Body
I am little bit confused in this program. I am new to Visual Basic but intermediate to C. Actually I want to get sub-string of string without using library function of Visual Basic. Here is the C source code I also given my VB code too. 1.The Program will get two inputs from user i.e A & B 2. Than Find the substring from B. 3. Finally Print the result. <pre class="lang-c prettyprint-override"><code>int i,j=0,k=0,substr=0; for(i=0;i<strlen(a);i++) { if(a[i]==b[j]) { j++; if(b[j]==0) { printf("second string is substring of first one"); substr=1; break; } } } for(i=0;i<strlen(b);i++) { if(b[i]==a[k]) { k++; if(a[k]==0) { printf(" first string is substring of second string"); substr=1; break ; } } } if(substr==0) { printf("no substring present"); } </code></pre> While my code is <pre class="lang-vb prettyprint-override"><code> Dim a As String Dim b As String a = InputBox("Enter First String", a) b = InputBox("Enter 2nd String", b) Dim i As Integer Dim j As Integer = 0 Dim k As Integer = 0 Dim substr As Integer = 0 For i = 0 To a.Length - 1 If a(i) = b(j) Then j += 1 If b(j) = 0 Then MsgBox("second string is substring of first one") substr = 1 Exit For End If End If Next i For i = 0 To b.Length - 1 If b(i) = a(k) Then k += 1 If a(k) = 0 Then MsgBox(" first string is substring of second string") substr = 1 Exit For End If End If Next i If substr = 0 Then MsgBox("no substring present") End If End Sub </code></pre> While compiling it gives following debugging errors. <pre><code> Line Col Error 1 Operator '=' is not defined for types 'Char' and 'Integer'. 17 24 Error 2 Operator '=' is not defined for types 'Char' and 'Integer'. 27 24 </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
