http/html/ajax: show result before site is completely processed

- by chris

hi! I am looking for a way to show in a webapp in front of a task a wait-message and after it hide the message. The task is running a longer time. I dont know if it is possible at all. The problem is, so far I can see, that the site will be returned to the users browser AFTER the task is completed because the task is part of the site as a inline code replaces by the webserver interpreter (no matter if php, perl or whatever). The only solution I can imagine is to parallel the task with threads or processes and requery the state with ajax in the website. Any idea to do it less complex? Thanks for help! regards chris

Android - When to use Service

- by Chris

This question is related to my previous question: http://stackoverflow.com/questions/2786720/android-service-ping-url So I have an Android app that on the click of a button, opens up a web page. Now, in the background I want to call another http url for gathering stats. My question is does this have to be a service? I know a service is for background tasks that run for an indefinite period of time, while the user is busy doing something else. In my case, all I really need is to get the URL in the background, not show it to the user, instead show the web page to the user. Can I just not write code to get contents of the http url and fire up the activity that displays the web page? Coz all I want is to get the url in the background and be done with it. Or does this have to be done using the Service class? I am confused. Thanks Chris

Purchase music from iTunes store without leaving app?

- by chris.o.

Hi all, Is anyone aware of a standard way of allowing a user to purchase music from the app store without leaving the app? For instance, if a band has an album for sale on iTunes and then releases an iPhone game featuring the band members, is there a "standard way" to allow the user to buy songs without leaving the app? From what I can tell, there is not and, given that in the example above, the album is not content specifically for the app, it would not qualify for In-App purchase. Any suggestions? Thanks, Chris

Open GL ES 2.0 co-ordinate systems

- by Chris

Hi, I want to use Open GL ES 2.0 for a new game, but I have two questions. Q: The first is how do I set up perspective views in Open GL ES 2.0 - do I need to include Open GL ES 1.0 and use glOrtho, or is there a new way? Q: I want to use the 4th quadrant of a Cartesian co-ordinate system for my game and not use -0.5 to +0.5 for values on screen, how once the first question is answered can I achieve this? Other resources: http://iphonedevelopment.blogspot.com/2009/04/opengl-es-from-ground-up-part-3.html Thanks Chris

NoSql Crash Course/Tutorial

- by Chris Thompson

Hi all, I've seen NoSQL pop up quite a bit on SO and I have a solid understanding of why you would use it (from here, Wikipedia, etc). This could be due to the lack of concrete and uniform definition of what it is (more of a paradigm than concrete implementation), but I'm struggling to wrap my head around how I would go about designing a system that would use it or how I would implement it in my system. I'm really stuck in a relational-db mindset thinking of things in terms of tables and joins... At any rate, does anybody know of a crash course/tutorial on a system that would use it (kind of a "hello world" for a NoSQL-based system) or a tutorial that takes an existing "Hello World" app based on SQL and converts it to NoSQL (not necessarily in code, but just a high-level explanation). I see this having one solid answer, but if you guys feel like it should be community wiki, I'll be happy to change it. Thanks! Chris

JDT: How to retrieve the correct IJavaElement to a corresponding RefactoringDescriptor?

- by Chris

I implement the IRefactoringExecutionListener interface in an Eclipse plug-in to get notified when the user refactors his code, so I can update a visual editor displaying corresponding UML Boxes accordingly. Now I have a RefactoringDescriptor and cannot manage to map it's information (project name as String, new name as String and resource path as IPath) to my model. My model is basically a Hashmap in which fully qualified names (String) of types are mapped instances of IJavaElement, or more precisely: IType. How can I "convert" between the two representations so I can update my model? Regards, Chris

Resources check

- by Chris

hey I am frequently uploading my XCode iPhone projects to an svn repository to be build on another machine. My problem is that when I add resources to my project sometimes I forget to add the resource as relative to the project. I know one answer is to be more careful (not easy when your tired!) but if there was a way to run a script to check my resource paths are relative when I build and warn me if they are not it would be a great time saver for me. How would I go about doing this? Thanks Chris

Integration (math) in C++

- by Chris Thompson

Hi all, I'm looking for a library to find the integral of a given set of random data (rather than a function) in C++ (or C, but preferably C++). There is another question asking about integration in C but the answers discuss more how to integrate a function (I think...). I understand that this can be done simply by calculating the area under the line segment between each pair of points from start to finish, but I'd rather not reinvent the wheel if this has already been done. I apologize in advance if this is a duplicate; I searched pretty extensively to no avail. My math isn't as strong as I'd like it so it's entirely possible I'm using the wrong terminology. Thanks in advance for any help! Chris

.Net C#: support differnt Office versions

- by Chris

We created an application that uses Office 2007 (Excel 2007) to read in data from an Excel worksheet. However. I noticed that when I want to deploy the application on a system with Office 2003 installed, it crashes because other PIA's (and other dll's) need to be referenced for this version of office. Do I need to compile different versions of my application to be able to support different versions of Office or is there a more ellegant solution for this problem? I use Visual Studio 2010 (C#) and the .Net 4.0 platform. Many thanks Chris

C#/ASP.NET MVC 4 Instantiate Object Derived From Interface In Factory Method

- by Chris

Currently have a Factory class that features a GetSelector function, which returns a concrete implementation of ISelector. I have several different classes that implement ISelector and based on a setting I would like to receive the appropriate ISelector back. public interface ISelector { string GetValue(string Params); } public class XmlSelector : ISelector { public string GetValue(string Params) { // open XML file and get value } } public static class SelectorFactory { public static ISelector GetSelector() { return new XmlSelector(); // Needs changing to look at settings } } My question is what is the best way to store the setting? I am aware of using AppSettings etc. but I'm not sure whether I want to have to store strings in the web.config and perform a switch on it - just seems to be really tightly coupled in that if a new implementation of ISelector is made, then the Factory would need to be changed. Is there any way of perhaps storing an assembly name and instantiating based on that? Thanks, Chris

Android - Video Restart or Resume

- by Chris

Hi everyone, I am writing a simple android application with a class that extends activity, that plays a video from a url on the web. There is a button on top that on click takes the user to a web page. What I want to do is when the user is browsing the web page, if he hits the back button, I want him to come back to the main activity and restart the video. Is there a way to do this? Also, is there a way the video can be resumed from where it left off? Thank you. Chris

Java URLConnection Timeout

- by Chris

I am trying to parse an XML file from an HTTP URL. I want to configure a timeout of 15 seconds if the XML fetch takes longer than that, I want to report a timeout. For some reason, the setConnectTimeout and setReadTimeout do not work. Here's the code: URL url = new URL("http://www.myurl.com/sample.xml"); URLConnection urlConn = url.openConnection(); urlConn.setConnectTimeout(15000); urlConn.setReadTimeout(15000); urlConn.setAllowUserInteraction(false); urlConn.setDoOutput(true); InputStream inStream = urlConn.getInputStream(); InputSource input = new InputSource(inStream); And I am catching the SocketTimeoutException.

PHP, include with parameters

- by chris

hi! I have a PHP-file which will be called from a form. So it gets parameters over $_GET. Now I need the exact same functionality of this file, but not in such a form-call. I will include it in normal code with fixed parameters (which normally come from the form). So my file can work with the form AND without it. I know only the way with include and setting the $_GET in front of it. But I am not sure this is the most elegant way (I dont like the idea of setting things like $_GET). any other ways of doing this? br, chris

Jquery - Move Div around

- by Chris

Hi there guys, I am using Jquery Drag and drop to move divs across a page and this works perfectly. however what i would like is on each one of the div containers is to have a close button which when clicks removes the div from where it is and places it in a pre-defined div at the bottom like a widget gallery. How would this be accomplished? - below is my html.. thanks Chris <div class='column' id='leftcolumn'></div> <div class='column' id='rightcolumn'> <div class='dragbox'> <span class='close'>Close</span> Content In here </div> </div> <div class='column' id='widgetgallery></div>

Is there a graphics/game engine that supports PC & Mac?

- by Chris Masterton

Is their a graphics that runs on both Mac & PC? I've seen Unity and thats a possibility, I'm wondering if there are any other choices. Ideally I want to port the same C++ game code to both PC & Mac platforms, but let the underlying game/graphics engine take advantage of the appropriate hardware. edit: I'm looking on the level of Torque, Gamebryo & Unreal. A commercial solution is perfectly acceptable. Thanks, Chris

"exception at 0x53C227FF (msvcr110d.dll)" with SOIL library

- by Sean M.

I'm creating a game in C++ using OpenGL, and decided to go with the SOIL library for image loading, as I have used it in the past to great effect. The problem is, in my newest game, trying to load an image with SOIL throws the following runtime error: This error points to this part: // SOIL.c int query_NPOT_capability( void ) { /* check for the capability */ if( has_NPOT_capability == SOIL_CAPABILITY_UNKNOWN ) { /* we haven't yet checked for the capability, do so */ if( (NULL == strstr( (char const*)glGetString( GL_EXTENSIONS ), "GL_ARB_texture_non_power_of_two" ) ) ) //############ it points here ############// { /* not there, flag the failure */ has_NPOT_capability = SOIL_CAPABILITY_NONE; } else { /* it's there! */ has_NPOT_capability = SOIL_CAPABILITY_PRESENT; } } /* let the user know if we can do non-power-of-two textures or not */ return has_NPOT_capability; } Since it points to the line where SOIL tries to access the OpenGL extensions, I think that for some reason SOIL is trying to load the texture before an OpenGL context is created. The problem is, I've gone through the entire solution, and there is only one place where SOIL has to load a texture, and it happens long after the OpenGL context is created. This is the part where it loads the texture... //Init glfw if (!glfwInit()) { fprintf(stderr, "GLFW Initialization has failed!\n"); exit(EXIT_FAILURE); } printf("GLFW Initialized.\n"); //Process the command line arguments processCmdArgs(argc, argv); //Create the window glfwWindowHint(GLFW_SAMPLES, g_aaSamples); glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3); glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2); g_mainWindow = glfwCreateWindow(g_screenWidth, g_screenHeight, "Voxel Shipyard", g_fullScreen ? glfwGetPrimaryMonitor() : nullptr, nullptr); if (!g_mainWindow) { fprintf(stderr, "Could not create GLFW window!\n"); closeOGL(); exit(EXIT_FAILURE); } glfwMakeContextCurrent(g_mainWindow); printf("Window and OpenGL rendering context created.\n"); //Create the internal rendering components prepareScreen(); //Init glew glewExperimental = GL_TRUE; int err = glewInit(); if (err != GLEW_OK) { fprintf(stderr, "GLEW initialization failed!\n"); fprintf(stderr, "%s\n", glewGetErrorString(err)); closeOGL(); exit(EXIT_FAILURE); } printf("GLEW initialized.\n"); <-- Sucessfully creates an OpenGL context //Initialize the app g_app = new App(); g_app->PreInit(); g_app->Init(); g_app->PostInit(); <-- Loads the texture (after the context is created) ...and debug printing to the console CONFIRMS that the OpenGL context was created before the texture loading was attempted. So my question is if anyone is familiar with this specific error, or knows if there is a specific instance as to why SOIL would think OpenGL isn't initialized yet.

Problems Rendering Text in OpenGL Using FreeType

- by Sean M.

I've been following both the FreeType2 tutorial and the WikiBooks tuorial, trying to combine things from them both in order to load and render fonts using the FreeType library. I used the font loading code from the FreeType2 tutorial and tried to implement the rendering code from the wikibooks tutorial (tried being the keyword as I'm still trying to learn model OpenGL, I'm using 3.2). Everything loads correctly and I have the shader program to render the text with working, but I can't get the text to render. I'm 99% sure that it has something to do with how I cam passing data to the shader, or how I set up the screen. These are the code segments that handle OpenGL initialization, as well as Font initialization and rendering: //Init glfw if (!glfwInit()) { fprintf(stderr, "GLFW Initialization has failed!\n"); exit(EXIT_FAILURE); } printf("GLFW Initialized.\n"); //Process the command line arguments processCmdArgs(argc, argv); //Create the window glfwWindowHint(GLFW_SAMPLES, g_aaSamples); glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3); glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2); g_mainWindow = glfwCreateWindow(g_screenWidth, g_screenHeight, "Voxel Shipyard", g_fullScreen ? glfwGetPrimaryMonitor() : nullptr, nullptr); if (!g_mainWindow) { fprintf(stderr, "Could not create GLFW window!\n"); closeOGL(); exit(EXIT_FAILURE); } glfwMakeContextCurrent(g_mainWindow); printf("Window and OpenGL rendering context created.\n"); glClearColor(0.2f, 0.2f, 0.2f, 1.0f); //Are these necessary for Modern OpenGL (3.0+)? glViewport(0, 0, g_screenWidth, g_screenHeight); glOrtho(0, g_screenWidth, g_screenHeight, 0, -1, 1); //Init glew int err = glewInit(); if (err != GLEW_OK) { fprintf(stderr, "GLEW initialization failed!\n"); fprintf(stderr, "%s\n", glewGetErrorString(err)); closeOGL(); exit(EXIT_FAILURE); } printf("GLEW initialized.\n"); Here is the font file (it's slightly too big to post): CFont.h/CFont.cpp Here is the solution zipped up: [solution] (https://dl.dropboxusercontent.com/u/36062916/VoxelShipyard.zip), if anyone feels they need the entire solution. If anyone could take a look at the code, it would be greatly appreciated. Also if someone has a tutorial that is a little more user friendly, that would also be appreciated. Thanks.

Map and fill texture using PBO (OpenGL 3.3)

- by NtscCobalt

I'm learning OpenGL 3.3 trying to do the following (as it is done in D3D)... Create Texture of Width, Height, Pixel Format Map texture memory Loop write pixels Unmap texture memory Set Texture Render Right now though it renders as if the entire texture is black. I can't find a reliable source for information on how to do this though. Almost every tutorial I've found just uses glTexSubImage2D and passes a pointer to memory. Here is basically what my code does... (In this case it is generating an 1-byte Alpha Only texture but it is rendering it as the red channel for debugging) GLuint pixelBufferID; glGenBuffers(1, &pixelBufferID); glBindBuffer(GL_PIXEL_UNPACK_BUFFER, pixelBufferID); glBufferData(GL_PIXEL_UNPACK_BUFFER, 512 * 512 * 1, nullptr, GL_STREAM_DRAW); glBindBuffer(GL_PIXEL_UNPACK_BUFFER, 0); GLuint textureID; glGenTextures(1, &textureID); glBindTexture(GL_TEXTURE_2D, textureID); glTexImage2D(GL_TEXTURE_2D, 0, GL_R8, 512, 512, 0, GL_RED, GL_UNSIGNED_BYTE, nullptr); glBindTexture(GL_TEXTURE_2D, 0); glBindTexture(GL_TEXTURE_2D, textureID); glBindBuffer(GL_PIXEL_UNPACK_BUFFER, pixelBufferID); void *Memory = glMapBuffer(GL_PIXEL_UNPACK_BUFFER, GL_WRITE_ONLY); // Memory copied here, I know this is valid because it is the same loop as in my working D3D version glUnmapBuffer(GL_PIXEL_UNPACK_BUFFER); glBindBuffer(GL_PIXEL_UNPACK_BUFFER, 0); And then here is the render loop. // This chunk left in for completeness glUseProgram(glProgramId); glBindVertexArray(glVertexArrayId); glBindBuffer(GL_ARRAY_BUFFER, glVertexBufferId); glEnableVertexAttribArray(0); glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 20, 0); glVertexAttribPointer(0, 2, GL_FLOAT, GL_FALSE, 20, 12); GLuint transformLocationID = glGetUniformLocation(3, 'transform'); glUniformMatrix4fv(transformLocationID , 1, true, somematrix) // Not sure if this is all I need to do glBindTexture(GL_TEXTURE_2D, pTex->glTextureId); GLuint textureLocationID = glGetUniformLocation(glProgramId, "texture"); glUniform1i(textureLocationID, 0); glDrawArrays(GL_TRIANGLES, Offset*3, Triangles*3); Vertex Shader #version 330 core in vec3 Position; in vec2 TexCoords; out vec2 TexOut; uniform mat4 transform; void main() { TexOut = TexCoords; gl_Position = vec4(Position, 1.0) * transform; } Pixel Shader #version 330 core uniform sampler2D texture; in vec2 TexCoords; out vec4 fragColor; void main() { // Output color fragColor.r = texture2D(texture, TexCoords).r; fragColor.g = 0.0f; fragColor.b = 0.0f; fragColor.a = 1.0; }

Multi Pass Blend

- by Kirk Patrick

I am seeking the simplest working example of a two pass HLSL pixel shader. It can do anything really, but the main idea is to perform "ping ponging" to take the output of the first pass and then send it for the second pass. In my example I want to draw to the R channel and then draw to the G channel and produce a simple Venn Diagram in the shader, but need to detect overlap. I can currently detect one or the other but not overlap. There are a red and green circle overlapping, and I want to put a dynamic texture map in the overlap region. I can currently put it in either or. Below is how it looks in the shader. -------------------------------- Texture2D shaderTexture; SamplerState SampleType; ////////////// // TYPEDEFS // ////////////// struct PixelInputType { float4 position : SV_POSITION; float2 tex0 : TEXCOORD0; float2 tex1 : TEXCOORD1; float4 color : COLOR; }; //////////////////////////////////////////////////////////////////////////////// // Pixel Shader //////////////////////////////////////////////////////////////////////////////// float4 main(PixelInputType input) : SV_TARGET { float4 textureColor0; float4 textureColor1; // Sample the pixel color from the texture using the sampler at this texture coordinate location. textureColor0 = shaderTexture.Sample(SampleType, input.tex0); textureColor1 = shaderTexture.Sample(SampleType, input.tex1); if (input.color[0]==1.0f && input.color[1]==1.0f) // Requires multi-pass textureColor0 = textureColor1; return textureColor0; } Here is the calling code (that needs to be modified) m_d3dContext->IASetVertexBuffers(0, 2, vbs, strides, offsets); m_d3dContext->IASetIndexBuffer(m_indexBuffer.Get(), DXGI_FORMAT_R32_UINT,0); m_d3dContext->IASetPrimitiveTopology(D3D11_PRIMITIVE_TOPOLOGY_TRIANGLELIST); m_d3dContext->IASetInputLayout(m_inputLayout.Get()); m_d3dContext->VSSetShader(m_vertexShader.Get(), nullptr, 0); m_d3dContext->VSSetConstantBuffers(0, 1, m_constantBuffer.GetAddressOf()); m_d3dContext->PSSetShader(m_pixelShader.Get(), nullptr, 0); m_d3dContext->PSSetShaderResources(0, 1, m_SRV.GetAddressOf()); m_d3dContext->PSSetSamplers(0, 1, m_QuadsTexSamplerState.GetAddressOf());

How do I render from one render target to another?

- by Chaotikmind

I have two render targets: a fake backbuffer; a special render target where I do all my rendering. a light render target; where I render my light fx. I'm sure I'm rendering correctly on both. The problem arises when I overlay the light render target onto the fake backbuffer by drawing a quad covering it: DxEngine.DrawSprite(0.0f, 0.0f, 0.0f, (float)DxEngine.GetWidth(), (float)DxEngine.GetHeight(), 0xFFFFFFFF, LightSurface->GetTexture()); Regardless of what's in the light target, nothing is rendered onto the other target. I tried clearing the light target with full-white or full-black, but still get nothing. Fake backbuffer created with Direct3dDev->CreateTexture(Width, Height, 1, D3DUSAGE_RENDERTARGET, D3DFMT_X8R8G8B8, D3DPOOL_DEFAULT, &Texture, nullptr); Light render target created with Direct3dDev->CreateTexture(Width, Height, 1, D3DUSAGE_RENDERTARGET, D3DFMT_A8R8G8B8, D3DPOOL_DEFAULT, &Texture, nullptr); I also tried to create both with D3DFMT_A8R8G8B8, again without difference. Both targets have the same width and height. Only the fixed pipeline is used DirectX setup for rendering : Direct3dDev->SetSamplerState(0, D3DSAMP_MINFILTER, D3DTEXF_LINEAR ); Direct3dDev->SetSamplerState(0, D3DSAMP_MAGFILTER, D3DTEXF_LINEAR ); Direct3dDev->SetSamplerState(0, D3DSAMP_MIPFILTER, D3DTEXF_NONE ); Direct3dDev->SetSamplerState(0, D3DSAMP_ADDRESSU, D3DTADDRESS_WRAP ); Direct3dDev->SetSamplerState(0, D3DSAMP_ADDRESSV, D3DTADDRESS_WRAP ); Direct3dDev->SetRenderState(D3DRS_CULLMODE, D3DCULL_NONE); Direct3dDev->SetRenderState(D3DRS_LIGHTING, false); Direct3dDev->SetRenderState(D3DRS_ZENABLE, D3DZB_TRUE); Direct3dDev->SetRenderState(D3DRS_ZWRITEENABLE,D3DZB_TRUE); Direct3dDev->SetRenderState(D3DRS_ZFUNC,D3DCMP_LESSEQUAL); Direct3dDev->SetRenderState(D3DRS_ALPHABLENDENABLE, true ); Direct3dDev->SetRenderState(D3DRS_ALPHAREF, 0x00000000ul); Direct3dDev->SetRenderState(D3DRS_ALPHATESTENABLE, true); Direct3dDev->SetRenderState(D3DRS_ALPHAFUNC,D3DCMP_GREATER); Direct3dDev->SetRenderState(D3DRS_SRCBLEND, D3DBLEND_SRCALPHA ); Direct3dDev->SetRenderState(D3DRS_DESTBLEND, D3DBLEND_INVSRCALPHA ); Direct3dDev->SetTextureStageState(0, D3DTSS_COLORARG1, D3DTA_TEXTURE); Direct3dDev->SetTextureStageState(0, D3DTSS_COLORARG2, D3DTA_DIFFUSE); Direct3dDev->SetTextureStageState(0, D3DTSS_COLOROP, D3DTOP_MODULATE); Direct3dDev->SetTextureStageState(0, D3DTSS_ALPHAARG1, D3DTA_TEXTURE); Direct3dDev->SetTextureStageState(0, D3DTSS_ALPHAARG2, D3DTA_DIFFUSE); Direct3dDev->SetTextureStageState(0, D3DTSS_ALPHAOP, D3DTOP_MODULATE); Direct3dDev->SetTextureStageState(0, D3DTSS_RESULTARG, D3DTA_CURRENT); Direct3dDev->SetTextureStageState(0, D3DTSS_TEXCOORDINDEX, D3DTSS_TCI_PASSTHRU); //ensure the first stage is not used for now Direct3dDev->SetTextureStageState(1, D3DTSS_COLOROP, D3DTOP_DISABLE); How can I do this right?

Outlook 2007 Does Not Accept Login Credentials, OWA Webmail Does. Troubleshooting Advice?

- by Chris

I am trying to connect Outlook 2007 to Exchange (Hosted Exchange from Rackspace). Soon, I will need to roll this out for our entire office. With the Exchange account added to Outlook, Outlook starts up and asks for the user's username and password. Unfortunately, it doesn't like the password I use for it. I can confirm this username (email address) and password combo works by using Outlook WebMail, and another user (in another network/office) confirmed the Exchange account does work within his Outlook client. In my network/office, I can confirm that an Outlook 2007 client (under Windows 7) can connect to the Hosted Exchange server from Rackspace. However, I have not been able to get Outlook 2007 (under Windows XP SP3) to connect to the very same Exchange server Outlook 2007 (under Windows 7) can connect to. Outlook continuously prompts me for the username and password and does not accept the correct combination. Now, regarding the Outlook client that cannot connect/login to Exchange: The user has full admin rights on the workstation We do not run a domain controller/LDAP The firewall on the workstation has been disabled Real time file scanning in Microsoft Security Essentials has been disabled There are no virus scanning applications that would interface with Outlook or an email server. The Exchange account is setup to run on a newly created Outlook profile The network firewall does not log any blocked attempts A packet capture at the router reveals communication between the workstation and the Exchange server or proxy (though, this is SSL encrypted, so I don't know what the computers are saying) I have applied a fix (Added DWORD value of 0 for DefConnectOpts under HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\RPC) that was recommended to make RPC function when the workstation does not have a default gateway set. Workstation is configured as DHCP. This fix did nothing, and it may be worth noting the RPC subkey was not present until I added it. RPC service is running on the workstation The program is not running under any compatibility mode. Side note: Outlook 2007 installs with compatibility mode for XP enabled by default in windows 7. Outlook 2007 will not even try to connect to exchange if this compatibility mode is checked. In windows xp, I tried checking compatibility mode for windows 2000, and was unable to connect to exchange as well. Here is the specific configuration I've used in a blank outlook profile: Microsoft Exchange Server: ##MASKED##-MBX-C18.mex07a.mlsrvr.com Username: (Full Email Address: [email protected]) Password: ##MASKED## Outlook Anywhere: Connect to Microsoft Exchange using HTTP Exchange Proxy Settings: Proxy Server: mex07a.emailsrvr.com Check "Connect using SSL only" Under "Only connect to proxy servers...", enter: msstd:mex07a.emailsrvr.com Check "On fast networks, connect using HTTP first, then connect using TCP/IP" Check "On slow networks, connect using HTTP first, then connect using TCP/IP" Proxy authentication settings: Basic Authentication Notes: mex07a.mlsrvr.com and mex07a.emailsrvr.com may look incorrect at first glance, but this is not a typo - these instructions were handed down from rackspace and are confirmed to be working, just not on this workstation. I have tried to use the RpcPing utility but must have been using it wrong. I got as far as "Bad Interface Descriptor". It would seem to me getting Outlook and Exchange to work together would be a breeze, especially since everything is done over port 80 with web services. Unfortunately, the user is stuck with WebMail access only, because Outlook won't accept the Exchange credentials. Do you have any ideas of other things I could try to debug this issue further? Any and all help is greatly appreciated. Thank you! -Chris
