Is it possible to convert the binary file to text file in C++ DLL through VB?
If yes, give me the idea to code that.

but if the pic es big the user need to surf on the pic.
I use a picturebox but the control don't have scroll bar.
What kind of control I can use to move on the image,
I thnik about if is posible with a click and drag move the image.
And if is possible make a zoom much better.
well c2.
Thank You

I don't know if it works... but you can put the imagebox into a GroupBox... and make some "Surf arrows" that would cause the ImageBox move in the GroupBox...

You've got to be kidding! What are you paying for this help?
Let's see. You get outside help to put this system together and your company will recognize who? Will reward who? Will not even know, nor care about, the massive amount of help you received from who?
Try going to RentACoder.com and putting together a consulting contract. Ya ain't gonna find anyone here to do write this.

i need to convert
#include "stdafx.h"
#using <mscorlib.dll>
using namespace System;
int _tmain()
{
unsigned char a1[16];
unsigned char a2[16];
unsigned int tempWRITE;
//FILE *in = fopen("c:/test.bin","r");
FILE *in = fopen("c:/test.bin","rb");
FILE *out = fopen("c:/new.txt","w");
while(!feof(in)) {
fread(a1,1,16,in);
a2[0] = a1[3];
a2[1] = a1[2];

hi, well here is an atempt since i'm not that great at c++!
Public Sub t_Main()<br />
<br />
'declare the variables<br />
Dim a1(16) As Char<br />
Dim a2(16) As Char<br />
Dim tempWRITE As Integer<br />
<br />
'use streamreader to open file<br />
Dim fs As StreamReader = New StreamReader("c:/test.bin")<br />
'read file into a1<br />
fs.Read(a1, 0, 16)<br />
fs.Close()<br />
<br />
<br />
<br />
<br />
a2(0) = a1(3)<br />
a2(1) = a1(2)<br />
a2(2) = a1(1)<br />
a2(3) = a1(0)<br />
a2(4) = a1(5)<br />
a2(5) = a1(6)<br />
a2(6) = a1(4)<br />
a2(7) = a1(7)<br />
a2(8) = a1(9)<br />
a2(9) = a1(11)<br />
a2(10) = a1(8)<br />
a2(11) = a1(10)<br />
a2(12) = a1(14)<br />
a2(13) = a1(12)<br />
a2(14) = a1(15)<br />
a2(15) = a1(13)<br />
<br />
'use streamwriter to write file<br />
Dim sw As StreamWriter = New StreamWriter("c:/new.txt")<br />
'write a2 to file<br />
sw.Write(Convert.ToString(a2), 0, 16)<br />
sw.Close()<br />
<br />
End Sub
just call t_Main() in a procedure or click of a button!
should be nice and easy!

how do you mean the outputs not right? if you change new.txt to new.bin it should be the same, have you put Imports System.IO at the top of your code. I can help you if you give me a better description of the problem?

Hi,
I am creating a visual studio add-in.
And I want to add 2 projects to a solution.
But I'm having a problem...
If I try to edit the following MSDN code:
<br />
Sub SolutionExample(ByVal dte As DTE2) <br />
' This function creates a solution and adds a Visual C# Console <br />
' project to it. <br />
Try <br />
Dim soln As Solution2 = CType(DTE.Solution, Solution2) <br />
Dim csTemplatePath As String <br />
' This path must exist on your computer. <br />
' Replace <file path> below with an actual path. <br />
Dim csPrjPath As String = "<file path>" <br />
MsgBox("starting") <br />
' Get the project template path for a C# console project. <br />
csTemplatePath = soln.GetProjectTemplate _ <br />
("ConsoleApplication.zip", "CSharp") <br />
' Create a new C# Console project using the template obtained <br />
' above. <br />
soln.AddFromTemplate(csTemplatePath, csPrjPath, _ <br />
"New CSharp Console Project", False) <br />
MsgBox("done") <br />
Catch ex As System.Exception <br />
MsgBox(ex.ToString) <br />
End Try <br />
End Sub <br />
like this:
<br />
Sub SolutionExample(ByVal dte As DTE2) <br />
' This function creates a solution and adds a Visual C# Console <br />
' project to it. <br />
Try <br />
Dim soln As Solution2 = CType(DTE.Solution, Solution2) <br />
Dim csTemplatePath As String <br />
' This path must exist on your computer. <br />
' Replace <file path> below with an actual path. <br />
Dim csPrjPath As String = "<file path>" <br />
MsgBox("starting") <br />
' Get the project template path for a C# console project. <br />
csTemplatePath = soln.GetProjectTemplate _ <br />
("ConsoleApplication.zip", "CSharp") <br />
' Create a new C# Console project using the template obtained <br />
' above. <br />
soln.AddFromTemplate(csTemplatePath, csPrjPath, _ <br />
"New CSharp Console Project", False) <br />
MsgBox("done 1ste project") <br />
<br />
soln.AddFromTemplate(csTemplatePath, csPrjPath, _ <br />
"New CSharp Console Project 2", False) <br />
MsgBox("done 2de project") <br />
<br />
Catch ex As System.Exception <br />
MsgBox(ex.ToString) <br />
End Try <br />
End Sub <br />
it doesn't work, Visual studio says that the solution already exists...
Is there a possibilty to dynamically add 2 class libraries to a solution?

Why do you need to add it dynamically?
|
|
|
|
|
Because I am making an automatic classgenerator. It automatically generates the classes from the selected SQL tables. So I need a class library for the autogenerated classes and I need another class library for the insert, update, delete ... statements. (I am programming 3 tier)
It works fine for just one class library but when I dynamically add another class library, visual studio says that the solution already exists and he can't create a second class library...

Hello,
I would like convert codes sources VB.NET into VB6. I have one application who uses components for VB6 only, so i can't migrate now to VB.NET
I saw good sources in your site ( like "http://www.codeproject.com/vb/net/autoupdate.asp") and i'm trying to use it in my application, but i have some problem with API/functions VB.NET.
Example :
How convert "Imports System.IO", "System.IO.StreamReader", "System.Net.WebClient", ...
What code must i use in VB6 ?
Thanks a lot for your help !
Bye
PS : sorry for my english, i'm french ...

You'll have to re-write your application from scratch. VB6 doesn't have any equivalent to the constructs you listed.
You can pretty easily convert VB6 code to VB.NET, not definately not the other way around. It'll take some serious work to do that. For instance, VB6 has no native web access built in. You'll have to use an external control in VB6 to do the same thing, like downloading a web page. About the best you'll be able to get is the basic idea and steps behind the process of what you want to do. Converting the code is next to impossible.

Ok, thanks for the answer !
I must find anothers things !

It might be possible to keep the VB.NET code and call it from VB6. Take a look at the VB Fusion section on MSDN.

I've never tried this myself. Nor want to. So, you're on your own from here.
