In Java, how can I check whether a folder exists given some path?
Thanks
Vikram

File file1 = new File(folderLocation);

System.err.println("The folder exists...");

Checking to see if a folder exists

Hello,
I am trying to save a file to a directory and if the directory does not exist I want to create it. I have attached an image of a simple vi. My problem is that when I run the vi and the directory does not exist I get a pop-up error window #7 that says the file was not found. If I press continue my vi will behave normally and create the directory and file. The strange thing is, I did a search and found someone with this problem and there was an example file DirTest.vi that someone created. That file works fine, I do not get an error#7 pop-up window. But when I try to create the same vi on my machine I get the Error #7 pop-up window. I have LV version 8.0 and updated to 8.0.1 and I still have the same problem.
Thanks for any help.

This would be a better way to do what you're trying to do. You want to check the error of the File/Directory Info VI for that error code 7 that you get. This tells you that the file or folder doesn't exist, then you create it. This way, you won't have to turn off error handling. This is how I always check if a file exists.

The project could not be created,please check the webroot folder(it may overlap with an existing project)

Error msg: "The project could not be created, please check
the webroot folder (it may overlap with an existing project)." This
occurs in the CF/Flex Application Wizard Pproject Information
Window on a Flex3 application. I checked to make sure that there
were no overlapping applications and the message still persists.
There are old threads on this from Flex 2 but the problem still
exists in newly released Flex 3. Please help!

I can't help you with this, but you are not alone. A friend
of mine has exactly the same problem

I'm a Pro Tools user, who just did an "Archive and Install" installation of 10.5.8 over my 10.4.11 on my 2 Ghz G5, now Pro Tools won't launch. I checked the extensions folder and sure enough, the digidesign extensions were left behind. Can I revert back to the "Archive" of my 10.4.11 System from the "Previous Systems" folder? If not, what's the point of creating the "archive"?

Did you select "Preserve User Settings"?
Archive and Install installation automatically moves existing system files to a folder named Previous System, then installs Mac OS X again. (See tip 3.) You cannot start up your computer using a Previous System folder, nor can you "re-bless" the Previous System folder. (See tip 1.)
You can choose to preserve your user and network settings before installing. This option automatically moves existing users, Home directories, and network settings. This also skips the Setup Assistant after installation.
Note: Because the "Preserve user and network settings" option moves, not copies, existing users, Home directories, and network settings, from the Previous Systems folder to the newly installed System, these items will not exist in the Previous Systems folder after the Archive and Install is complete.

Hi all,
Please help me...
I have inputted quantity for tx MC 94 but when I input them into tx MC94, I met a message " Structure not yet maintained for this conbination characterstics". Step by step to show a error message as below:
Step 1: Launch MC 94
step 2: Enter Planning
Step 3: Enter Prod.Code. Material (ex: enter material code :0101010260008, this code is existed Prod.Code )
Step 4: Click on "Inactive Version " button
==> A error message is showed.
Please help me how to check a material does existed group code in system (which table to check it)?
How to record the message" Structure not yet maintained for this conbination characterstics" to catch up it in my program?
Thank in advance.

Karenloria,
1. Check in MC8C, which Infostructure is used for Planning type "Planning" or the one you are entering in the intial screen of MC94.
2. Using transaction MC63 for the infostructure identified in step 1, check the planning hierarchy maintained. If this product is not maintined maintain using MC62.
You can also check using SE16 transction the current infostructe records(Plan) for the table name = infostructure identified in step 1.

How can i check if a procedure exists in a certain database version

So today i became really frustrated after noticing that the Oracle SQL version on some computer I needed to work on was 10.1. The problem with that was that I needed a procedure called "xmlserialize". I browsed the documentation for it, but I didn't see anything like "since 11.0" or something similar.
So.. how can I see what is the first Oracle SQL version that supported some procedure?
For example, when I check a class definition for Java, I consult the javadoc :
http://docs.oracle.com/javase/7/docs/api/java/math/BigInteger.html
and there there's a field called "Since". For BigInteger ( it's just an example ), it says "Since: JDK1.1", so I know that if I'm using a JDK version earlier that 1.1, I won't have that class.
Is there some similar information for Oracle procedures/ functions/ features/ etc?

>
Let me be more explicit. I've searched for xmlserialize function.
The only place on the website that holds information regarding this function is this page:
>
To paraphrase sybrand - that's utter nonsense. I have never found only one reference to anything on the web.
Your question subject is

Error : Opening a rowset for "Sheet$" failed. Check that the object exists in the database.

Hi,
i am trying to load the data from excel sheet using For each loop container in ssis 2005.
But it gave me the below error:

That message usually means validation has failed;
Have any of the underlying tables changed? Data types, lengths, maybe even column ordering, etc...?
try this..
Right-click on the Data Flow Task and select Properties. Then set DelayValidation =TRUE.
Let us TRY this |

Thanks ETL.
Everything is fine..(Datatypes,length,orderings etc)
Already i have set

IS there any other problem?

Custom program for availability check and update for existing sale order at Item level(VA02)

Hi,
I came to know Bapi_Saleorder_Simulate can be used for availability check and update an existing sale order.but there is no sample program explaining the process.I have tried this by passing parameters ORDER_HEADER_IN , ORDER_ITEMS_IN ,ORDER_PARTNERS and ORDER_SCHEDULE_EX(for getting details),also i have assigned the sale document number ,custom document type(ZSO) in ORDER_HEADER_IN . while executing the BAPI I am getting the error external number range is not assigned for the document type ZSO . I am confused on seeing this error. It is possible to do availability check for existing sale order using this BAPI. Please explain how to achieve this.It will be really helpful if it is expalained with an example.
Regards,
Shanmuga

Hello, I think you may have been misinformed about this BAPI updating a sales order at item level. As far as I understand it this BAPI can be used to simulate the creation of a sales order which obviously would include and ATP check. This is why it is giving the error because it is simulating creation but you are entering a value in a field that should be automatically generated (i.e. the sales order number). For change the sales order at item level have you looked at BAPI_SALESORDER_CHANGE? I pretty sure this BAPI both updates sales order (header or item level) and can do an ATP first.
Points are always welcome if you feel an answer has been helpful.

How do I check if a table exists

I have some embedded SQL statements to create tables and indexes
in a database. These tables may or may not already be there. I
would like to be able to drop the table(s) first, then create
them. Unfortunately, an error is generated if I drop a table
that does not exist.
Can someone send me the proper SQL command to check if a table
exists before dropping it in Oracle?
TIA

How to check if an object exists and how to discard it?

Greetings,
I have a main GUI panel in a JFrame that creates a smaller JFrame with a progress bar and text area whenever a process is initiated. I've set the default close operation to DISPOSE_ON_CLOSE as when I set it to EXIT_ON_CLOSE the main GUI panel closes as well (!). But whenever I'm closing the smaller JFrame and initiate a new thread, then the same operation is perform in parallel 2, 3 ,4 times, etc. It seems that the object of the class ProgressGUI which carries all the components of the small panel is not disposed properly. So my question is how can I check if an object exists and if yes how can I discard it? Or in other words how can I discard the JFrame of the small panel without closing the main GUI panel as well?
thanks,
Thomas

I've set the default close operation to DISPOSE_ON_CLOSE thats right.
So my question is how can I check if an object exists Whenever you create an object, save its refrence somewhere, then just check
if(reference==null){
         //object does not exist
}else {
        //object exists
and if yes how can I discard it? Ensure that no references of the object to be discarded are remaining with any of the objects and then believe in 'Garbage Collector' to do the job! e.g. if there is only one reference to the frame (in your case) somewhere, you can just make an assignment like:
reference=null;by doing this, you have made the object a candidate for garbage collection. Rest is done by 'Garbage Collector', not you.
For cases like yours, it is better to make the small frame just once and whenever required just make the frame visible.
e.g.
JFrame smallFrame;
void showSmallFrame(){
    if(smallFrame==null)smallFrame=new SmallFrame(); //or something like that
    smallFrame.setVisible(true);
}Thanks!
