  • Using Effect For Fog of War

    - by Qua
    I'm trying to apply fog of war to areas on the screen not currently visible to the player. I do this by rendering the game content in one RenderTarget and the the fog of war into another, and then I merge them with an effect file that takes the color from the game RenderTarget and the alpha from the fog of war render target. The FOW RenderTarget is black where the FOW appears, and white where it doesn't. This does work, but it colors the fog of war (the unrevealed locations) white instead of the intended color of black. Before applying the effect I clear the backbuffer of the device to white. When I try to clear it to black, non of the fog of war appears at all, which I assume is a product of alpha blending with black. It works for all other colors, however - giving the resulting screen a tint of that color. How do I archieve a black fog while still being able to do alpha blending between the two render targets? The rendering code for applying the FOW: private RenderTarget2D mainTarget; private RenderTarget2D lightTarget; private void CombineRenderTargetsAndDraw() { batch.GraphicsDevice.SetRenderTarget(null); batch.GraphicsDevice.Clear(Color.White); fogOfWar.Parameters["LightsTexture"].SetValue(lightTarget); batch.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend); fogOfWar.CurrentTechnique.Passes[0].Apply(); batch.Draw( mainTarget, new Rectangle(0, 0, batch.GraphicsDevice.PresentationParameters.BackBufferWidth, batch.GraphicsDevice.PresentationParameters.BackBufferHeight), Color.White ); batch.End(); } The effect file I'm using to apply the FOW: texture LightsTexture; sampler ColorSampler : register(s0); sampler LightsSampler = sampler_state{ Texture = <LightsTexture>; }; struct VertexShaderOutput { float4 Position : POSITION0; float2 TexCoord : TEXCOORD0; }; float4 PixelShaderFunction(VertexShaderOutput input) : COLOR0 { float2 tex = input.TexCoord; float4 color = tex2D(ColorSampler, tex); float4 alpha = tex2D(LightsSampler, tex); return float4(color.r, color.g, color.b, alpha.r); } technique Technique1 { pass Pass1 { PixelShader = compile ps_2_0 PixelShaderFunction(); } }

  • WPF ComboBox in Grid Issue

    - by Nathan
    I am trying to put a series of comboboxes in a grid and then I bind them to a list. For some reason unknown to me when I click the open button on the combobox nothing happens. If I move a comobobox outside the grid it opens just fine. Can someone please tell me what I am doing wrong here. It has to be something stupid because I've used comoboxes before just fine. Here is my xaml: <Grid> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <GroupBox Header="Download Critera" Margin="70,30" Name="groupBox1" Grid.RowSpan="2"> <Grid Height="Auto" Name="grid1" Width="Auto" Margin="0" IsHitTestVisible="False"> <Grid.RowDefinitions> <RowDefinition /> <RowDefinition /> <RowDefinition /> <RowDefinition /> <RowDefinition /> <RowDefinition /> <RowDefinition /> <RowDefinition /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <TextBlock Grid.Row="1" Margin="10,5,5,5" Name="textBlock1" Text="A:" Foreground="Black" VerticalAlignment="Center" FontSize="14" FontWeight="Bold" /> <TextBlock Grid.Row="2" Margin="10,5,5,5" Name="textBlock2" Text="B:" Foreground="Black" VerticalAlignment="Center" FontWeight="Bold" /> <TextBlock Grid.Row="3" Margin="10,5,5,5" Name="textBlock3" Text="C:" Foreground="Black" VerticalAlignment="Center" FontWeight="Bold" /> <TextBlock Grid.Row="4" Margin="10,5,5,5" Name="textBlock4" Foreground="Black" Text="D:" VerticalAlignment="Center" FontWeight="Bold" /> <TextBlock Grid.Row="5" Margin="10,5,5,5" Name="textBlock5" Text="E:" Foreground="Black" TextAlignment="Left" VerticalAlignment="Center" FontWeight="Bold" /> <ComboBox x:Name="cb1" Grid.Column="1" Grid.Row="1" Margin="5" MaxDropDownHeight="100" ItemsSource="{Binding Projects}"/> <ComboBox x:Name="cb2" Grid.Column="1" Grid.Row="2" Margin="5" MaxDropDownHeight="100" ItemsSource="{Binding Projects}"/> <ComboBox x:Name="cb3" Grid.Column="1" Grid.Row="3" Margin="5" MaxDropDownHeight="100" ItemsSource="{Binding Projects}"/> <ComboBox x:Name="cb4" Grid.Column="1" Grid.Row="4" Margin="5" MaxDropDownHeight="100" ItemsSource="{Binding Projects}"/> <ComboBox x:Name="cb5" Grid.Column="1" Grid.Row="5" Margin="5" MaxDropDownHeight="100" ItemsSource="{Binding Projects}"/> </Grid> </GroupBox> </Grid>

  • How to mix textures in DirectX?

    - by tobsen
    I am new to DirectX development and I am wondering if I am taking the wrong route to achieve the following: I would like to mix three textures which contain transparent areas and some solid areas (Red, Blue, Green). The three textures should blend like shown in this example: How can I achieve that in DirectX (preferably in directx9)? A link or example code would be nice. Update: My rendering method looks like this and I still think I am doing it wrong, because the sprite only shows the last texture (nothing is rendered transparent or blended): void D3DTester::render() { d3ddevice->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0,0,0), 1.0f, 0); d3ddevice->BeginScene(); d3ddevice->SetRenderState(D3DRS_ALPHABLENDENABLE, TRUE); d3ddevice->SetRenderState(D3DRS_SRCBLEND, D3DBLEND_ONE); d3ddevice->SetRenderState(D3DRS_DESTBLEND, D3DBLEND_ONE); LPD3DXSPRITE sprite=NULL; HRESULT hres = D3DXCreateSprite(d3ddevice, &sprite); if(hres != S_OK) { throw std::exception(); } sprite->Begin(D3DXSPRITE_ALPHABLEND); std::vector<LPDIRECT3DTEXTURE9>::iterator it; for ( it=textures.begin() ; it < textures.end(); it++ ) { sprite->Draw(*it, NULL, NULL, NULL, 0xFFFFFFFF); } sprite->End(); d3ddevice->EndScene(); d3ddevice->Present(NULL, NULL, NULL, NULL); } The resulting image looks like this: But I need it to look like this instead: Update2: I figured out that I have to SetRenderState after I use sprite->Begin(D3DXSPRITE_ALPHABLEND); thanks to the hint by Josh Petrie. However, by using this: sprite->Begin(D3DXSPRITE_ALPHABLEND); d3ddevice->SetRenderState(D3DRS_ALPHABLENDENABLE, TRUE); d3ddevice->SetRenderState(D3DRS_SRCBLEND, D3DBLEND_ONE); d3ddevice->SetRenderState(D3DRS_DESTBLEND, D3DBLEND_ONE); std::vector<LPDIRECT3DTEXTURE9>::iterator it; for ( it=textures.begin() ; it < textures.end(); it++ ) { sprite->Draw(*it, NULL, NULL, NULL, 0xFFFFFFFF); } sprite->End(); The sprites colors are becoming transparent towards the background scene e.g.: if I use d3ddevice->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0,100,21), 1.0f, 0); the result looks like: Is there any way to avoid that? I would like the sprites be transparent to each other but to be still solid to the background. Update3: After having sombody explained to me, how to do what @LaurentCouvidou and @JoshPetrie suggested, I have a working solution and therfore accept the answer: d3ddevice->BeginScene(); D3DCOLOR white = D3DCOLOR_RGBA((UINT)255, (UINT)255, (UINT)255, 255); D3DCOLOR black = D3DCOLOR_RGBA((UINT)0, (UINT)0, (UINT)0, 255); sprite->Begin(D3DXSPRITE_ALPHABLEND); sprite->Draw(pTextureRed, NULL, NULL, NULL, black); sprite->Draw(pTextureGreen, NULL, NULL, NULL, black); sprite->Draw(pTextureBlue, NULL, NULL, NULL, black); sprite->End(); sprite->Begin(D3DXSPRITE_ALPHABLEND); d3ddevice->SetRenderState(D3DRS_ALPHATESTENABLE, TRUE); d3ddevice->SetRenderState(D3DRS_BLENDOP, D3DBLENDOP_ADD); d3ddevice->SetRenderState(D3DRS_SRCBLEND, D3DBLEND_ONE); d3ddevice->SetRenderState(D3DRS_DESTBLEND, D3DBLEND_ONE); sprite->Draw(pTextureRed, NULL, NULL, NULL, white); sprite->Draw(pTextureGreen, NULL, NULL, NULL, white); sprite->Draw(pTextureBlue, NULL, NULL, NULL, white); sprite->End(); d3ddevice->EndScene(); d3ddevice->Present(NULL, NULL, NULL, NULL);

  • Why won't my code work in Ubuntu Server 11.10? Is it because of gd library?

  • Set UIViewController background to transparent

    - by dbonneville
    I'm calling a UIViewController from a button on the main view. I have set the alpha of the view to 50%. When the view animates in, I can see that it's transparent. As soon as the animation stops, it becomes opaque. In the xib, when I set opacity, it's sets the opacity over white. So if I set the color to black and the opacity to 50%, this is what I see when I click the button on the main interface to show the view: view slides up from bottom at 50% opacity. I can see the underlaying view through the transparent black nicely. when view stops animating, it become gray. it appears that a white color pops in the background of the view somehow, making the 50% opacity black over white turn gray. I can no longer see the underlaying layer. What I'm trying to do: show 100% white text on a 50% transparent black layer which sits over the view that called this view. How on earth do I do this? I tried a code method that sets the background color when the view is called, but it does exactly the same thing (with another try in there commented out with the same effect): - (IBAction)gotoCreed { Creed *creed = [[Creed alloc] initWithNibName:nil bundle:nil]; [self presentModalViewController:creed animated:YES]; self.view.backgroundColor = [UIColor colorWithHue:0.0 saturation:0.0 brightness:1.0 alpha:0.2]; //self.view.backgroundColor = [UIColor clearColor]; }

  • SQL Joining on a one-to-many relationship

    - by Harley
    Ok, here was my original question; Table one contains ID|Name 1 Mary 2 John Table two contains ID|Color 1 Red 1 Blue 2 Blue 2 Green 2 Black I want to end up with is ID|Name|Red|Blue|Green|Black 1 Mary Y Y 2 John Y Y Y It seems that because there are 11 unique values for color and 1000's upon 1000's of records in table one that there is no 'good' way to do this. So, two other questions. Is there an efficient way to query to get this result? I can then create a crosstab in my application to get the desired result. ID|Name|Color 1 Mary Red 1 Mary Blue 2 John Blue 2 John Green 2 John Black If I wanted to limit the number of records returned how could I do a query to do something like this? Where ((color='blue') AND (color<>'red' OR color<>'green')) So using the above example I would then get back ID|Name|Color 1 Mary Blue 2 John Blue 2 John Black I connect to Visual FoxPro tables via ADODB to use SQL. Thanks!

  • Item rendered via a DataTemplate with any Background Brush renders selection coloring behind item.

    - by Mike L
    I have a ListBox which uses a DataTemplate to render databound items. The XAML for the datatemplate is as follows: <DataTemplate x:Key="NameResultTemplate"> <WrapPanel x:Name="PersonResultWrapper" Margin="0" Orientation="Vertical" Background="{Binding Converter={StaticResource NameResultToColor}, Mode=OneWay}" > <i:Interaction.Triggers> <i:EventTrigger EventName="MouseDown"> <cmd:EventToCommand x:Name="SelectPersonEventCommand" Command="{Binding Search.SelectedPersonCommand, Mode=OneWay, Source={StaticResource Locator}}" CommandParameter="{Binding Mode=OneWay}" /> </i:EventTrigger> </i:Interaction.Triggers> <TextBlock x:Name="txtPersonName" TextWrapping="Wrap" Margin="0" VerticalAlignment="Top" Text="{Binding PersonName}" FontSize="24" Foreground="Black" /> <TextBlock x:Name="txtAgencyName" TextWrapping="Wrap" Text="{Binding AgencyName}" HorizontalAlignment="Left" VerticalAlignment="Bottom" Margin="0" FontStyle="Italic" Foreground="Black" /> <TextBlock x:Name="txtPIDORI" TextWrapping="Wrap" Text="{Binding PIDORI}" HorizontalAlignment="Left" VerticalAlignment="Bottom" Margin="0" FontStyle="Italic" Foreground="Black" /> <TextBlock x:Name="txtDescriptors" TextWrapping="Wrap" Text="{Binding DisplayDescriptors}" Margin="0" VerticalAlignment="Top" Foreground="Black"/> <Separator Margin="0" Width="400" /> </WrapPanel> </DataTemplate> Note that there is a value converter called NameResultToColor which changes the background brush of the rendered WrapPanel to gradient brush depending on certain scenarios. All of this works as I'd expect, except when you click on any of the rendered ListBox items. When you click one, there is only the slightest sign of the selection coloring (the default bluish color). I can see a trace bit of it underneath my gradient-brushed item. If I reset the background brush to "no brush" then the selection rendering works properly. If I set the background brush to a solid color, it also fails to render as I'd expect. How can I get the selection coloring to be on top? What is trumping the selection rendering?

  • I need some help cropping an image in PHP (GD)

    - by evan
    http://i.imgur.com/foT9u.jpg Using that image as an example, here's what I need to do: Crop the blue square to have the same proportional ratio as that of the black square From doing that, I should then be able to resize the blue square to fit into the black square without losing stretching it - It'll retain its proportions. Note: The blue square must be cropped 'from the center'. The original center should remain the center after the crop (it can't be cropped from the top left, for example). Here's what I'm thinking needs to be done (using the, landscape, blue square as the example): Figure out the difference between the black squares width and height Figure out the difference between the blue squares width and height This should tell me how much to crop the blue square by and with how much of a 'top offset' Once it's cropped to fit the black squares proportions, it can then be resized I've been messing around with code similar to: if (BLACK_WIDTH > BLACK_HEIGHT) { $diffHeight = BLACK_WIDTH - BLACK_HEIGHT; $newHeight = $blue_Height - $blue_Height; echo $newHeight; } And using Photoshop to try and get a feel for how this should be done, but it continues to fail .< How should I go about doing this? How can I figure out how much to crop by (depending on if the blue square is landscape or portrait)? How do I then get the offset to retain the blue squares center?

    I'm drawing a circle in C# and i have divided it into some parts,i want to fill different parts with different colors,is there anyway to do this? and how?i tried using fillpie() but i couldn't get the arguments to work. here is the code: int r = 150; g.DrawEllipse(Pens.Black, 300 - r, 250 - r, 2 * r, 2 * r); if (p != 0) g.DrawLine(Pens.Black, 300, 250, 300 + r, 250); double sum; sum = 0.0; for (int j = 0; j < p; j++) sum += data[j].value; double angle; angle = 0.0; for (int i = 0; i < p; i++) { angle += (double)(data[i].value / sum) * 2.0 * Math.PI; textBox1.Text += sum.ToString() + " : " + angle.ToString() + ":" + Math.Cos(angle).ToString() + "\r\n"; g.DrawLine(Pens.Black, 300, 250, 300 + (int)(Math.Cos(angle) * r), 250 - (int)(Math.Sin(angle) * r)); //g.FillPie(Brushes.Black, 300-r , 250 - r, r, r ,(float)(angle),(float)(angle+ (data[i].value / sum) * 2.0 * Math.PI)); } this actually divides the circle into different parts,i don't know how to fill them the commented line is where i

  • How do I get rid of the space between <img> elements in a row in a html page?

    - by Aperture
    I'm displaying 3 <img> in a row like this: <div style="width: 950px"> <img src='/UploadedImages/86.jpg' alt='' style="width: 300px; margin: 0px; padding: 0px; border: 1px solid Black" /> <img src='/UploadedImages/85.jpg' alt='' style="width: 300px; margin: 0px; padding: 0px; border: 1px solid Black" /> <img src='/UploadedImages/84.gif' alt='' style="width: 300px; margin: 0px; padding: 0px; border: 1px solid Black" /> </div> As you can see I have thin black borders around the images. My problem is that there are white spaces about 5px wide between the borders of neighbouring images and I have set the margin to be 0px but it does not work. So what is happening here?

  • filling colors on a map - PHP

    - by jeremy
    I am trying to determine how to fill colors onto a map - such as the "Risk" board game map. I've done this before with HTML tables, by pulling an HTML color code from a SQL table and then just using it to fill the cell the color I want it. But for a non-square map, I'm not sure where to look. I have created a very simple two color map - its white with black borders. My desired result is having the 'regions' on the map shaded with a color, based on data in a sql table (just like the "fill" button in Paint). This looks like what I need: http://php.net/manual/en/function.imagefilltoborder.php and now.. how to define the borders... At the moment I have tried nothing, because the question was: how do I have PHP fill parts of an image? I have tried making an image in Paint, and then scratching my head wondering how to fill parts of it. Having stumbled upon a link, let me focus this a bit more: It appears that with imagefilltoborder that I can put an image on my server, perhaps one that looks like a black and white version of the RISK map - black borders and white everything else. Some questions: Is it correct that the 'border' variable should use the color of my border (whatever value black is) so that the code can "see" where the border is? Is it correct that I'll just need to figure out X,Y coords to begin the fill? Does this work if I have 10 different spots to fill on the map? Can I use varying colors from code or pulled from SQL to assign different colors to those 10 spots, and use 10 different X,Y coords to get them all?

  • How can I define an irregular area of the screen and find the closest point to the mouse in that area?

    - by JonathonG
    I'm looking for a method to define an area of the screen that the mouse cannot leave. I have been directed by rob mayoff, the answerer of this question, that I can use a Quartz Event Tap to detect mouse events. This puts me part of the way to the solution to THIS question. I need to define an irregular area of the screen, not just a rectangle, that the mouse cannot leave. I have been researching this and the only idea I can come up with is using a bitmap to define the irregular area, as it will be very oddly shaped. However, I am open to solutions other than using a bitmap. Since this must be done on a Mac, I've determined that I will have to use objective C / Cocoa . I need to know how to define the area and, equally importantly, how to find the closest point in the area to the mouse (so that I can move the mouse to it if the mouse tries to move outside of the area). This is similar to what the restricted area will look like: [edit:] Okay, I've come up with part of the answer to this. If I can do a basic (light-weight) point collision detection on the image mask, I can use a simple algorithm to detect the closest point to the mouse on the black area of the image. I could do this by calculating distance between a pre-defined point (P) inside the black area of the image and the target mouse position (T), taking the midpoint (M), then checking if the midpoint is inside or outside of the shape (black or white, respectively). If M is inside the shape, then move the P to M, otherwise move T to the M, continuously recalculate this until the distance between T and P is 1 pixel or less, then move the mouse to the final calculated position. All of that being said, I still need some way to test the position of the mouse against that same position on the bitmap (assume the bitmap is the same resolution as the monitor), and check if that point is black or white. All of this needs to be done in the background, without this application actually having focus, or the bitmap being visible... is this possible?

  • yet another logic.

    - by Sunil
    I'm working on a research problem out of curiosity and I don't know how to program the logic that I've in mind. Let me explain it to you : I've 4 vectors say for example, v1 = 1 1 1 1 v2 = 2 2 2 2 v3 = 3 3 3 3 v4 = 4 4 4 4 Now what I want to do is to add them combination-wise. i.e v12 = v1+v2 v13 = v1+v3 v14 = v1+v4 v23 = v2+v3 v24 = v2+v4 v34 = v3+v4 Till this step it is just fine. The problem/trick is now, at the end of each iteration I give the obtained vectors into a black box function and it returns only few of the vectors say v12, v13 and v34. Now, I want to add each of these vectors one vector from v1,v2,v3,v4 which it hasn't added before. For example v3 and v4 hasn't been added to v12 so I want to create v123 and v124. similarly for all the vectors like, v12 should become : v123 = v12+v3 v124 = v12+v4 v13 should become : v132 // this should not occur because I already have v123 v134 = v13+v4; v14,v23 and v24 cannot be considered because it was deleted in the black box function so all we have in our hands to work with is v12,v13 and v34. v34 should become : v341 // cannot occur because we have 134 v342 = v34+v2 It is important that I do not do all at one step at the start like for example I can do (4 choose 3) 4C3 and finish it off but I want to do it step by step at each iteration. I've asked a modified version of this question before (without including the black box function) and got answers here. Can anybody tell me how to do it when the black box function is included ? A modification of the previous answer would also be great. Thanks in advance.

  • Applications: How to create a custom dialog box for Windows Mobile 6 (native)

    - by TechTwaddle
    Ashraf, on the MSDN forum, asks, “Is there a way to make a default choice for the messagebox that happens after a period of time if the user doesn't choose (Clicked ) Yes or No buttons.” To elaborate, the requirement is to show a message box to the user with certain options to select, and if the user does not respond within a predefined time limit (say 8 seconds) then the message box must dismiss itself and select a default option. Now such a functionality is not available with the MessageBox() api, you will have to write your own custom dialog box. Surely, creating a dialog box is quite a simple task using the DialogBox() api, and we have been creating full screen dialog boxes all the while. So how will this custom message box be any different? It’s not much different from a regular dialog box except for a few changes in its properties. First, it has a title bar but no buttons on the title bar (no ‘x’ or ‘ok’ button on the title bar), it doesn’t occupy full screen and it contains the controls that you put into it, thus justifying the title ‘custom’. So in this post we create a custom dialog box with two buttons, ‘Black’ and ‘White’. The user is given 8 seconds to select one of those colours, if the user doesn’t make a selection in 8 seconds, the default option ‘Black’ is selected. Before going into the implementation here is a video of how the dialog box works; Custom dialog box To start off, add a new dialog resource into your application, size it appropriately and add whatever controls you need to the dialog. In my case, I added two static text labels and two buttons, as below; Now we need to write up the window procedure for this dialog, here is the complete function; BOOL CALLBACK CustomDialogProc(HWND hDlg, UINT uMessage, WPARAM wParam, LPARAM lParam) {     int wmID, wmEvent;     PAINTSTRUCT ps;     HDC hdc;     static int timeCount = 0;     switch(uMessage)     {         case WM_INITDIALOG:             {                 SHINITDLGINFO shidi;                 memset(&shidi, 0, sizeof(shidi));                 shidi.dwMask = SHIDIM_FLAGS;                 //shidi.dwFlags = SHIDIF_DONEBUTTON | SHIDIF_SIPDOWN | SHIDIF_SIZEDLGFULLSCREEN | SHIDIF_EMPTYMENU;                 shidi.dwFlags = SHIDIF_SIPDOWN | SHIDIF_EMPTYMENU;                 shidi.hDlg = hDlg;                 SHInitDialog(&shidi);                 SHDoneButton(hDlg, SHDB_HIDE);                 timeCount = 0;                 SetWindowText(GetDlgItem(hDlg, IDC_STATIC_TIME_REMAINING), L"Time remaining: 8 second(s)");                 SetTimer(hDlg, MY_TIMER, 1000, NULL);             }             return TRUE;         case WM_COMMAND:             {                 wmID = LOWORD(wParam);                 wmEvent = HIWORD(wParam);                 switch(wmID)                 {                     case IDC_BUTTON_BLACK:                         KillTimer(hDlg, MY_TIMER);                         EndDialog(hDlg, IDC_BUTTON_BLACK);                         break;                     case IDC_BUTTON_WHITE:                         KillTimer(hDlg, MY_TIMER);                         EndDialog(hDlg, IDC_BUTTON_WHITE);                         break;                 }             }             break;         case WM_TIMER:             {                 if (wParam == MY_TIMER)                 {                     WCHAR wszText[128];                     memset(&wszText, 0, sizeof(wszText));                     timeCount++;                     //8 seconds are over, dismiss the dialog, select def value                     if (timeCount >= 8)                     {                         KillTimer(hDlg, MY_TIMER);                         EndDialog(hDlg, IDC_BUTTON_BLACK_DEF);                     }                     wsprintf(wszText, L"Time remaining: %d second(s)", 8-timeCount);                     SetWindowText(GetDlgItem(hDlg, IDC_STATIC_TIME_REMAINING), wszText);                     UpdateWindow(GetDlgItem(hDlg, IDC_STATIC_TIME_REMAINING));                 }             }             break;         case WM_PAINT:             {                 hdc = BeginPaint(hDlg, &ps);                 EndPaint(hDlg, &ps);             }             break;     }     return FALSE; } The MSDN documentation mentions that you need to specify the flag WS_NONAVDONEBUTTON, but I got an error saying that the value could not be found, so we can ignore this for now. Next up, while calling SHInitDialog() for your custom dialog, make sure that you don’t specify SHDIF_DONEBUTTON in the dwFlags member of the SHINITDIALOG structure, this member makes the ‘ok’ button appear on the dialog title bar. Finally, we need to call SHDoneButton() with SHDB_HIDE flag to, well, hide the Done button. The ‘Done’ button is the same as the ‘ok’ button, so this step might seem redundant, and the dialog works fine without calling SHDoneButton() too, but it’s better to stick with the documentation (; So you can see that we have followed all these steps above, under WM_INITDIALOG. We also setup a few things like a variable to keep track of the time, and setting off a one second timer. Every time the timer fires, we receive a WM_TIMER message. We then update the static label displaying the amount of time left to the user. If 8 seconds go by without the user selecting any option, we kill the timer and end the dialog with IDC_BUTTON_BLACK_DEF. This is just a #define’d integer value, make sure it’s unique. You’ll see why this is important. If the user makes a selection, either Black or White, we kill the timer and end the dialog with corresponding selection the user made, that is, either IDC_BUTTON_BLACK or IDC_BUTTON_WHITE. Ok, so now our custom dialog is ready to be used. I invoke the custom dialog from a menu entry in the main windows as below, case IDM_MENU_CUSTOMDLG:     {         int ret = DialogBox(g_hInst, MAKEINTRESOURCE(IDD_CUSTOM_DIALOG), hWnd, CustomDialogProc);         switch(ret)         {             case IDC_BUTTON_BLACK_DEF:                 SetWindowText(g_hStaticSelection, L"You Selected: Black (default)");                 break;             case IDC_BUTTON_BLACK:                 SetWindowText(g_hStaticSelection, L"You Selected: Black");                 break;             case IDC_BUTTON_WHITE:                 SetWindowText(g_hStaticSelection, L"You Selected: White");                 break;         }         UpdateWindow(g_hStaticSelection);     }     break; So you see why ending the dialog with the corresponding value was important, that’s what the DialogBox() api returns with. And in the main window I update a static text label to show which option was selected. I cranked this out in about an hour, and unfortunately don’t have time for a managed C# version. That will have to be another post, if I manage to get it working that is (;

  • Export to csv, string w/ comma in it, splits it up

From what I've read so far the Epson Stylus C84 won't print like this because it uses a little bit of color in even when you print only in black to prevent the ink heads from drying out. Is there ANY way that I can bypass this?
