I don’t know what you’re trying to accomplish but your code has a few logical bugs. Perhaps you intended to do s1.substr(i, 4) instead of s1.substr(i, i+4). The second argument of substr is length. Even after doing this you might enter infinite loop because the length of the string is increasing by 1 every-time you … Read more
GridView1.DataSource = Sabt; GridView1.DataBind(); Sabt seems to be single object. To bind DataGrid you need to have collection like List<JadvalSabtenam > or BindingList<JadvalSabtenam> Try that: List<JadvalSabtenam > dataSource = new List<JadvalSabtenam> {Sabt}; GridView1.DataSource = dataSource; GridView1.DataBind(); Reason for that is: What Grid should do with single object? When it’s collection each item is corresponding to … Read more
Yeah it’s a bit of a ridiculous use of linq to be honest, given that strings can be enumerated/indexed directly there isn’t any need to use linq to effectively turn them into a “char plus index the char is at” tuple.. The linqy bit would look like: int index = 0; foreach (var digit in … Read more
If you have an array declared like int a[N]; where N is some positive integer value then the valid range of indices to access elements of the array is [0, N). It means that for example this for loop for(i=1;i<=10;i++) { printf(“enter 10 nos. for arr[%d] :”,i); scanf(“%d”,&arr[i]); } must look like for ( i … Read more
Just reindent your code you will find strange { like the one after printf(“Positive”); Juste removing this strange { and fixing your coding style will be: #include<stdio.h> int main() { int x; scanf(“%d”, &x); if ( x > 0 ) { printf(“Positive”); if ( x % 2 == 0 ) { printf(“Even”); } else { … Read more
You can use the ternary operator: string test = “It’s a test”; string test2 = (test != “”) ? test : “0-length string”; 5 solved C# Shorten if statement
Modify your main menu as follows: int main() { while(1) { printIntro(); mainMenu(); printOutro(); } return 0; } And get rid of cout << mainMenu(); in printOutro() 2 solved Program closes after running twice [closed]
You should use the following code to make the ASPxGridView show data from this table: if (connection.State == ConnectionState.Closed) { connection.Open(); SqlCommand cmd = new SqlCommand(“Select * From YazHata order by HataAdi ASC”, connection); SqlDataAdapter da = new SqlDataAdapter(cmd); DataTable dt = new DataTable(); da.Fill(dt); ASPxGridView1.DataSource = dt; // <<<< ASPxGridView1.DataBind(); //<<<<< da.Dispose(); connection.Close(); } … Read more

You need to check for the validity of your array bounds and value of b. b should obviously be: (Pseudo code): MinBound <= b <= MaxBound In your case , you can do as below: void traps() { int a,b,r; cout<<“Deciding placement of traps”; for (a = 1; a <= 8; a++) { r = … Read more
Actually, if you print the value of x before and after calling: x = “test”; You will see that it has changed. By losing a track to your allocated memory, you face with memory leak here. Furthermore, printf prints a string that starts from the pointer position until it finds the string terminated ‘\0’ (0). … Read more
Update I’m not sure if the answer below made sense before the question was edited. But it definitely looks pointless after :-). It is a bit hard to say, but maybe swapping lines will help (and I guess there is no need for unchecked): progressBar1.Maximum = Convert.ToInt32(e.MaximumProgress); progressBar1.Value = Convert.ToInt32(e.CurrentProgress); 9 solved Value of ‘10000’ … Read more
