sql - Check SSIS Connection Manager's access to Server and DB -

-

I have a table like three fields, 

  server-name ---- - DB-Name ------- Flag ABC ------------------ ABC 123 XYZ ---------------- - 123XYZ EFG ------------------ ABCXY5 YUI ------------------- TER 675  < / Pre> 
 I save the details of that table in one variable and for each loop container, the connection manager of the data flow job for each loop container will be dynamically called the server and the DB name Is attached to Irdisht.                
 And if the above two conditions fail, then update the flag to "0" and send the related details to users. 
 
 How can I update the "Flag" field in the table based on the above two conditions?

why not

Can perform simple tests that try to make a connection 

  ... string connection string = "from your object var"; SqlConnection con = new SqlConnection (connectionString); ...

Wrap up to catch / update and update the flag on the basis of whether an exception occurs or not.

See how to use object variables in your script works

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
