    - by IcanMakeIt
    I am using complicated SQL queries, i have to use SqlQuery ... in simple way: MODEL: public class C { public int ID { get; set; } [NotMapped] public float Value { get; set; } } CONTROLLER: IEnumerable<C> results = db.C.SqlQuery(@"SELECT ID, ATAN(-45.01) as Value from C); return View(results.ToList()); VIEW: @model IEnumerable<C> @foreach (var item in Model) { @Html.DisplayFor(modelItem => item.Value) } and the result for item.Value is NULL.

  • Read text and print each (byte) character in separate line

    - by user2967663
    preforming this code to read file and print each character \ (byte) in separate line works well with ASCII void preprocess_file (FILE *fp) { int cc; for (;;) { cc = getc (fp); if (cc == EOF) break; printf ("%c\n", cc); } } int main(int argc, char *argv []) { preprocess_file (stdin); exit (0); } but when i use it with UTF-8 encoded text it shows unredable character such as ï » ? ? § ? „ ? … ? ¤ ? ´ ? and advice ?

  • Does Windows 7 support multiple simultaneous nVidia graphics cards with different drivers?

    - by mckenzieg1
    On one of my dev machines at work (currently running XP), I have two nVidia graphics cards: Quadro NVS 440 (my original card, for my three primary monitors) GeForce GTX 275 (just added, for CUDA development) I can get both cards to work OK by installing the latest GeForce drivers, but I get some annoying-but-not-crippling display artifacts on the Quadro's screens (mostly scattered black rectanges where repainting fails for a few bits of UI in certain applications). Under XP, this seems to be the best I can do. I can use Device Manager to supposedly install different nVidia drivers for the two cards (the latest Quadro drivers for the NVS, the latest GeForce drivers for the GTX), but I actually end up with the same driver for both, because the driver dlls all have the same names and get installed on top of one another in the system directory. I have read that Win7 has a new video driver architecture that better supports multiple heterogeneous cards. Does anyone know if that will handle my scenario? If so, it will give me a compelling reason to get that machine on Win7 ASAP.

  • ATI Radeon Drivers works with which linux distribution and version?

    - by amit.codename13
    I have ATI Mobility Radeon HD 5850 graphics card. Almost every new linux distribution seems to have an issue with it, when i install the drivers. Working without utilizing the graphics card leaves me so unproductive. So i made a plan to use older versions of linux, any distribution suitable as a desktop distribution. UPDATE: The kind of problems that i am facing are, 1) After installing drivers the system boots and hangs, 2) There are unusual lines over the screen 3) After upgrade system doesn't start properly(hangs the usual old way) The kind of answers i am looking for is, distribution X(the newer the version the better) doesn't have the above problem after installing drivers for ATI Mobility Radeon HD 5850 graphics card. UPDATE: The new drivers released by AMD seems to fix all the issues, although they are still beta Thanks

  • Can 32-bit print drivers work on 64-bit windows?

    - by Matt
    I'm reading around and it seems that 32 bit drivers do not work under 64 bit windows. Is this true? since 32-bit applications can run under 64 bit windows it seems ridiculous that 32-bit printer drivers cannot. Are printer drivers run at the kernel level? Sounds like we're in for driver hell for our RDP environments.

  • How can I fix broken i915 drivers for Intel GPUs?

    - by Alen Mujezinovic
    I've got troubles getting the i915 drivers to work correctly on my laptop (HP Pavilion DM4 2101ea). Specifically, the laptop screen goes black and stays black after the splash graphic when booting both from USB key and from harddrive. To get anything on to the display after the splash screen I have to boot either with acpi=off nomodeset i915.modeset=0 I'd rather not turn ACPI off because I like my fans spinning and nomodeset is a bit overkill, so for now I'm booting with i915.modeset=0. Unfortunately, this turns off KMS and my current maximum resolution on the laptop screen is fixed to 1024x768 instead of its real capability. When not setting any of the above boot flags and I plug in an external monitor, the external monitor works fine. When booting with the flags, the external monitor works fine too, but can only do 1024x768 and can't do anything else than mirroring the laptop display. I did upgrade the i915 drivers from 2.17 that ship with Precise to 2.19 which are the most recent ones but without luck of getting anything to display. Here's my lspci output: 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.2 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 3 (rev b5) 00:1c.4 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 5 (rev b5) 00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation HM65 Express Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 01:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) 02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

Here's a complete Xorg.log file from a boot into a black screen: https://gist.github.com/479ce06454e47d6123e1 The graphics card is a Intel HD 3000 integrated GPU. I've never had problems with Intel hardware on Ubuntu before so this is very surprising. If you could provide a method to make i915 work, suggest alternative drivers a way to boot with i915.modeset=0 but higher resolutions and KMS on or explain what is happening and how to fix it I'll give you an answer badge. :) Thanks

  • Can't install ATI proprietary drivers in 12.10. Unity is Missing

    - by EApubs
    I have a laptop with ATI Radeon 6770M HD Hybrid graphics card. In Ubuntu 12.04, I installed the fglrx driver through "additional drivers" and it worked. (I can even switch GPUs). But in the new Ubuntu 12.10, after installing, Unity won't load. Only the mouse and the wallpaper. If I initialize the settings sudo aticonfig --initial then after rebooting it gives a warning saying I'm in low graphics mode! How to fix this? PS : Earlier i used software source to install the drivers. But when using the terminal, I got this warning : update-alternatives: warning: forcing reinstallation of alternative /usr/lib/fglrx/ld.so.conf because link group x86_64-linux-gnu_gl_conf is broken Update : Filed a bug report in launchpad : https://bugs.launchpad.net/fglrx/+bug/1068661

  • How do I install drivers for a Konica Minolta 200?

    - by th3pr0ph3t
    This copy machine / scanner / network printer works with Windows but no drivers are available for linux. When Ubuntu supports a printer it works fine but this one is not supported. I found the drivers in: http://onyxftp.mykonicaminolta.com/download/SearchResults.aspx?productname=bizhub%20200 //But I don't know how to install them, nor which one to download. //How can I install this driver? EDIT: The file with the driver is here http://onyxftp.mykonicaminolta.com/DownloadFile/Download.ashx?fileid=18571&productid=865 Inside the archive there is a .deb package that installs correctly but doesn't work. So far the question is: "How can I make it work?"

  • How do I install drivers for graphics and sound?

    - by Sid
    I recently shifted to Ubuntu 12.04 from windows 7. I completely removed Windows and then installed Ubuntu. However, I can't find a way to download and install drivers for my video and audio hardware like I used to be able to do in Windows. Could someone please explain to me how software and drivers, in general, are installed on Ubuntu. Is installing through 'Ubuntu Software Center' the only way to install them? My laptop model is: Dell Inspiron 14 N4010 (i5/4gb/500gb). Kindly help. Thanks in advance.

  • "Unable To Load Client Print Control" - SSRS Printing problems again

    - by mamorgan1
    Please forgive me as my head is spinning. I have tried so many solutions to this issue, that I'm almost not sure where I am at this point. At this point in time I have these issues in my Production, Test, and Dev environments. For simplicity sake, I will just try to get it working in Dev first. Here is my setup: Database/Reporting Server (Same server): Windows Server 2003 SP2 SQL Server 2005 SP3 Development Box: Windows 7 Visual Studio 2008 SP1 SQL Server 2008 SP1 (not being used in this case, but wanted to include it in case it is relative) Internet Explorer 8 Details: * I have a custom ASP.NET application that is using ReportViewer to access reports on my Database/Reporting Server. * I am able to connect directly to Report Manager and print with no trouble. * When I view source on the page with ReportViewer, it says I'm am using version 9.0.30729.4402 . * The classid of the rsclientprint.dll that keeps getting installed to my c:\windows\downloaded program files directory is {41861299-EAB2-4DCC-986C-802AE12AC499}. * I have tried taking the rsclientprint.cab file from my Database/Reporting Server and installing it directly to my Development Box and had no success. I made sure to unregister the previously installed dll first. I feel like I have read as many solutions as I can, and so I turn to you for some assistance. Please let me know if I can provide further details that would be helpful. Thanks

  • Finding out max available print area

    - by Armagan
    I'm trying to find out max available area on my printer. I've printed a simple rectangle trying out different boundary variables. My question is, why doesn't first two work correctly? They don't print a full rectangle on the paper, only the left and top sides are drawn. Why does only the third one prints a full rectangle? I was under the impression of that all three should be working correctly. What am I missing? Here's my code: this.printDocument1.DefaultPageSettings.Margins = new Margins(0, 0, 0, 0); ... private void PrintPage(object sender, PrintPageEventArgs e) { //Method 1, no right and bottom sides are printed e.Graphics.DrawRectangle(new Pen(Color.Black, 1), e.PageBounds); //Method 2, same as Method 1 e.Graphics.DrawRectangle(new Pen(Color.Black, 1), e.MarginBounds); //Method 3, works correctly e.Graphics.DrawRectangle(new Pen(Color.Black, 1), new Rectangle((int)e.Graphics.VisibleClipBounds.X, (int)e.Graphics.VisibleClipBounds.Y, (int)e.Graphics.VisibleClipBounds.Width, (int)e.Graphics.VisibleClipBounds.Height)); }

  • Cant print contents of a custom file

    - by ZaZu
    Hello, Im trying to scan contents from a random file into an array in a structure. Then I want to print those contents on screen. (NOTE: The following code is from a bigger program, this is just a sample, but all structures and arrays used are needed as declared ) The contents of the file being tested are simply: 5 4 3 2 5 3 4 2 #include<stdio.h> #define first 500 #define sec 500 struct trial{ int f; int r; float what[first][sec]; }; int trialtest(trial *test); int trialdisplay(trial *test); main(){ trial test; trialtest(&test); trialdisplay(&test); } int trialtest(trial *test){ int z,x,i; FILE *inputf; inputf=fopen("randomfile.txt","r"); for(i=0;i<5;i++){ fscanf(inputf,"%f",&(*test).what[z][x]); } fclose(inputf); return 0; } int trialdisplay(trial *test){ int i,z,x; printf("printing\n\n\n"); for (i=0;i<10;i++){ printf("%f",(*test).what[z][x]); } return 0; } The problem is, I get this error whenever I run the code .. I cant really understand whats going on : Any suggestions ? Thanks alot !

  • scanf a byte then print it out?

    - by Sarah
    I've searched around to see if I can find this answer but I can't seem to (please let me know if I'm wrong). I am trying to use scanf to read in a byte, an unsigned int and a char in one .c file and I am trying to access this byte in a different .c file and print it out. (I have already checked to make sure I have included all the appropriate parameters everywhere) But I keep getting errors. The warnings are: database.c: In function ‘addCitizen’: database.c:23:2: warning: format ‘%hhu’ expects argument of type ‘int’, but argument 2 has type ‘byte *’ [-Wformat] database.c:24:2: warning: format ‘%u’ expects argument of type ‘unsigned int’, but argument 2 has type ‘int *’ [-Wformat] database.c:25:2: warning: format ‘%c’ expects argument of type ‘int’, but argument 2 has type ‘char *’ [-Wformat] where I'm scanf'ing: // Request loop while (count-- != 0) { while (1){ // Get values from the user int error = scanf ("%79s %hhu %u %c", tname, &tdist, &tyear, &tgender); addCitizen(db, tname, &tdist, &tyear, &tgender); where I'm printing: void addCitizen(Database *db, char *tname, byte *tdist, int *tyear, char *tgender){ //needs to find the right place in memory to put this stuff and then put it there printf("\nName is: %79s\n", tname); printf("District is: %hhu\n", tdist); printf("Year of birth is: %u\n", tyear); printf("Gender is:%c\n", tgender); I'm not sure where I'm going wrong?

  • Printf in assembler doesn't print

    - by Gaim
    Hi there, I have got a homework to hack program using buffer overflow ( with disassambling, program was written in C++, I haven't got the source code ). I have already managed it but I have a problem. I have to print some message on the screen, so I found out address of printf function, pushed address of "HACKED" and address of "%s" on the stack ( in this order ) and called that function. Called code passed well but nothing had been printed. I have tried to simulate the environment like in other place in the program but there has to be something wrong. Do you have any idea what I am doing wrong that I have no output, please? Thanks a lot EDIT: This program is running on Windows XP SP3 32b, written in C++, Intel asm there is the "hack" code CPU Disasm Address Hex dump Command Comments 0012F9A3 90 NOP ;hack begins 0012F9A4 90 NOP 0012F9A5 90 NOP 0012F9A6 89E5 MOV EBP,ESP 0012F9A8 83EC 7F SUB ESP,7F ;creating a place for working data 0012F9AB 83EC 7F SUB ESP,7F 0012F9AE 31C0 XOR EAX,EAX 0012F9B0 50 PUSH EAX 0012F9B1 50 PUSH EAX 0012F9B2 50 PUSH EAX 0012F9B3 89E8 MOV EAX,EBP 0012F9B5 83E8 09 SUB EAX,9 0012F9B8 BA 1406EDFF MOV EDX,FFED0614 ;address to jump, it is negative because there mustn't be 00 bytes 0012F9BD F7DA NOT EDX 0012F9BF FFE2 JMP EDX ;I have to jump because there are some values overwritten by the program 0012F9C1 90 NOP 0012F9C2 0090 00000000 ADD BYTE PTR DS:[EAX],DL 0012F9C8 90 NOP 0012F9C9 90 NOP 0012F9CA 90 NOP 0012F9CB 90 NOP 0012F9CC 6C INS BYTE PTR ES:[EDI],DX ; I/O command 0012F9CD 65:6E OUTS DX,BYTE PTR GS:[ESI] ; I/O command 0012F9CF 67:74 68 JE SHORT 0012FA3A ; Superfluous address size prefix 0012F9D2 2069 73 AND BYTE PTR DS:[ECX+73],CH 0012F9D5 203439 AND BYTE PTR DS:[EDI+ECX],DH 0012F9D8 34 2C XOR AL,2C 0012F9DA 2066 69 AND BYTE PTR DS:[ESI+69],AH 0012F9DD 72 73 JB SHORT 0012FA52 0012F9DF 74 20 JE SHORT 0012FA01 0012F9E1 3120 XOR DWORD PTR DS:[EAX],ESP 0012F9E3 6C INS BYTE PTR ES:[EDI],DX ; I/O command 0012F9E4 696E 65 7300909 IMUL EBP,DWORD PTR DS:[ESI+65],-6F6FFF8D 0012F9EB 90 NOP 0012F9EC 90 NOP 0012F9ED 90 NOP 0012F9EE 31DB XOR EBX,EBX ; hack continues 0012F9F0 8818 MOV BYTE PTR DS:[EAX],BL ; writing 00 behind word "HACKED" 0012F9F2 83E8 06 SUB EAX,6 0012F9F5 50 PUSH EAX ; address of "HACKED" 0012F9F6 B8 3B8CBEFF MOV EAX,FFBE8C3B 0012F9FB F7D0 NOT EAX 0012F9FD 50 PUSH EAX ; address of "%s" 0012F9FE B8 FFE4BFFF MOV EAX,FFBFE4FF 0012FA03 F7D0 NOT EAX 0012FA05 FFD0 CALL EAX ;address of printf This code is really ugly because I am new in assembler and there mustn't be null bytes because of buffer-overflow bug

  • Quick question regarding this issue, Why doesnt it print out the second value(converted second value

    - by sil3nt
    Quick question, What have I done wrong here. The purpose of this code is to get the input into a string, the input being "12 34", with a space in between the "12" and "32" and to convert and print the two separate numbers from an integer variable known as number. Why doesn't the second call to the function copyTemp, not produce the value 34?. I have an index_counter variable which keeps track of the string index and its meant to skip the 'space' character?? what have i done wrong? thanks. #include <stdio.h> #include <string.h> int index_counter = 0; int number; void copyTemp(char *expr,char *temp); int main(){ char exprstn[80]; //as global? char tempstr[80]; gets(exprstn); copyTemp(exprstn,tempstr); printf("Expression: %s\n",exprstn); printf("Temporary: %s\n",tempstr); printf("number is: %d\n",number); copyTemp(exprstn,tempstr); //second call produces same output shouldnt it now produce 34 in the variable number? printf("Expression: %s\n",exprstn); printf("Temporary: %s\n",tempstr); printf("number is: %d\n",number); return 0; } void copyTemp(char *expr,char *temp){ int i; for(i = index_counter; expr[i] != '\0'; i++){ if (expr[i] == '0'){ temp[i] = expr[i]; } if (expr[i] == '1'){ temp[i] = expr[i]; } if (expr[i] == '2'){ temp[i] = expr[i]; } if (expr[i] == '3'){ temp[i] = expr[i]; } if (expr[i] == '4'){ temp[i] = expr[i]; } if (expr[i] == '5'){ temp[i] = expr[i]; } if (expr[i] == '6'){ temp[i] = expr[i]; } if (expr[i] == '7'){ temp[i] = expr[i]; } if (expr[i] == '8'){ temp[i] = expr[i]; } if (expr[i] == '9'){ temp[i] = expr[i]; } if (expr[i] == ' '){ temp[i] = '\0'; sscanf(temp,"%d",&number); index_counter = i+1; //skips? } } // is this included here? temp[i] = '\0'; }

  • Looking for streaming xml pretty printer in C/C++ using expat or libxml2

    - by Mark Zeren
    I'm looking for a streaming xml pretty printer for C/C++ that's either self contained or that uses libxml2 or expat. I've searched a bit and not found one. It seems like something that would be generally useful. Am I missing an obvious tool that does this? Background: I have a library that outputs xml without whitespace all on one line. In some cases I'd like to pretty print that output. I'm looking for a BSD-ish licensed C/C++ library or sample code that will take a raw xml byte stream and pretty print it. Here's some pseudo code showing one way that I might use this functionality: void my_write(const char* buf, int len); PrettyPrinter pp(bind(&my_write)); while (...) { // ... get some more xml ... const char* buf = xmlSource.get_buf(); int len = xmlSource.get_buf_len(); int written = pp.write(buf, len); // calls my_write with pretty printed xml // ... error handling, maybe call write again, etc. ... } I'd like to avoid instantiating a DOM representation. I already have dependencies on the expat and libxml2 shared libraries, and I'd rather not add any more shared library dependencies.
