Hello, This Taiming and I am a serious C++/MFC developer with 15 years experiences.
Please let me know what problems you have met in AES encryption.

i am having trouble in AES code implementation in c++.Can any one help in c++ coding point of view
thank you
|
|
|
|
|
|
i have seen these web pages and code it according to that algorithm
i am now in final position in that code and the problem is that it is not encoding correctly and decoding as well so could you help me in that case
thank you very much

Without seeing your code neither I nor any other here can help.
If you just need working code, use an existing implementation.
Otherwise show your code and what you have tried / where it fails. To do this, edit your question and add the relevant code formatting it using the 'code' option above the edit window (should be not too much code).
Another tip is using an existing implementation with the same arguments and comparing the results. So you can detect if encryption, decryption or both are failing.

[Note: Enquirer has send a mail to me containing the code]
You had asked for help in a public forum. Then you should let others participate in the discussion.
But the complete code would be too much to be posted here and I have no time to step through that amount of code. Especially because it does not contain comments and begins with the inclusion of other source files which is bad C/C++ style.
If you find someone who can help you should at least tell which of these "web pages" has been used by you and which code parts has been written by you or has been copied.

Write a simple expression evaluator that takes a string like the following as input: 1+2*(3+4).
-Only integers need to be supported
-The following operators should be supported: +, -, *.
-Expressions within parenthesis should be evaluated first.
-Then the resulting expressions should be evaluated from left to right (no operator precedence)
-Example:
4+(4-(2*3)+1)+4 = 7
The code should be written in such a way to support additional operators.
Assume the existence of a function tokenise, which could take a string and return an array of strings, for instance
tokenise(‘1+(2*3)+4’) would return [‘1’,’+’,’(‘,’2’,’*’,’3’,’)’,’+’,’4’]
and the functions isNumber and asNumber which would return a Boolean and integer respectively on a single string input.

Your homework should serve the purpose that you learn something. And that something isn't supposed to be how to get other people to doing your homework for you.
Your assignments will get more difficult over time - so if you don't start doing them yourself now you'll never be able to.
So sit down, think about it and try something. If you then encounter a specific problem, feel free to ask - that's the idea of these forums.
Also, there are a lot of articles here on CodeProject about expression evaluation. Take a look at those if you struggle to find a starting point.

I use Visual Studio 2012 and Microsoft DirectX SDK (June 2010). I created an applicatin with a 3d cube as an object. In the example that I use it is moved the point of view of the camera.
In my case I would like to move the object by the keaboard along X and Y axis without moving the camera view.
Could you please help?
Here is my code:
...
CubeDemo::CubeDemo(HINSTANCE hInstance, std::string winCaption,
D3DDEVTYPE devType, DWORD requestedVP)
: D3DApp(hInstance, winCaption, devType, requestedVP), MAX_SPEED(1500.0f), ACCELE(1000.0f)
{
// 5 units off the ground.
mCameraHeight = 5.0f;
buildVertexBuffer();
buildIndexBuffer();
onResetDevice();
InitAllVertexDeclarations();
}
...
void CubeDemo::updateScene(float dt)
{
// One cube has 8 vertices and 12 triangles.
gDInput->poll();
// Check input.
if( gDInput->keyDown(DIK_W) )
{
// Code for moving the 3D object along X axis???
}
if( gDInput->keyDown(DIK_S) )
{
// Code for moving the 3D object along Y axis???
}
buildViewMtx();
}
void CubeDemo::buildViewMtx()
{
D3DXVECTOR3 pos(10, 0, 10);
D3DXVECTOR3 target(0.0f, 0.0f, 0.0f);
D3DXVECTOR3 up(0.0f, 1.0f, 0.0f);
D3DXMatrixLookAtLH(&mView, &pos, &target, &up);
}
void CubeDemo::drawScene()
{
HR(gd3dDevice->Clear(0, 0,
D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, 0xffffffff, 1.0f, 0));
HR(gd3dDevice->BeginScene());
HR(gd3dDevice->SetStreamSource(0, mVB, 0, sizeof(VertexPos)));
HR(gd3dDevice->SetIndices(mIB));
HR(gd3dDevice->SetVertexDeclaration(VertexPos::Decl));
D3DXMATRIX W;
D3DXMatrixIdentity(&W);
HR(gd3dDevice->SetTransform(D3DTS_WORLD, &W));
HR(gd3dDevice->SetTransform(D3DTS_VIEW, &mView));
HR(gd3dDevice->SetTransform(D3DTS_PROJECTION, &mProj));
HR(gd3dDevice->SetRenderState(D3DRS_FILLMODE, D3DFILL_WIREFRAME));
HR(gd3dDevice->DrawIndexedPrimitive(D3DPT_TRIANGLELIST, 0, 0, 8, 0, 12));
HR(gd3dDevice->EndScene());
HR(gd3dDevice->Present(0, 0, 0, 0));
}

You move an object by repainting it at successive different points of the view screen.

I know but I need any example or tutorial easy to import in my code.

Then you need to use Google to search for them.

What is the main purpose of this forum then? I thought that using forums people could reach the needed information faster. Unfortunately here the situation is different.

It is to help people with problems in the code that they write themselves. It is not a coding service, or a Google substitute. Since you do not have any code written, and I do not have a tutorial or sample code, then Google is the best place to look.

You need to TRASNLATE the object's POSITION.
while (DIK_W)
for(i=0; i < iMax; i++)
{
D3DXVECTOR3 pos(10, i, 10);}do
Or something like that ...

Thank-you for reply.
But I have already implemented it for Circle Vs. Circle.
I am searching for

I have successfully added more than one items in listbox but i can not play them. the player is playing only first file. i want it to play next song when i click next button and previous song when i click previous button.

This is the Managed C++/CLI forum. You probably need a different forum for your question.
|
|
|
|

I am writing a managed WPF Application. It is compiled against 'AnyCPU' as is common with C#.
I would like to add/develop a C++/CLI component to my app.
However C++/CLI is bound to an architecture (x86/x64/arm).
Is there a... relatively easy way for me to ship all 3 architecture and have the system load the right DLL at runtime?
|
|
|
|
|
You can try using the AddDllDirectory[^] method as the start of your application and add a directory containing the library for the current architecture. Just read the notes lower on the page on how to add the path to the default paths.
What do you get when you cross a joke with a rhetorical question?
The metaphorical solid rear-end expulsions have impacted the metaphorical motorized bladed rotating air movement mechanism.
Do questions with multiple question marks annoy you???
