How to check the given path is existing or not using sp_cmdshell

Hi All,
I am passing one path to the stored procedure, before executing code i want to check whether the path is given existing or not .
By using sp_cmdshell we can know whether files are there are not but in case of my scenario i want to know the directory(folder) is existing or not because the source folder may be blank so it will not get the files there so stored procedure returning the
File Not found as output.
following is the code i am trying to retrieve this please suggest any other way to solve it.
Create table #tableExists (isValid varchar(255))
Declare @path varchar(255)='DIR "C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA "/B'
INSERT INTO #tableExists
EXEC xp_cmdshell @path
select * from #tableExists
Regards,
Niraj Sevalkar

You can try the other two undocumented extended stored procedures as well:
--EXEC master.dbo.xp_subdirs @pathName
EXEC Master.dbo.xp_fileexist @pathName
EXEC Master.dbo.xp_DirTree @pathName,1

cmd.CommandText = "SELECT count(*) from tab where tname = 'OPC_GROUP'";
cmd.CommandType = CommandType.Text;
string strnum = cmd.ExecuteScalar().ToString();

Send a request to the server somehow, so that the server is aware of this. AJAX may be very useful in this if you want to do this asynchronously.
its very urgently This is irrelevant information. That's your problem. We don't care less or more. Some users here will even refuse to help you if you're putting pressure.

How to set the File Path to run a javascript using Plugin Code?

Hi All,
Im new to Indesign Plugin Development.Can any one help me out with my problem.
What i want to do is to run a javascript using Plugin Code.When i went through this forum i was able to find out that i should use the IscriptRunner Class to automate this.I could also figure out that the Member Function to use is "CanHandleFile" &"RunFile".
The first parameter in CanHandleFile & RunFile Member Function is to specify the path of the JavaScript File i suppose!I could also find out that IDFile has to used to set the file path Information.
But im clueless how to set the Javascript FilePath using IDFile.Can any one help me how to do this?Any Code Snippets Please?
Waiting for reply.
Thanks

Hi, Andreas Can you explain this in detail? I found it in your post before. The content of elements are returned through the Characters callback function: From ISaxContentHandler.h: /** Receives character data The parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks. But all characters in any single event must come from the same external entity so the Locator provides useful information. Note some parsers will report whitespace using the IgnorableWhitespace() method rather than this one (validating parsers must do so). @param Chars The characters from the XML document. */ virtual void Characters(const PMString& chars) = 0; What i have done is implement my own SAXContentHandlerServiceBoss, and in my file XXXSAXContentHandler.cpp, I override the fonctions StartElement, EndElement, and Characters() like below: I add the PMString xmlData to collect the file content: class XXXSAXContentHandler : public CSAXContentHandler { void XXXSAXContentHandler::Characters(const WideString& chars) { xmlData.Append(chars); } void XXXSAXContentHandler::StartElement(const WideString& uri, const WideString& localname, const WideString& qname, ISAXAttributes* attrs) { xmlData.Append("<"); xmlData.Append(localname); xmlData.Append(">"); } void XXXSAXContentHandler::EndElement(const WideString& uri, const WideString& localname, const WideString& qname) { xmlData.Append("</"); xmlData.Append(localname); xmlData.Append(">"); } } and in my program, I use the code below to call the fonction I overrided, but I dont know how I can get the String xmlData I defined in the XXXSAXContentHandler.cpp InterfacePtr<IK2ServiceRegistry> serviceRegistry(gSession, UseDefaultIID()); InterfacePtr<IK2ServiceProvider> xmlProvider(serviceRegistry->QueryServiceProviderByClassID(kXMLParserService, kXMLParserServiceBoss)); InterfacePtr<ISAXServices> saxServices(xmlProvider, UseDefaultIID()); InterfacePtr<ISAXContentHandler> saxHandler(::CreateObject2<ISAXContentHandler>(kXXXSAXContentHandlerServiceBoss)); saxHandler->Register(saxServices); bool16 parseFailed = saxServices->ParseStream(readStream, saxHandler); Can you give me any help? Thanks and regards!

Hi,

Not memory, but storage space.
Connect your iPad to your computer. Launch iTunes. Select the Summary tab. Storage space available at the bottom of the iTunes page.

HELP !!! How to check the size of an object in Photoshop ?

Hello,
I'm using Photoshop CS 3 to design a website. I used several shapes such as rectangle, line or ellipse of different size. Probably it is a stupid question but I don't know how to check the size of an existing rectangle. I tried free transform tool that selects my rectangle but doesn't show its size. Then I made a selection with rectangular marquee tool but I see nowhere the size of the selected area.
If you know the name of such a tool please help me !
Have a nice day !

Web images are all pixels. View at 100% at pixel view. that is your exact size

How to check the number of licences for ODI

Hi,
I would like to know , how to check the number of licences exists for my current OID.
ODI Version: 11.1.1

ODI licensing is similar to Oracle DB licensing. Its licensed by the number of cores in your target database.
So, count the number of CPUs in your target box. Multiply them by the core factor (x86 vs sparc, etc) and then match with the paperwork you have :D

My problem:
1)
I am not able to write to the file. I want to know, where i am going wrong.
It is giving error message like
"Canot resolve Symbol: temp,"
But, FileWriter Constructor should accept a File type parameter.
here temp is a file parameter.
If i am not using file=new file();
i can't delete the file after the use. i.e if i use
PrintWriter p = new PrintWriter(new BufferedWriter(new FileWriter("cute.txt",true)));
how can i delete cute.txt after the use?
2)
I am not able to write to the text file. file is created but, a blank file.
"Hello" is not written into the text file.
can anyone help me in this regard
Thanks in advance
Ashvini

Thank you Ram,
But, i want to create a text file in Append mode.
for that i used
FileWriter fos = new FileWriter(temp,true); But, it is not accepting FileWriter constructor in
this format. if i use
FileWriter fos = new
FileWriter("c:/ash/cute.txt",true); it works fine. !!!!!Here's the javadoc
public FileWriter(File file,
boolean append)
throws IOExceptionConstructs a FileWriter object given a File object. If the second argument is true, then bytes will be written to the end of the file rather than the beginning.
Parameters:
file - a File object to write to
append - if true, then bytes will be written to the end of the file rather than the beginning
Throws:
IOException - if the file exists but is a directory rather than a regular file, does not exist but cannot be created, or cannot be opened for any other reason
Since:
1.4
Are you using jdk.13 or lower ?
>
ONe more doubt, Does flush method deletes a file?
if not, then i need to use
File temp=new File("c:/ash/cute.txt");
FileWriter fos = new FileWriter(temp,true); //which
is again a problem
if(temp.delete())
out.println("File is deleted");
}I don't know whether i am taking it wrong ! or
anything wrong with my coding ! but, after creating
and writing data into a text file. I must delete it
as it contains confidential informations.
Regards,
Thanks.'flush' writes to a file immediately. Else you should explicitly call 'flush' to write contents from buffer to underlying source.
javadoc again
PrintWriter
public PrintWriter(Writer out,
boolean autoFlush)Create a new PrintWriter.
Parameters:
out - A character-output stream
autoFlush - A boolean; if true, the println, printf, or format methods will flush the output buffer
cheers,
ram.
Question; What do you gain by opening a file, writing to it and deleting it in the same program ?

How to check the verity version in our PeopleSoft Installation?

How to check the verity version in our PeopleSoft Installation? I am not sure if the verity is installed or not and also if installed what is the version?

yes. it says the version is 5.0.1
Is there any difference in installation or configuration when the app and web server are in same machine and when the app and web server are installed in different servers?
