  • I'd like to preview a Word document on form.

    - by Tychumsempir
    I'm writing a VB program that fills in values within a word document. I'm utilizing the Microsoft Word 12.0 Object Library as a Reference. I'd like to provide a scrollable preview pane to my user that is within the form he or she is using. It would be even cooler if the user could edit the document through this pane. I've done Interop extensively, so I'm well aware of how to write and edit a Word document. I just want to put it into a frame and preview it. I'll probably try to select around the document based on what is changing as the user provides input so they can see what's being changed and where. Thoughts? Thanks

  • Using LINQ to isolate a particular obect from a list of objects

    - by dezkev
    Hello All, I am trying my hand at making an invaders clone. there are 30 aliens arranged in a 5x 6 matrix on screen. I need to give the bottom most alien the ability to fire a shot. I am using LINQ to group the aliens into 5 groups based on Location.X and then sort the groups descending.I then need to choose one of the groups ( that gives me 5 groups) and select the First alien in the group and use it;s coordinate to fire a shot. My code below ,well ,works , but aliens in ANY row are merrily firing shots- not just the bottom most. Pl look at my code below and tell me whats wrong. (r = an instance of the Random class, all aliens are in a list called invaders). { var query = (from inv in invaders group inv by inv.Location.X into invgroup orderby invgroup.Key descending select invgroup).ToList(); var invfirst = query[r.Next(query.Count)].First(); invaderShots.Add(new Shot( new Point(invfirst.Area.X + invfirst.Area.Width / 2, invfirst.Area.Y + invfirst.Area.Height + 5), displayrect, Shot.Direction.Down)); }

  • Include a version control tag in VSS

    - by Sjuul Janssen
    I was reading Code Complete 2 and it mentions this: Many version-control tools wil insert version information into a file. In CVS, for exmple the characters // $id$ Will Automaticly expand to // $id: ClassName.java, v 1.1 2004/02/05 00:36:42 ismene Exp $ So now I would like to do something similar with VSS for our SQL scripts I have been googling around for the answer but can't find it. Is this possible? can someone maybe point me in the right direction?

  • Select calls seems to not time out.

    - by martsbradley
    HI Folks, I have a threaded C++ program where up to three threads are calling select on a three separate socket descriptors waiting for data to become available. Each thread handles one socket and adds it to the readfds with a timeout of 300 seconds. After select returns if there is data available I'm calling recv to read it. Is there anything that I need to be aware of with winsock and threads because for some reason after a number of hours the select calls all seem to be not timing out. Can a multi threaded program select from a number of threads without issue? I know that I should have one thread listening to all three sockets however that would be a large change for this app and I'm only looking to apply a bug fix. cheers, Martin.

  • Problems encountered in changing a CRichEditCtrl selection color.

    - by dev ray
    I have written the following code after creating the CRichEditCtrl // 06112010 : The following code was added to highlight the textselection in black color instead of the default blue color of CRichEditCtrl. - 1311 { m_EditControl.SetSel(0,100); CHARFORMAT2 cf1; cf1.cbSize = sizeof(CHARFORMAT2); m_EditControl.GetSelectionCharFormat(cf1); cf1.dwMask = CFM_BACKCOLOR ; cf1.dwEffects &= ~CFE_AUTOBACKCOLOR; cf1.crBackColor = RGB(0,0,0); m_EditControl.SetSelectionCharFormat(cf1); m_EditControl.Invalidate(); } After this I am adding text, but the selection still comes in blue color instead of Black. Could someone please tell me what I am doing wrong?? Thanks, DeV

  • How work with common utils project.

    - by ais
    For example, I have some project Common.Utils.csproj and use it in all other projects. I can store its (Utils) sourses in one repository and modify it only there, register dll in gac and use it as dll in other projects, or I can clone sourse anywhere I need, include project in solution, use it as source and push modifications. So, what is best practice?

  • Can't get GetModuleFileNameA to work, keep getting error 'missing type specifier...'

    - by flavour404
    Hi, I am trying to use 'GetModuleFileNameA' but I keep getting the error 'c4430: missing type specifier - int assumed'. From reading the results from my google search I am guessing that it is from my use of NULL: char Filename[MAX_PATH]; //this is a char buffer GetModuleFileNameA(NULL, Filename, sizeof(Filename)); NULL is supposedly defined in #include stdio.h which I have included in my project, what am I doing wrong? Thanks.

  • assignment not working in a dll exported C++ class

    - by Jim Jones
    Using VS 2008 Have a C++ class in which I'm calling functions from a 3rd party dll. The definition in the header file is as follows: namespace OITImageExport { class ImageExport { private: SCCERR seResult; /* Error code returned. */ VTHDOC hDoc; /* Input doc handle returned by DAOpenDocument(). */ VTHEXPORT hExport; /* Handle to the export returned by EXOpenExport(). */ VTDWORD dwFIFlags; /* Used in setting the SCCOPT_FIFLAGS option. */ VTCHAR szError[256]; /* Error string buffer. */ VTDWORD dwOutputId; /* Output Format. */ VTDWORD dwSpecType; public: ImageExport(const char* outputId, const char* specType); void ProcessDocument(const char* inputPath, const char* outputPath); ~ImageExport(); }; } In the constructor I initialize two of the class fields having values which come from enumerations in the 3rd party dll: ImageExport::ImageExport(const char* outputId, const char* specType) { if(outputId == "jpeg") { dwOutputId = FI_JPEGFIF; } if(specType == "ansi") { dwSpecType = IOTYPE_ANSIPATH; } seResult = DAInit(); if (seResult != SCCERR_OK) { DAGetErrorString(seResult, szError, sizeof(szError)); fprintf(stderr, "DAInit() failed: %s (0x%04X)\n", szError, seResult); exit(seResult); } } When I use this class inside of a console app, with a main method in another file (all in the same namespace), instantiating the class object and calling the methods, it works like a champ. So, now that I know the basic code works, I open a dll project using the class header and code file. Course I have to add the dll macro, namely: #ifdef IMAGEDLL_EXPORTS #define DLL __declspec(dllexport) #else #define DLL __declspec(dllimport) #endif and changed the class definition to "class DLL ImageExport". Compiled nicely to a dll and .lib file (No errors, No warnings). Now to test this dll I open another console project using the same main method as before and linking to the (dll) lib file. Had problems, which when tracked down were the result of the two fields not being set; both had values of 0. Went back to the first console app and printed out the values: dwOutputId was 1535 (#define FI_JPEGFIF 1535) and dwSpecType was 2 (#define IOTYPE_ANSIPATH 2). Now if I was assigning these values outside of the class, I can see how the visibility could be different, but why is the assignment in the dll not working? Is it something about having a class in the dll?

  • Delay KeyUp Action if User is Typing (C#)

    - by Kirk
    I have a function that is being called when the user is typing in a search box. I want to wait for the user to finish typing before I actually execute the function. I know how to easily accomplish this in JavaScript with timeouts, but how would I go about doing the same thing in C#? Also, how long should I wait before I assume the user is done typing? 100ms?

  • TFS: Choose which workspace to add a solution too.

    - by Patricker
    I have a solution which I developed in VS2008 and which I am trying to add to Source Control (TFS 2010, though the issue happened in TFS 2008 as well). I have several TFS workspaces on my computer and I have access to several Team Projects. When I right click the solution in my Solution Explorer and choose the "Add Solution to Source Control" option I am never given an option of choosing which Workspace or which Team Project to add the existing solution too. VS2008 then proceeds to add it to the same team project every time. I have tried selecting an alternate workspace/team project in every window where I can see an option for it but it always adds it back to the same one. I even tried changing the name of my new workspace so that alphabetically it was the first thinking that it might be somehow related to that... no luck. I then tried goign to the Change Source Control window where you can add/remove bindings on a solution/project but that window also defaults to the same Team Project as trying to add the solution directly does... Any help would be greatly appreciated with this, maybe I'm just missing something?

  • Time is updating when a form is not even running

    - by onaclov2000
    A co-worker of mine had downloaded a vb example project a while back to see how to make a call or two, he discovered it today again, and noticed that while sitting in the IDE the time/date is updating automatically when the entire project is not even running. How does this work, we looked around for code but can't find anything giving it away. Any ideas?

  • Who plans to go back to using Web Applications in ASP.NET 4.0?

    - by Banzor
    So, it looks like Microsoft has gone back to pushing Web Application Projects* in ASP.NET 4.0. If you are like me, you converted to Website Projects in 2.0 and have never looked back. I recently spent some time trying to convert a Website Project to Web Application Project and was surprised at how tedious it was. So I am wondering what everyone is planning to do in VS 2010? Also, feel free to mention what you use now. Maybe I am the only sucker that converted to using Website Projects in 2.0... *Excluding MVC since it is the only option there

  • How do i use shortcuts/lnk on file servers?

    - by acidzombie24
    without using a database i wanted a file to point to the newest revision of a file. Someone suggested using a shortcut. Knowing i can rewrite file.ext to file.ext.lnk i thought it was a great idea. Then i tried it, my server (VS 2010rc) serves the shortcut rather then the file. Not what i wanted... How do i serve the file the shortcut is pointing to? NOTE: I am planing to use windows 2008 as my server so a solution should work on that as well. The OS i am running is windows 7.

  • directX texture appears incorrectly

    - by numerical25
    I finally managed to get a texture onto a cube sadly, but it is appearing incorrectly. as the below picture identifies. Anyways, I am not sure what it could be. My first guess is it could be my uv mapping or my vertex positioning is off. If someone could check and make sure thats good. The first element is the vertex position, second is the color, and third is the uv texture. //Create vectors and put in vertices // Create vertex buffer VertexPos vertices[] = { // BACK SIDES { D3DXVECTOR3(-5.0f, 5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(-5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(1.0,1.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(-5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(1.0,1.0)}, { D3DXVECTOR3(5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(1.0,1.0)}, // 2 FRONT SIDE { D3DXVECTOR3(-5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f) , D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(1.0,1.0)}, // 3 { D3DXVECTOR3(-5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(-5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(-5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,2.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, // 4 { D3DXVECTOR3(-5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, -5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, // 5 { D3DXVECTOR3(5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, 5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(0.0,2.0)}, // 6 {D3DXVECTOR3(-5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, {D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, {D3DXVECTOR3(-5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, {D3DXVECTOR3(-5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, {D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, {D3DXVECTOR3(-5.0f, -5.0f, 5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, }; My second guess could be an error that I am receiving as I run the program.

  • How to limit TCP writes to particular size and then block untlil the data is read

    - by ustulation
    {Qt 4.7.0 , VS 2010} I have a Server written in Qt and a 3rd party client executable. Qt based server uses QTcpServer and QTcpSocket facilities (non-blocking). Going through the articles on TCP I understand the following: the original implementation of TCP mentioned the negotiable window size to be a 16-bit value, thus maximum being 65535 bytes. But implementations often used the RFC window-scale-extension that allows the sliding window size to be scalable by bit-shifting to yield a maximum of 1 gigabyte. This is implementation defined. This could have resulted in majorly different window sizes on receiver and sender end as the server uses Qt facilities without hardcoding any window size limit. Client 1st asks for all information it can based on the previous messages from the server before handling the new (accumulating) incoming messages. So at some point Server receives a lot of messages each asking for data of several MB's. This the server processes and puts it into the sender buffer. Client however is unable to handle the messages at the same pace and it seems that client’s receiver buffer is far smaller (65535 bytes maybe) than sender’s transmit window size. The messages thus get accumulated at sender’s end until the sender’s buffer is full too after which the TCP writes on sender would block. This however does not happen as sender buffer is much larger. Hence this manifests as increase in memory consumption on the sender’s end. To prevent this from happening, I used Qt’s socket’s waitForBytesWritten() with timeout set to -1 for infinite waiting period. This as I see from the behaviour blocks the thread writing TCP data until the data has actually been sensed by the receiver’s window (which will happen when earlier messages have been processed by the client at application level). This has caused memory consumption at Server end to be almost negligible. is there a better alternative to this (in Qt) if i want to restrict the memory consumption at server end to say x MB's? Also please point out if any of my understandings is incorrect.

  • How to close a form in UserControl

    - by FJPoort
    I created a UserControl with the buttons Save, Close and Cancel. I want to close the form without saving on the Cancel button, prompt a message to save on the Close button and Save without closing on the Save button. Normally, I would have used this.Close() on the Cancel button, but the UserControl doesn't have such an option. So I guess I have to set a property for that. Scrolling down the "Questions that may already have your answer" section, I came across this question: How to close a ChildWindow from an UserControl button loaded inside it? I used the following C# code: private void btnCancel_Click(object sender, EventArgs e) { ProjectInfo infoScreen = (ProjectInfo)this.Parent; infoScreen.Close(); } This does the job for one screen, but I wonder if I have to apply this code for all the screen I have? I think there should be a more efficient way. So my question is: Do I need to apply this code for every form I have, or is there another (more efficient) way?
