C# :: Extract Value From Stored Procedure That Takes A Parameter
Dec 17, 2014
I have a stored procedure, which I cannot change (it is used by older programs). It is passed an int of 15 and then an ID is generated and written to a database table. The created ID is then suppose to be selected and returned.
The INSERT does not seem to be working. I'm not getting the created ID value from my code, I am getting the value I passed to the procedure when I get to this
line of code "sessionID = sessionProcedureID.Value.ToString()";.
Below the stored procedure and my code.
/***************Stored Procedure***********************/
USE [testDataBase]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[MakeValue]
[Code] .....

How do you use a stored procedure with a WebGrid? Our coding standard say we cannot write sql statement directly in the code to include HTML.
[var Grid = new WebGrid(DB.Query("Select * from Menu")]
The above call must be a call to a stored procedure.

I'm trying to pass one dataset's result as a variable in another stored procedure and this is what I have so far:
DataSet dsID = StoredProcedures.GetID((int)Session["TypeID"]);
int IDValue = Convert.ToInt32(dsID.Tables[0].Rows[0]["ID"]);
DataSet dsRequest = StoredProcedures.GetRequest(IDValue);
But I get the error: cannot implicitly convert to system.dataset.

I have a school project in which need to create a function that takes a File Object as a Reference Parameter. Supposedly, it should allow me to read the first piece of data from others separated by a space from a file. The later be able to continue reading from the next piece of data.
I know how to set things up to read from the data file, such as using
Code:
#include <iostream> , and
Code:
ifstream inputFileName;
inputFile.open ("nameOfFile");
I also understand how to pass a variable by reference to a function. But I simply cannot put the two items together!
I tried using
Code:
void getFileInput (ifstream &); //parameter
getFileInput ("nameOfFile") // call
void getFileInput (ifstream &dataFileName)
In the function I used
Code:
ifstream inputFile;
inputFile.open (dataFileName);
I'm just not getting an understanding of this concept!

Write a function palindrome that takes a vector parameter and returns true or false according to whether the vector does or does not read the same forward as backward (e.g., a vector containing 1, 2, 3, 2, 1 is a palindrome, but a vector containing 1, 2, 3, 4 is not).
Code :
#include <vector>
#include <iostream>
using namespace std;
void palindrome(vector<int>);

My errors are at the end of the program in two function calls within the definition of the InsertByValue function. g++ does not seem to recognize NumArray as a valid parameter.
#include <iostream>
#include <assert.h>
using namespace std;
const int CAPACITY = 20;
/* Displays the content of an int array, both the array and the size of array will be passed as parameters to the function
@param array: gives the array to be displayed
@param array_size: gives the number of elements in the array */
void DisplayArray (int array[], int array_size);

I have a button that calls a delete stored procedure with only two parameters. I can run the stored procedure via SQL manager and know it works. But, when I call the stored procedure from a sqldatasource on the .aspx page I get this error: Procedure or function has too many arguments specified.
Here is my code:
<asp:SqlDataSource runat="server" ID="sqlAuthorsInfo" ConnectionString="<%$ ConnectionStrings:Authors %>"
ProviderName="<%$ ConnectionStrings:Authors.ProviderName %>"
SelectCommand="FindAuthors" SelectCommandType="StoredProcedure" DeleteCommandType="StoredProcedure"
DeleteCommand="Remove_Authors">
<SelectParameters>
[Code] ....
Here is how the stored procedure looks - it is very simple:
DECLARE @authorcode int, @authorid int
DELETE FROM Requests
WHERE authorcode = @authorcode
AND authorid = @authorid
What is wrong? How do I resolve this???

I currently have a program where, by either pressing Ctrl+N or by going to "File->New" in the menu a new file is prompted.
However, there are cases in my program where I would also like the "new file" protocol to be called when a user presses a button.
Is there some way of accomplishing this, or can the "new file" protocol only be called by the standard Ctrl+N or "File->New" calls?

Here's my function definition
bool validateNumber(string& text, int min = 0, int max = -1, bool useMin = true,
bool getValid = true)
The code takes the string text, and checks the make sure that the input is valid and safe to convert and use as a number. However, sometimes there is not min, and sometimes there is no max. The lack of min is done by using the parameter useMin, while the lack of max is done by max < min.
My predicament is the following call:
validateNumber(text, -2);
Now, max will be used, even though I don't want it. Ideally, I would want to do something like... int max = (min - 1), ... but that doesn't work. I also can't check to see if the parameter hasn't been changed (that I know of), because the following call would make it look like it hasn't
validateNumber(text, -2, -1);
So the question is, is there a way to do what I want, without having to add in a bool useMax parameter? Or is this my only option? I don't want to do that for simplicity, but if I have to, I have to.

I hope that this isn't an elementary question to you more experienced people, but I am having some trouble with my .DLL file. I haven't ever had a problem with compiling and linking it with my main project before, but it appears now some sort of problem has started. The message that appears is :
I have no qualms with posting my .DLL source, as it is not particularly long or complex. It seems the problem functions are the last two I've added ( load_sound( ) and play_sound( ) ).

Procedure to Compare 2 Strings with the following criteria
coding of the following function -
I have absolutely no clue where to start -
Given the following sets of numbers -
1154 1179 2154 2554 2484 2144 4515 1144 1517 4815 1481
Given the Index number of 1154
I want to search the numbers for the Index number of 1154
The search will return a True if I can find 3 or 4 same digits between the Index number and the 8 numbers
The search also have the following criteria -
meaning that -
1154 when compared to 1154 == true
1154 when compared to 1179 == false
1154 when compared to 2154 == true
1154 when compared to 2554 == false
1154 when compared to 2484 == false
1154 when compared to 2144 == false
1154 when compared to 4515 == true
1154 when compared to 1144 == true
1154 when compared to 1517 == true
1154 when compared to 4815 == true
1154 when compared to 1481 == true
the index number can also be of type - 1234, 1123, 1112, 1111

I have a std::vector<int> and I want to modify subset of the elements. I thought I might be able to use:
std::vector<int> a = { 1,2,3,4,5,6,7,8,9 };
std::vector<int> b(&a[3],&a[7]);
for(auto& each : b) {
each++;
}
for(auto& each : a) {
std::cout << each << "
";
}
but that didn't work. The elements of 'a' retain their original values. Then, I thought, "Ooo, maybe I could make 'b' a reference." Nope. What approach would be to access a subset of a vector for potential alteration?

I need to extract comments from a C file, which are usually marked with " /* This is a comment */ ". It seems to me that I need to calculate first at what position is the / and then ask it if on the very next position to the / operand is the *, if it is then I need check where is the next * and if / operand is immediately next to it. At last I need to take everything between values that the first and second * have. But I don't know how to write that in code.
This was supposed to be done in c++.

Suppose I have read a line from an ASCII file with fgets(). Now I want to parse the line, which looks something like this: Code: # John Q. Public et al. 2014, to be submitted The name, "John Q. Public" is what I want. However, the name can be anything, consisting of 1 or more tokens separated by spaces. it could be "John" Or "John Public", or "Thurston Howell the 3rd", or etc... Bascially, I need to get the entire substring between the first hash mark, and the "et al" in the line. I tried this: Code: sscanf(line,"# %s et al.",name); But I can only get the first token (which, in this case, is "John").
