  • Inserting data into a Database

    - by Erebus
    SO I'm making a "basic" login file where a person logs in and the data that person entered on that form gets transfered to another form aka my database/table. I think the problems is here but I'll post the rest of the code. CREATE FUNCTION dbo.Function4 ( parameter1 int = 5, parameter2 datatype ) RETURNS Table1 TABLE (UserName, Password, Password_Confirmation, Assets) AS BEGIN INSERT INTO Table1 (UserName, Password, Password_Confirmation, Assets) VALUES (a,b,c,d); /*SELECT ... FROM ...*/ RETURN END This is the Login Form using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace Login_Basic { public partial class Form2 : Form { public Form2() { InitializeComponent(); } Form3 Delta = new Form3(); private void label3_Click(object sender, EventArgs e) { } private void Form2_Load(object sender, EventArgs e) { this.Hide(); } private void textBox6_TextChanged(object sender, EventArgs e) { } private void textBox6_KeyPress(object sender, KeyPressEventArgs e) { int i = Convert.ToInt32(e.KeyChar); if (!(Char.IsDigit(e.KeyChar) || Char.IsControl(e.KeyChar) || (e.KeyChar == '.' && this.Text.Contains(".") == false))) e.Handled = true; } private void button1_Click(object sender, EventArgs e) { Delta.Show(); //if (textBox3.Text.Equals("")) //{ // MessageBox.Show("Please enter your username"); //} //else //{ // this.Hide(); //} // if (textBox4.Text.Equals("")) //{ // MessageBox.Show("Please enter your password"); // } // else //{ // this.Hide(); // } // if (textBox5.Text.Equals("")) // { // MessageBox.Show("Please re-enter your password"); // } // else // { // this.Hide(); // } //if (textBox6.Text.Equals("")) //{ // MessageBox.Show("Please enter your amount"); // // } // else // { // this.Hide(); // } } private void button3_Click(object sender, EventArgs e) { this.Hide(); } private void textBox3_TextChanged(object sender, EventArgs e) { } private void textBox4_TextChanged(object sender, EventArgs e) { } private void textBox5_TextChanged(object sender, EventArgs e) { } private void panel2_Paint(object sender, PaintEventArgs e) { /*if (textBox3.Text.Equals("") && textBox4.Text.Equals("") && textBox5.Text.Equals("") && textBox6.Text.Equals("")) { button1.Enabled = false; } else { button1.Enabled = true; }*/ } } } Here's a "Pic" of my database http://s299.photobucket.com/albums/mm305/krsimms123/Code.jpg Thanks in advance (I'll try and check this every few hours so I can help explain anything)

  • Better alternative for PipedReader/PipedWriter?

    - by Esko Luontola
    I need to have a buffered char stream, into which I write in one thread and from which I read in another thread. Right now I'm using PipedReader and PipedWriter for it, but those classes cause a performance problem: PipedReader does a wait(1000) when its internal buffer is empty, which causes my application to lag visibly. Would there be some library which does the same thing as PipedReader/PipedWriter, but with better performance? Or will I have to implement my own wheels?

  • C++ static array leading to memory leak?

    - by MDonovin
    Lets say I have something like... void foo() { char c[100]; printf("this function does nothing useful"); } When foo is called, it creates the array on the stack, and when it goes out of scope, is the memory deallocated automatically? Or is c destroyed, but the memory remains allocated, with no way to access it/get it back except restarting the computer?

  • Have macro 'return' a value

    - by bobobobo
    I'm using a macro and I think it works fine - #define CStrNullLastNL(str) {char* nl=strrchr(str,'\n'); if(nl){*nl=0;}} So it works to zero out the last newline in a string, really its used to chop off the linebreak when it gets left on by fgets. So, I'm wondering if I can "return" a value from the macro, so it can be called like func( CStrNullLastNL( cstr ) ) ; Or will I have to write a function

  • Localized text in Java

    - by Eager Learner
    My requirement is to display localized text messages in a J2EE web application. I know J2EE provides very good support for this. My question is what is the practice followed to have the localized messages stored to be used by the application. If I want to display Japanese / Chinese kind of messages which are not like English like char sets how do we get that messages/text into the properties files or Database tables.

  • Unicode escaping in C/C++

    - by Geo
    Hi guys! I'm having a dispute with a colleague of mine. She says that the following: char* a = "\x000aaxz"; will/can be seen by the compiler as "\x000aa". I do not agree with her, as I think you can have a maximum number of 4 hex characters after the \x. Can you have more than 4 hex chars? Who is right here?

  • ruby sortby 3rd element in a multidimential array npot working properly

    - by Steven
    Hi, I'm using ruby to sort an array where each element in the array is another array. I have this: Data = Data.SortBy { |Info| info[3] } example data in this column: 3.1 2 5.65 -1 0.4 -9.43 -10.87 -2.3 It should sort this into: 5.65 3.1 2 0.4 -1 -2.3 -9.43 -10.87 But it comes out like this: 5.65 3.1 2 0.4 -1 -10.87 -2.3 -9.43 It's only comparing the first char of the float... not the whole number?

  • How to interpret binary data as an integer?

    - by StackedCrooked
    The codebase at work contains some code that looks roughly like this: #define DATA_LENGTH 64 u_int32 SmartKey::SerialNumber() { unsigned char data[DATA_LENGTH]; // ... initialized data buffer return *(u_int32*)data; } This code works correctly, but GCC gives the following warning: warning: dereferencing pointer ‘serialNumber’ does break strict-aliasing rules Can someone explain this warning? Is this code potentially dangerous? How can it be improved?

  • iPhone OpenGL scrolling background jumps when texture is drawn for first time

    - by Magnum39
    I have been fighting a problem for a while now and would appreciate any help anybody could give. I have a sprite that moves within a landscape. The sprite remains in the center of the screen and the background moves to simulate that the sprite is moving within the landscape. I have split the landscape into sections so that I only draw the sections of the landscape that I need (are on screen). The Problem: As a new texture section of the screen appears on the screen (is drawn for the first time) the movement jumps. Almost like a frame is missed. I have done some timing experiments and I do not thinks a frame is missed. My processing is well below the 30fps that I have the animation set to. It only happens the first time the texture section is drawn. Is there something extra that is done the first time a texture is drawn? Here is the code: - (void) render{ // Sets up an array of values to use as the sprite vertices. const GLfloat sVerts[] = { -1.6f, -1.6f, 1.6f, -1.6f, -1.6f, 1.6f, 1.6f, 1.6f, }; static const GLfloat sTexCoords[] = { 0.0, 1.0, 1.0, 1.0, 0.0, 0.0, 1.0, 0.0 }; glDisableClientState(GL_COLOR_ARRAY); glEnableClientState(GL_VERTEX_ARRAY); glEnableClientState(GL_TEXTURE_COORD_ARRAY); // Setup opengl to draw the object in correct orientation, size, position, etc glLoadIdentity(); // Enable use of the texture glEnable(GL_TEXTURE_2D); glVertexPointer(2, GL_FLOAT, 0, sVerts); glTexCoordPointer(2, GL_FLOAT, 0, sTexCoords); // draw the texture // set the position of the first tile float xOffset = -4.8; float yOffset = 4.8; int i; int y; int currentTexture = textureA; for(i=0; i<2; i++) { for(y=0; y<2; y++) { // test for the texture tile on the screen if not on screen then do not draw float localX = xOffset+(3.21*y); float localY = yOffset-(3.21*i); float xDiff = monkeyX - localX; float yDiff = monkeyY - localY; if(((xDiff < 3.2) && (xDiff > -3.2)) && ((yDiff <2.7) && (yDiff > -2.7))) { // bind the texture and set the vertex data pointers glBindTexture(GL_TEXTURE_2D, spriteTexture[currentTexture]); // move to draw position for the texture glLoadIdentity(); glTranslatef((localX+self.positionX), (localY+self.positionY), 0.0); //draw the texture glDrawArrays(GL_TRIANGLE_STRIP, 0, 4); } currentTexture++; } } }

  • PHP: constant as variable in function

    - by m4recek
    I'm trying to use constant as a function paramter, is it possible to check type of this constant. Example of what I want: class ApiError { const INVALID_REQUEST = 200; } class Response { public function status(ApiError $status) { //function code here } } USE: $response = new Response(); $response->status(ApiError::INVALID_REQUEST); This shoud check that given $status is constant of class ApiError. Is something like this possible?
