Hello Friends, Is it is possible to open visual studio project Win32 Console based application on visual studio .net 2005. Kindly respond to query. From Phijo:):)

Private Declare Function concat Lib "d:\StringConcat1.dll" (ByVal Text1 As String, ByVal Text2 As String) As String Private Sub Command1_Click() Text3.Text = concat(Text1.Text, Text2.Text) a = Len(concat(Text1.Text, Text2.Text)) MsgBox a End Sub The function of the vb code is given below. The form has three text fields a) The first text field , enter the first string b) The second text field , enter the second string c) The third text field, concatation of the two string i.e result of the two strings is shown in third text field d) One Command button at the bottom of the form. When we call "StringConcat1.dll" dll the value entered through the two text fields is send as a argument by value to the dll and Concatenation of the strings is done in C++ . the dll code is given below "test.cpp" #include char* __stdcall concat(char *string1 , char *string2) { return strcat(string1,string2); } the def is given "test.def" LIBRARY StringConcat1 EXPORTS concat @1 When I debug the code , the Concatenation is done in C++ but when the result is given to vb code ie front end only the first string that is entered in the first text is shown only as the output in the third text field. for example text1 : india text2 : people result text3 : india ( but the result should be indiapeople after the concatenation is done in C++(i.e dll does the function for concatenation , but the result shown is here is only "india"). Kindly note the point: the C++ code works perfectly. After computation ie Concatenation , the result is not shown in the vb code only text1 input is shown in text3 field.

In MFC wizard I have created a dialog form with two EditBoxs(IDC_EDIT1 and IDC_EDIT2). m_var1 and m_var2 are type unsigned integer. The type of the two edit boxes are of unsigned integer data type:). The names of the member variables are m_var1 and m_var2. Their is a Button on the Dialog form Kindly observe the code given void CMFC_7Dlg::OnButton1() { // TODO: Add your control notification handler code here UINT abc = m_var1; m_var2 = abc; UpdateData(FALSE); } the problem is that when click the button1, the value entered in IDC_EDIT1 is not assigned to the temporary variable abc. When I debug the code, the value assigned to abc is zero. For example if enter a unsigned value 23 , the value is not assinged to the variable abc. Kindly observe the code which is given below void CMFC_7Dlg::OnButton1() { // TODO: Add your control notification handler code here UpdateData(TRUE); m_var2 = m_var1; UpdateData(TRUE); } In the above code, the value enter in IDC_EDIT1 is not transferred to IDC_EDIT2 even though m_var1 and m_var2 are both unsigned integer data type. Kindly observe the code which is given below void CMFC_7Dlg::OnButton1() { m_var2 = m_var1; } In the above given code, the direct assinged of m_var1 to m_var2 is not possible. When I debug the program , only zero is assinged to m_var2. My question is why the value enter the IDC_EDIT1 is not shown in IDC_EDIT2? Can any one please help me in this matter. :) -- modified at 6:01 Tuesday 14th March, 2006

Hello Friends, I have a question . It is possible to call a second dll from the First Dll in VC++ application. Case 1: For example I a have dll called Sample A dll , then I have a second dll Sample B dll . It is possible to call Sample B dll from Sample A dll? All dlls are created using win32 dynamic DLL in VC++ platform. Can any one tell me what are the merits and demerits of such a method ? Case 2: To avoid such a situation is it possible to include the functionality the second dll in the first dll, so that calling a second dll from the first dll can be eliminated completely. Can any one tell me which of two Cases ie Case 1 and Case 2 is easy and more Reliable. :) :) -- modified at 2:22 Wednesday 22nd February, 2006
