• Masking OpenGL texture by a pattern

  - by user1304844

  Tiled terrain. User wants to build a structure. He presses build and for each tile there is an "allow" or "disallow" tile sprite added to the scene. FPS drops right away, since there are 600+ tiles added to the screen. Since map equals screen, there is no scrolling. I came to an idea to make an allow grid covering the whole map and mask the disallow fields. Approach 1: Create allow and disallow grid textures. Draw a polygon on screen. Pass both textures to the fragment shader. Determine the position inside the polygon and use color from allowTexture if the fragment belongs to the allow field, disallow otherwise Problem: How do I know if I'm on the field that isn't allowed if I cannot pass the matrix representing the map (enum FieldStatus[][] (Allow / Disallow)) to the shader? Therefore, inside the shader I don't know which fragments should be masked. Approach 2: Create allow texture. Create an empty texture buffer same size as the allow texture Memset the pixels of the empty texture to desired color for each pixel that doesn't allow building. Draw a polygon on screen. Pass both textures to the fragment shader. Use texture2 color if alpha 0, texture1 color otherwise. Problem: I'm not sure what is the right way to manipulate pixels on a texture. Do I just make a buffer with width*height*4 size and memcpy the color[] to desired coordinates or is there anything else to it? Would I have to call glTexImage2D after every change to the texture? Another problem with this approach is that it takes a lot more work to get a prettier effect since I'm manipulating the color pixels instead of just masking two textures. varying vec2 TexCoordOut; uniform sampler2D Texture1; uniform sampler2D Texture2; void main(void){ vec4 allowColor = texture2D(Texture1, TexCoordOut); vec4 disallowColor = texture2D(Texture2, TexCoordOut); if(disallowColor.a > 0){ gl_FragColor= disallowColor; }else{ gl_FragColor= allowColor; }} I'm working with OpenGL on Windows. Any other suggestion is welcome.

• Access Control Service v2: Registering Web Identities in your Applications [concepts]

  - by Your DisplayName here!

  ACS v2 support two fundamental types of client identities– I like to call them “enterprise identities” (WS-*) and “web identities” (Google, LiveID, OpenId in general…). I also see two different “mind sets” when it comes to application design using the above identity types: Enterprise identities – often the fact that a client can present a token from a trusted identity provider means he is a legitimate user of the application. Trust relationships and authorization details have been negotiated out of band (often on paper). Web identities – the fact that a user can authenticate with Google et al does not necessarily mean he is a legitimate (or registered) user of an application. Typically additional steps are necessary (like filling out a form, email confirmation etc). Sometimes also a mixture of both approaches exist, for the sake of this post, I will focus on the web identity case. I got a number of questions how to implement the web identity scenario and after some conversations it turns out it is the old authentication vs. authorization problem that gets in the way. Many people use the IsAuthenticated property on IIdentity to make security decisions in their applications (or deny user=”?” in ASP.NET terms). That’s a very natural thing to do, because authentication was done inside the application and we knew exactly when the IsAuthenticated condition is true. Been there, done that. Guilty ;) The fundamental difference between these “old style” apps and federation is, that authentication is not done by the application anymore. It is done by a third party service, and in the case of web identity providers, in services that are not under our control (nor do we have a formal business relationship with these providers). Now the issue is, when you switch to ACS, and someone with a Google account authenticates, indeed IsAuthenticated is true – because that’s what he is! This does not mean, that he is also authorized to use the application. It just proves he was able to authenticate with Google. Now this obviously leads to confusion. How can we solve that? Easy answer: We have to deal with authentication and authorization separately. Job done ;) For many application types I see this general approach: Application uses ACS for authentication (maybe both enterprise and web identities, we focus on web identities but you could easily have a dual approach here) Application offers to authenticate (or sign in) via web identity accounts like LiveID, Google, Facebook etc. Application also maintains a database of its “own” users. Typically you want to store additional information about the user In such an application type it is important to have a unique identifier for your users (think the primary key of your user database). What would that be? Most web identity provider (and all the standard ACS v2 supported ones) emit a NameIdentifier claim. This is a stable ID for the client (scoped to the relying party – more on that later). Furthermore ACS emits a claims identifying the identity provider (like the original issuer concept in WIF). When you combine these two values together, you can be sure to have a unique identifier for the user, e.g.: Facebook-134952459903700\799880347 You can now check on incoming calls, if the user is already registered and if yes, swap the ACS claims with claims coming from your user database. One claims would maybe be a role like “Registered User” which can then be easily used to do authorization checks in the application. The WIF claims authentication manager is a perfect place to do the claims transformation. If the user is not registered, show a register form. Maybe you can use some claims from the identity provider to pre-fill form fields. (see here where I show how to use the Facebook API to fetch additional user properties). After successful registration (which may include other mechanisms like a confirmation email), flip the bit in your database to make the web identity a registered user. This is all very theoretical. In the next post I will show some code and provide a download link for the complete sample. More on NameIdentifier Identity providers “guarantee” that the name identifier for a given user in your application will always be the same. But different applications (in the case of ACS – different ACS namespaces) will see different name identifiers. This is by design to protect the privacy of users because identical name identifiers could be used to create “profiles” of some sort for that user. In technical terms they create the name identifier approximately like this: name identifier = Hash((Provider Internal User ID) + (Relying Party Address)) Why is this important to know? Well – when you change the name of your ACS namespace, the name identifiers will change as well and you will will lose your “connection” to your existing users. Oh an btw – never use any other claims (like email address or name) to form a unique ID – these can often be changed by users.

• GLSL, all in one or many shader programs?

  - by stjepano

  I am doing some 3D demos using OpenGL and I noticed that GLSL is somewhat "limited" (or is it just me?). Anyway I have many different types of materials. Some materials have ambient and diffuse color, some materials have ambient occlusion map, some have specular map and bump map etc. Is it better to support everything in one vertex/fragment shader pair or is it better to create many vertex/fragment shaders and select them based on currently selected material? What is the usual shader strategy in OpenGL or D3D?

• GLSL per pixel lighting with custom light type

  - by Justin

  Ok, I am having a big problem here. I just got into GLSL yesterday, so the code will be terrible, I'm sure. Basically, I am attempting to make a light that can be passed into the fragment shader (for learning purposes). I have four input values: one for the position of the light, one for the color, one for the distance it can travel, and one for the intensity. I want to find the distance between the light and the fragment, then calculate the color from there. The code I have gives me a simply gorgeous ring of light that get's twisted and widened as the matrix is modified. I love the results, but it is not even close to what I am after. I want the light to be moved with all of the vertices, so it is always in the same place in relation to the objects. I can easily take it from there, but getting that to work seems to be impossible with my current structure. Can somebody give me a few pointers (pun not intended)? Vertex shader: attribute vec4 position; attribute vec4 color; attribute vec2 textureCoordinates; varying vec4 colorVarying; varying vec2 texturePosition; varying vec4 fposition; varying vec4 lightPosition; varying float lightDistance; varying float lightIntensity; varying vec4 lightColor; void main() { vec4 ECposition = gl_ModelViewMatrix * gl_Vertex; vec3 tnorm = normalize(vec3 (gl_NormalMatrix * gl_Normal)); fposition = ftransform(); gl_Position = fposition; gl_TexCoord[0] = gl_MultiTexCoord0; fposition = ECposition; lightPosition = vec4(0.0, 0.0, 5.0, 0.0) * gl_ModelViewMatrix * gl_Vertex; lightDistance = 5.0; lightIntensity = 1.0; lightColor = vec4(0.2, 0.2, 0.2, 1.0); } Fragment shader: varying vec4 colorVarying; varying vec2 texturePosition; varying vec4 fposition; varying vec4 lightPosition; varying float lightDistance; varying float lightIntensity; varying vec4 lightColor; uniform sampler2D texture; void main() { float l_distance = sqrt((gl_FragCoord.x * lightPosition.x) + (gl_FragCoord.y * lightPosition.y) + (gl_FragCoord.z * lightPosition.z)); float l_value = lightIntensity / (l_distance / lightDistance); vec4 l_color = vec4(l_value * lightColor.r, l_value * lightColor.g, l_value * lightColor.b, l_value * lightColor.a); vec4 color; color = texture2D(texture, gl_TexCoord[0].st); gl_FragColor = l_color * color; //gl_FragColor = fposition; }

• What is the recommended way to output values to FBO targets? (OpenGL 3.3 + GLSL 330)

  - by datSilencer

  I'll begin by apologizing for any dumb assumptions you might find in the code below since I'm still pretty much green when it comes to OpenGL programming. I'm currently trying to implement deferred shading by using FBO's and their associated targets (textures in my case). I have a simple (I think :P) geometry+fragment shader program and I'd like to write its Fragment Shader stage output to three different render targets (previously bound by a call to glDrawBuffers()), like so: #version 330 in vec3 WorldPos0; in vec2 TexCoord0; in vec3 Normal0; in vec3 Tangent0; layout(location = 0) out vec3 WorldPos; layout(location = 1) out vec3 Diffuse; layout(location = 2) out vec3 Normal; uniform sampler2D gColorMap; uniform sampler2D gNormalMap; vec3 CalcBumpedNormal() { vec3 Normal = normalize(Normal0); vec3 Tangent = normalize(Tangent0); Tangent = normalize(Tangent - dot(Tangent, Normal) * Normal); vec3 Bitangent = cross(Tangent, Normal); vec3 BumpMapNormal = texture(gNormalMap, TexCoord0).xyz; BumpMapNormal = 2 * BumpMapNormal - vec3(1.0, 1.0, -1.0); vec3 NewNormal; mat3 TBN = mat3(Tangent, Bitangent, Normal); NewNormal = TBN * BumpMapNormal; NewNormal = normalize(NewNormal); return NewNormal; } void main() { WorldPos = WorldPos0; Diffuse = texture(gColorMap, TexCoord0).xyz; Normal = CalcBumpedNormal(); } If my render target textures are configured as: RT1:(GL_RGB32F, GL_RGB, GL_FLOAT, GL_TEXTURE0, GL_COLOR_ATTACHMENT0) RT2:(GL_RGB32F, GL_RGB, GL_FLOAT, GL_TEXTURE1, GL_COLOR_ATTACHMENT1) RT3:(GL_RGB32F, GL_RGB, GL_FLOAT, GL_TEXTURE2, GL_COLOR_ATTACHMENT2) And assuming that each texture has an internal format capable of contaning the incoming data, will the fragment shader write the corresponding values to the expected texture targets? On a related note, do the textures need to be bound to the OpenGL context when they are Multiple Render Targets? From some Googling, I think there are two other ways to output to MRTs: 1: Output each component to gl_FragData[n]. Some forum posts say this method is deprecated. However, looking at the latest OpenGL 3.3 and 4.0 specifications at opengl.org, the core profiles still mention this approach. 2: Use a typed output array variable for the expected type. In this case, I think it would be something like this: out vec3 [3] output; void main() { output[0] = WorldPos0; output[1] = texture(gColorMap, TexCoord0).xyz; output[2] = CalcBumpedNormal(); } So which is then the recommended approach? Is there a recommended approach at all if I plan to code on top of OpenGL 3.3? Thanks for your time and help!

• Do I lose/gain performance for discarding pixels even if I don't use depth testing?

  - by Gajoo

  When I first searched for discard instruction, I've found experts saying using discard will result in performance drain. They said discarding pixels will break GPU's ability to use zBuffer properly because GPU have to first run Fragment shader for both objects to check if the one nearer to camera is discarded or not. For a 2D game I'm currently working on, I've disabled both depth-test and depth-write. I'm drawing all objects sorted by their depth and that's all, no need for GPU to do fancy things. now I'm wondering is it still bad if I discard pixels in my fragment shader?

This is absolutely blowing my mind. Can anyone help? (I suspect it has to do with repsep, but I am not sure.) define foo(a) { if (!h(IM) && a(1)) then { return 0; } if (a() && !h()) then { return 0; } } EDIT: Any constructive comments about my Scala style is also appreciated.

place though. At another part of the code the lister seems to be invoked. Though, there are both Controller types and both us $em->persist($something); $em->flush(); to save the changes. I would expect that in both cases the listener is invoked.

• How to set up dual quadro cards on RHEL 5.5?

  - by Alex J. Roberts

  I have a RHEL 5 workstation with 2 nvidia Quadro FX4500 cards, with one display attached to each card. After doing a clean install of RHEL 5.5, the second display doesnt work (it worked ok in RHEL 5.2). Neither separate X screens nor Xinerama are working. The kernel version is 2.6.18-194.el5 I've tried nvidia drivers 185.18.36 (the ones that i was using on 5.2) and the latest 260.19.36 and neither works. My xorg.conf is as follows: # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 1.0 (buildmeister@builder58) Fri Aug 14 18:34:43 PDT 2009 Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" RightOf "Screen0" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "Files" FontPath "unix/:7100" EndSection Section "ServerFlags" Option "Xinerama" "1" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/input/mice" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from data in "/etc/sysconfig/keyboard" Identifier "Keyboard0" Driver "kbd" Option "XkbLayout" "us" Option "XkbModel" "pc105" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor0" VendorName "Unknown" ModelName "DELL 3007WFP" HorizSync 49.3 - 98.5 VertRefresh 60.0 Option "DPMS" EndSection Section "Monitor" # HorizSync source: edid, VertRefresh source: edid Identifier "Monitor1" VendorName "Unknown" ModelName "DELL 3007WFP" HorizSync 49.3 - 98.5 VertRefresh 60.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "Quadro FX 4500" BusID "PCI:10:0:0" EndSection Section "Device" Identifier "Device1" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "Quadro FX 4500" BusID "PCI:129:0:0" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Device1" Monitor "Monitor1" DefaultDepth 24 Option "TwinView" "0" Option "metamodes" "nvidia-auto-select +0+0" SubSection "Display" Depth 24 EndSubSection EndSection And the Xorg Log: X Window System Version 7.1.1 Release Date: 12 May 2006 X Protocol Version 11, Revision 0, Release 7.1.1 Build Operating System: Linux 2.6.18-164.11.1.el5 x86_64 Red Hat, Inc.

• How do I enable greedy MigrationHeuristic in Karmic?

  - by Matthew

  My laptop performs very poorly for 2d graphics. For example, Docky's zoom effect and compiz effects are very choppy. In Jaunty, I was able to fix this by adding the following line under the "Device" section in my xorg.conf: Option "MigrationHeuristic" "greedy" In Karmic, there is no xorg.conf by default, so I copied my old one (from Jaunty). However, everything is still slow. Here is my xorg.conf: Section "Device" Identifier "Configured Video Device" Option "MigrationHeuristic" "greedy" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" EndSection From googling about, it sounds like "MigrationHeuristic" is only an option for the "EXA" mode, while Karmic has switched the intel driver to "UXA". So I tried adding this line under the "Device" section: Option "AccelMethod" "exa" But this didn't help.

• Easiest method of creating multiple Word documents with incremental number?

  - by DakotaDusty

  I need to create about 80 Word documents that are identical except for a numerical identifier in the document. The identifier is the same as the document filename, eg. the document named "SN-100.doc" must have the string "SN-100" inside the document text. Each unique document will reside in a folder location given by its unique numerical identifier.For example, the file directory hierarchy will look something like this: /SN001/SN-1.doc /SN002/SN-2.doc . . . /SN080/SN-80.doc What is the easiest and fastest method of doing this?

• Raid Shows Up as Multiple Drives - Can't Mount

  - by manyxcxi

  I have a single hard drive that the OS is installed on and I have Sil raid card installed with two matching 500GB hdds set up in Raid 0 and formatted- they're completely empty. For whatever reason they are showing up as /dev/sdb and /dev/sdc and not as a single hard drive. I used fdisk to format both raid drives as Linux raid auto (fd) but I cannot mount either device and dmraid doesn't seem to want to work, what step am I missing? When I installed 9.04 oh so long ago it seems like it recognized and automatically did everything that needed to be done, now I'm stuck. dmraid Output root@tripoli:~# dmraid -r /dev/sdc: sil, "sil_biaebhadcfcb", stripe, ok, 976771072 sectors, data@ 0 /dev/sdb: sil, "sil_biaebhadcfcb", stripe, ok, 976771072 sectors, data@ 0 root@tripoli:~# dmraid -ay RAID set "sil_biaebhadcfcb" already active fdisk Output root@tripoli:~# fdisk -l Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000b9b01 Device Boot Start End Blocks Id System /dev/sda1 * 1 32 248832 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 32 60802 488134657 5 Extended /dev/sda5 32 60802 488134656 8e Linux LVM Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x6ead5c9a Device Boot Start End Blocks Id System /dev/sdb1 1 60801 488384001 fd Linux raid autodetect Disk /dev/sdc: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xe6e2af28 Device Boot Start End Blocks Id System /dev/sdc1 1 60801 488384001 fd Linux raid autodetect

• Intel graphic chipset and NVIDIA Geforce GTX560

  - by antoine

  I have an NVIDIA Geforce GTX560 with two video projectors and I would like to use the onboard Intel Graphic Chipset to plug an additional monitor. I saw the question : How can I use both Intel onboard and Nvidia graphics at the same time? but the answer is so short that I was not convinced. My motherboard (GIGABYTE GA-H61M-D2P-B3 (rev. 1.0)) equipped with Intel H61 Chipset allow shared memory between onboard and PCIe cards. And Windows 7 allow me to use the three outputs thanks to Intel's driver. I'm able to use the onboard graphic card but without graphical interface for now. I think i need intel driver for that. But I would like to know if I can setup my displays in xorg.conf with something like : Section "Device" Identifier "Device0" Driver "intel" EndSection Section "Device" Identifier "Device1" Driver "nvidia" EndSection Section "Device" Identifier "Device2" Driver "nvidia" EndSection Does anyone have successfully setup something like that ? Or should I burn my head experimenting it by myself ? Or is there any good reasons to discouraged me to try ? Thanks for your help. Antoine PS : i'm using Ubuntu 10.10 for now, but I could switch to another version. PS2 : i also read this : Use 3 monitors w/built-in intel adapter + two old nvidia PCI cards on 10.10? which doesn't tell me more about the possibilities to use Intel Graphic and Nvidia at the same time EDIT : according to that : Can not get Dual Monitors to work on Different GPUs, I should be able to run two Xserver one on Intel the other on Nvidia. I will try and post the result here.

• Resolution changes when using switch

  - by Edward D

  So, the "real" resolution of my monitor is 1024x768. That's what I'd use on my docked Windows laptop, and what I'd use on my Xubuntu desktop connected directly. When I connect a switch, to switch between the two, however, the ubuntu machine's resolution changes. Everything's still proportional, and it still thinks it's doing 1024x768, but the icons and fonts appear larger. Not 800x600 larger, but still big. When I used Xubuntu Precise, I created an xorg.conf file to set a resolution of 1280x1024 which made it look the way it does without the switch ... as a workaround. When I upgraded to Trusty, I lost this. I tried to re-create it, but doesn't seem to load my file. Ideally, I'd like to correct the original problem, but I'd settle for being able to up the resolution. I searched for a while, and tried to do it, but I'm giving up ... please help me out.

• Ubuntu installed along side Win 8 but not shown in boot

  - by Mahesha999

  Actually the question says it all, but let me tell you what I did, so u may find exactly what might have went wrong: I have Win 8 installed on 500 GB HDD. SO I shrunk it four times for: partition 1 - the original partition containing Win 8 sys (118GB) partition 2 - NTFS formatted for my data (188GB) partition 3 - NTFS formatted for my data (100GB) partition 4 - NTFS formatted for Linux distro 1 (I reformatted it to ext4 during Ubuntu installation) (25GB) partition 5 - NTFS formatted for Linux distro 1 (21GB) So now I booted Ubuntu from USB (created from ubuntu-12.04-desktop-amd64.iso) and deleted last two partitions 4 and 5 to create: partition 1 - ext4 where I installed Ubuntu (25GB) partition 2 - Swap (4GB) partition 3 - unallocated space, not formatted yet (17GB) Ubuntu installation said it installed successfully and that I have to restart to boot in Ubuntu. But when I restart Windows 8 auto booted - there was no dual boot. After that I devided above 100GB partition to 80Gb and 20GB ones (since I read online that I should have /home in separate partition for convenience, so I created 20GB partition for it) So I went on to manually create boot entry using EasyBCD as below show in picture at below link http://s19.postimage.org/dof2zuvw3/Free_BCD.png When I created the entry, FreeBCD showed the information as follows: Windows Boot Manager -------------------- identifier {9dea862c-5cdd-4e70-acc1-f32b344d4795} device partition=\Device\HarddiskVolume2 description Windows Boot Manager locale en-US inherit {7ea2e1ac-2e61-4728-aaa3-896d9d0a9f0e} integrityservices Enable default {ea8167ad-d189-11e1-90e4-ab2f09569dcc} resumeobject {ea8167a3-d189-11e1-90e4-ab2f09569dcc} displayorder {ea8167ad-d189-11e1-90e4-ab2f09569dcc} {ea8167b1-d189-11e1-90e4-ab2f09569dcc} toolsdisplayorder {b2721d73-1db4-4c62-bf78-c548a880142d} timeout 10 displaybootmenu Yes Windows Boot Loader ------------------- identifier {ea8167ad-d189-11e1-90e4-ab2f09569dcc} device partition=C: path \Windows\system32\winload.exe description Windows 8 locale en-US osdevice partition=C: systemroot \Windows resumeobject {9bc7fdf7-3ae0-11e2-be77-806e6f6e6963} Real-mode Boot Sector --------------------- identifier {ea8167b1-d189-11e1-90e4-ab2f09569dcc} device partition=C: path \NST\AutoNeoGrub0.mbr description Ubuntu Notice the last bolded entry created.

Windows 8 was booting correctly but I was getting an error while booting Ubuntu taking me to GRUB Rescue. Please help am new to Linux world.

  My laptop has two hard drives, one 320GB HDD and a 30GB SSD. I installed Windows 8 on the HDD and Ubuntu on the SSD. However, after I installed Ubuntu, Windows 8 did not appear on the boot list.

• Wix XmlFile is keeping SqlDatabase from creating databases

  - by Grandpappy

  I've got a Wix project made up of several fragments. One of those fragments has the database components, another has a component that manipulates xml files. When I include the XmlFile element to manipulate a file, the databases defined by the SqlDatabase do not get created. If I comment out the XmlFile, then the databases do get created. Here are the two wix files with fragments that are being used: Database: <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:sql="http://schemas.microsoft.com/wix/SqlExtension"> <Fragment> <DirectoryRef Id="TARGETDIR"> <Component Id="Database1Creation" Guid="GUID_HERE"> <sql:SqlDatabase Id="Database1" Server="[DATABASE_SERVER]" Database="[DATABASE_NAME]" CreateOnInstall="yes" ConfirmOverwrite="no" DropOnUninstall="yes"> </sql:SqlDatabase> </Component> </DirectoryRef> </Fragment> </Wix> Xml Manipulation: <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:sql="http://schemas.microsoft.com/wix/SqlExtension" xmlns:util="http://schemas.microsoft.com/wix/UtilExtension"> <Fragment> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="ProgramFilesFolder"> <Directory Id="INSTALLDIR" Name="MyDirectory"> <Component Id="ServiceExecutables" Guid="GUID_HERE"> <File Id="File1" Name="File1.xml" Source="Source/File1.xml" /> <util:XmlFile Id="UpdateFile1" File="[INSTALLDIR]File1.xml" Action="setValue" ElementPath="//SomeContainer/SomeElement" Value="[SOME_VALUE]" /> </Component> </Directory> </Directory> </Directory> </Fragment> </Wix> There are other things that are also installed, but they don't appear to have any influence on the issue (I've removed everything else and tested the install). When looking at the install logs when using XmlFile and when not, they are almost exact copies of each other, except that the SqlDatabase calls would be completely missing, and the XmlFile calls would be in their place. Is there a known bug here? Or am I doing something I shouldn't be? This isn't a killer for our app, since I can move the things I'm putting in the xml file into the registry, but I'd rather not do that. I am using Wix 3.5.
