  • html/css: set div bounding box to window height

    - by noamtm
    It looks like I'm missing something basic. I want a certain DIV to have the height of the window. The effect should be that there's never any need to scroll down. Do I have to use JavaScript? I was told that it's possible with css, but I can't find the relevant property - or I'm doing something wrong.

  • Autopopulate from Select box from database

    - by Chris Spalton
    hope you can help, please forgive any poor coding or anytihng, I'm new to this and just hacking my way through to get things to work. That said, on one of my projects I have this code, which successfully populates the dropdown from a database when the page is loaded: <select name="Region" id="Region"> <option value="">-- Select Region --</option> <?php $region=$POST['Region']; if ($region); { $regionquery = "SELECT DISTINCT REGION FROM Sales_Execs "; $regionresult = mysql_query($regionquery); while($row = mysql_fetch_array($regionresult)) { echo "<option value=\"".$row['REGION']."\">".$row['REGION']."</option>\n "; } } ?> <script type="text/javascript"> document.getElementById('Region').value = <?php echo json_encode(trim($_POST['Region']));?>; </script> </select> On my next project that I'm working on now, I need to do the same thing, so I copied the above code amended, and placed in my new project: <select name="Sales_Exec" id="Sales_Exec"> <option value="">-- Select SE --</option> <?php $salesexec=$POST['Sales_Exec']; if ($salesexec); { $salesexecquery = "SELECT DISTINCT Assigned FROM Data "; $salesexecresult = mysql_query($salesexecquery); while($row = mysql_fetch_array($salesexecresult)) { echo "<option value=\"".$row['ASSIGNED']."\">".$row['ASSIGNED']."</option>\n "; } } ?> <script type="text/javascript"> document.getElementById('Sales_Exec').value = <?php echo json_encode(trim($_POST['Sales_Exec']));?>; </script> </select> This second chunk of code doesn't work... and I can't work out why as it seems I've copied it all and amended all the neccersary parts, can anyone spot what is wrong? Thankyou!

  • Linking a Text Box to a variable?

    - by cam
    I would like to have direct access to the text inside a textbox on another form, so I added a public variable _txt to a form and added an event like so: private void richTextBox1_TextChanged(object sender, EventArgs e) { _txt = richTextBox1.Text; } But the form is loaded like this: public FrmTextChild(string text) { InitializeComponent(); _txt = text; richTextBox1.Text = _txt; Text = "Untitled.txt"; } Is there a better way to directly link the two?

  • Creating folders and uploading a file without using a web browser

    - by Ashpak
    I am using the Java Api We have a web application wherein we want our file to be uploaded on an on_click even on some submit button. We don't want the browser to prompt us to enter the username and password to get the access token. Instead, we can provide the username and the password through the code so that we get the access token and the file will be uploaded directly. Right now, OAuth 2 requires that we enter the username and password to be entered through the browser. Reading through the post, I see that we can authenticate for the first time, obtain a refresh token and then keep on refreshing that token periodically. But our application requirements does not allow for this work-flow. Is there any way to automate the process of entering the user credentials using Java code. or Is there any library that will keep the browser away from the process.

  • Create MVC 5 Combo Box from CRM Entities?

    - by SpaceCowboy74
    I am working on an MVC 5 App that pulls data from Dynamics CRM 5. The Data I am getting back is an IQueryable of type Account (The CRM Entity class auto generated by CrmSvcUtil). I am retrieving all of the items and can loop through them with code like this: @foreach (var item in Model.ToList()) { <tr> <td> @item.AccountId </td> <td> @Html.DisplayFor(modelItem => item.Name) </td> </tr> } The problem is, I would like to instead put them in a drop down list. I can't figure out what the syntax is to put these in a DropDown is. Any suggestions?

  • What resources are there for creating a dedicated NES emulator box?

    - by normalocity
    Where do I start, and what communities should I get involved in, in order to achieve the following? Ideally, I'd like to have a box that does the following (doesn't have to do this out of the box, I'm just looking to be able to achieve these goals through configs and necessary dependencies): Either bypasses login, or auto login Auto-start FCEUX with options that will (a) automatically start a ROM of my choosing, and (b) go into full-screen mode. You can assume that before I get that far, I've already configured the input devices and video options. I'd like to create (or install, if it exists) a full-screen app that takes a list of ROMs, allows me to select one with a gamepad/arcade stick, and press a button to open that game Be able to map a button on a gamepad/arcade stick to the "Power off" or exit function of the emulator, such that it will take me back to the ROM selection screen. I've already successfully installed FCEUX and tested it with an arcade stick I own, so I'm not looking for an emulator installer guide. I don't know if the ROM selector app exists already, but I'm a Java developer, and could probably create one (so long as it's not too difficult to support controllers - I was thinking of using Slick2D for this - a gaming library that I'm already pretty familiar with). The goal would be a dedicated box that I have connected to my TV. I power it on. It boots up and starts the ROM selection app, which passes the proper parameters to FCEUX (or another emulator that I might switch to at a later time), and I'm ready to go. Basically an NES emulator as a real, living room console. Also, as far as mapping a controller button to functions in the app, well, I've also played around with hardware, and it would be pretty trivial for me to modify a gamepad to trigger key presses. I just don't want to go to that length if it's not necessary.

  • Is there any automatic tool to remove edges from an image that has been anti-aliased onto a white ba

    - by Macha
    I have a few images that have been anti-aliased onto a white background that I want to put on a transparent background. Just selecting it with the -wand tool/fuzzy select tool/select your terminology of choice- and deleting the background tends to leave a ring of off-white pixels around the image, or eat into the image depending on the tolerance setting. Is there some better way to do this, preferably an automatic tool? (I'm on Linux)

  • Can the XP 'Computer Locked' dialog box be customized?

    - by sadmicrowave
    I'd like to customize the 'computer locked' dialog box in XP to be more graphic oriented, is there any way to do this, or perhaps just change the colors of the box? Also, I'm running dual monitors and would like the box to be positioned in the center of the two screens rather than in the center of Monitor 1 (main). Can this be done?

  • Tiny linux box with 2xGbLAN, WLAN and 10MB/s AES throughput?

    - by Nakedible
    I'd like to find a small linux box with the following specifications: Small (mini-ITX size is OK) Fanless Runs Debian At least two gigabit network interfaces WLAN that supports "host ap" with hostapd + mac80211 in AP mode Can encrypt AES at least 10 megabytes per second Total cost $300 or less Solutions from multiple parts also accepted - I can buy an external network card etc. and build the box myself if the components are available. If you don't know about the "host ap" thing, just suggest your solution, I'll find out if I can get that resolved. If I can't get all that, I can possibly skip the "runs Debian" part, and I can definitely skip the hostapd part if the box can be a wireless access point with multiple ESSIDs out of the box. Something like Asus RT-N16 is close - doesn't run Debian easily, and probably doesn't encrypt AES fast enough. Something like Zotac ZBOX HD-ID11 is also close - no idea which WLAN card it has and it lacks second gigabit interface, but otherwise nice.

  • Need help with a complex 3d scene (using Ogre and bullet)

    - by Matthias
    In my setup there is a box with a hole on one side, and a freely movable "stick" (or bar, tube). This stick can be inserted/moved through the hole into the box. This hole is exactly as wide as the diameter of the stick. In reality, when you would now hold the end of the stick in your hand and move the hand left/right or up/down, the other end of the stick, which is inside the box, would move into the opposite direction of your hand movement (because the stick is affixed at the pivot point where it is entering the box through the hole). (I hope you understand what I mean so far.) Now I need to simulate such a setup in a 3d program. I have already successfully developed an Ogre3d framework for this application, including bullet. But what I don't know is how I can implement in my program what I have described above. This application must include two more features: The scene camera is attached to the end of the stick that is inserted into the box. So when the user would move the mouse (to control "his" end of the stick outside the box), then the camera attached to the stick would move in the opposite direction, as described above. The stick has some length, and the user can push it further into the box, or pull it closer to him again. That means of course that the max. radius on which the end of the stick inside the box can move depends on how far the stick is pushed into the box. Thus, the more the stick is pushed into the box, the larger the max. radius of this end of the stick with the camera will be. I understand this is maybe quite a complex thing, so I don't expect any real source code here. I already have the Ogre and bullet part as said up and running, as well as a camera attached to the stick. This works fine. What I don't know though is how I can simulate the setup described above. Especially the requirement that the stick is affixed at the position of the hole on the box, where it is inserted into the box. Any ideas how I could approach to implement the described setup?

  • How do I cap rendering of tiles in a 2D game with SDL?

    - by farmdve
    I have some boilerplate code working, I basically have a tile based map composed of just 3 colors, and some walls and render with SDL. The tiles are in a bmp file, but each tile inside it corresponds to an internal number of the type of tile(color, or wall). I have pretty basic collision detection and it works, I can also detetc continuous presses, which allows me to move pretty much anywhere I want. I also have a moving camera, which follows the object. The problem is that, the tile based map is bigger than the resolution, thus not all of the map can be displayed on the screen, but it's still rendered. I would like to cap it, but since this is new to me, I pretty much have no idea. Although I cannot post all the code, as even though I am a newbie and the code pretty basic, it's already quite a few lines, I can post what I tried to do void set_camera() { //Center the camera over the dot camera.x = ( player.box.x + DOT_WIDTH / 2 ) - SCREEN_WIDTH / 2; camera.y = ( player.box.y + DOT_HEIGHT / 2 ) - SCREEN_HEIGHT / 2; //Keep the camera in bounds. if(camera.x < 0 ) { camera.x = 0; } if(camera.y < 0 ) { camera.y = 0; } if(camera.x > LEVEL_WIDTH - camera.w ) { camera.x = LEVEL_WIDTH - camera.w; } if(camera.y > LEVEL_HEIGHT - camera.h ) { camera.y = LEVEL_HEIGHT - camera.h; } } set_camera() is the function which calculates the camera position based on the player's positions. I won't pretend I know much about it. Rectangle box = {0,0,0,0}; for(int t = 0; t < TOTAL_TILES; t++) { if(box.x < (camera.x - TILE_WIDTH) || box.y > (camera.y - TILE_HEIGHT)) apply_surface(box.x - camera.x, box.y - camera.y, surface, screen, &clips[tiles[t]]); box.x += TILE_WIDTH; //If we've gone too far if(box.x >= LEVEL_WIDTH) { //Move back box.x = 0; //Move to the next row box.y += TILE_HEIGHT; } } This is basically my render code. The for loop loops over 192 tiles stored in an int array, each with their own unique value describing the tile type(wall or one of three possible colored tiles). box is an SDL_Rect containing the current position of the tile, which is calculated on render. TILE_HEIGHT and TILE_WIDTH are of value 80. So the cap is determined by if(box.x < (camera.x - TILE_WIDTH) || box.y > (camera.y - TILE_HEIGHT)) However, this is just me playing with the values and see what doesn't break it. I pretty much have no idea how to calculate it. My screen resolution is 1024/768, and the tile map is of size 1280/960.
