3DES keys using PBE (password-based-encryption). I would review the documentation on the C# side, figure out the algorithm or "seed" values being used by the algorithm, and then attempt to use the JCE to derive the 3DES key using PBE; you will need to provide the known values as parameters to the PBE key-generation function in JCE. Once derived, it can be used to decrypt the ciphertext from the Regiistry in exactly the same way as the CAPI/CNG framework.
An alternate way for Java to use this key, is to write a JNI library that will call the native Windows code to do the decryption; then the Java program does not need to know details about the key.
That said, there is a risk that if your code can derive the key based on known seeds, then so can an attacker. I don't know what your applicatiion is doing, but if this is anything related to compliance for some data-security regulation like PCI-DSS, then you will fail the audit (for being unable to prove you have adequate controls on the symmetric key) if a knowledgable QSA probes this design.
