• Is there a way to change the maximum width of a window without using the WM_GETMINMAXINFO message?

  - by David

  I want to change the imposed Windows maximum width that a window can be resized to, for an external application's window (not my C#/WinForms program's window). The documentation of GetSystemMetrics for SM_CXMAXTRACK says: "The default maximum width of a window that has a caption and sizing borders, in pixels. This metric refers to the entire desktop. The user cannot drag the window frame to a size larger than these dimensions. A window can override this value by processing the WM_GETMINMAXINFO message." Is there a way to modify this SM_CXMAXTRACK value (either system wide or for one particular window), without processing the WM_GETMINMAXINFO message? Maybe an undocumented function, a registry setting, etc.? (Or: The documentation for MINMAXINFO.ptMaxTrackSize says: "This value is based on the size of the virtual screen and can be obtained programmatically from the system metrics SM_CXMAXTRACK and SM_CYMAXTRACK." Maybe there is a way to change the size of the virtual screen?) Thank you

• Python to see if a file falls into a date range

  - by tod

  I have a script that I want to have an if statement check if a file falls between several specified date periods as it searches directories. I have been able to get the time in %Y-%m-%d format for the file, but I can't seem to be able to specify a date range for python to go through. Any ideas/help? Here's what I have so far for name in files: f = os.path.join(root, name) dt = os.path.getmtime(f) nwdt = time.gmtime(dt) ndt = time.strftime('%Y-%m-%d', nwdt)

• Store profile image of all users into single directory or per subdirectory id?

  - by Luccas

  I'm using amazon s3 as storage for users profile pic. I see that many websites generates large random filenames and put them into the same root directory like: http://xxx.us-east-1.amazonaws.com/aHR0cHM6Ly9mYmNkbi1wcm9maWxlLWEuYWthbWFpaGQubmV0L2hwcm9maWxlLWFrLWFzaDIvMjczMzkxXzEwMDAwMDMxMjAxMzg5OV81NTk3MjM4Mzdfbi5qcGc.jpg And my question is: What are the pros and cons of that approach? If I palce them into different directories, what problems I will have in future? http://xxx.us-east-1.amazonaws.com/users/id/username.jpg or http://xxx.us-east-1.amazonaws.com/users/id/random_number.jpg Thanks!

• Descending list ordered by file modification time

  - by user62367

  How can i generate a list of files in a directory [e.g.: "/mnt/hdd/PUB/"] ordered by the files modification time? [in descending order, the oldest modified file is at the lists end] ls -A -lRt would be great: https://pastebin.com/raw.php?i=AzuSVmrJ but if a file is changed in a directory it lists the full directory...so the pastebined link isn't good [i don't want a list ordered by "directories", i need a "per file" ordered list] os: openwrt..[no perl - not enough space for it :( + no "stat", or "file" command] Thank you!

• What causes my borderless C++ app to crash when overriding WndProc?

  - by Ste

  I use a form with border NONE. I need to override WndProc for resize and move form. However, using this code, my app crashes! static const int WM_NCHITTEST = 0x0084; static const int HTCLIENT = 1; static const int HTCAPTION = 2; protected: virtual void Form1::WndProc(System::Windows::Forms::Message %m) override { switch (m.Msg) { case WM_NCHITTEST: if (m.Result == IntPtr(HTCLIENT)) { m.Result = IntPtr(HTCAPTION); } break; } Form1::WndProc(m); } virtual System::Windows::Forms::CreateParams^ get() override { System::Windows::Forms::CreateParams^ cp = __super::CreateParams; cp->Style |= 0x40000; return cp; } How can I fix my code not to crash but still allow my form to be moved and resized?

• Removing files on a limit access backup server

  - by Bart van Heukelom

  I have an account on a backup server but it's full, so I need to clear it. The problem is that It's only accessible via FTP, SFTP and Rsync (no shell) Deleting lots of small files (as in, multiple full Linux installations), which I have to do, is undoable over FTP/SFTP because it cannot recursively delete directories in one command (Yes, most clients will fake this by issueing all the seperate commands for you but the overhead is huge and the process takes several days...well it crashes before that). What do I do?

  I've found all my Outlook data files which contain all my emails at the following paths: C:\Users\C\AppData\Local\Microsoft\Outlook C:\Users\C\AppData\Roaming\Microsoft\Outlook and C:\Users\C\My Documents\Outlook Files\ I've migrated all these and copied it to my new machine at the same directories however my configuration is not there! None of my email pop/smtp settings are there, only the pst is loaded with my emails but all other configuration is gone, where precisely is that configuration stored?

• Returning a C++ reference in a const member functionasses

  - by Chris Kaminski

  A have a class hierarchy that looks somethign like this: class AbstractDataType { public: virtual int getInfo() = 0; }; class DataType: public AbstractDataType { public: virtual int getInfo() { }; } class Accessor { DataType data; public: const AbstractDataType& getData() const { return(data); } } Well, GCC 4.4 reports: In member function ‘const AbstractDataType& Accessor::getData() const’: error: invalid initialization of reference of type ‘const AbstractDataType&’ from expression of type ‘const DataType’ Where am I going wrong - is this a case where I MUST use a pointer?

• C++ Class Inheritance architecture - preventing casting

  - by Some One

  I have a structure of base class and a couple of inherited classed. Base class should be pure virtual class, it should prevent instantiation. Inherited classes can be instantiated. Code example below: class BaseClass { public: BaseClass(void); virtual ~BaseClass(void) = 0; }; class InheritedClass : public BaseClass { public: InheritedClass1(void); ~InheritedClass1(void); }; class DifferentInheritedClass : public BaseClass { public: DifferentInheritedClass(void); ~DifferentInheritedClass(void); }; I want to prevent the following operations to happen: InheritedClass *inherited1 = new InheritedClass(); DifferentInheritedClass *inherited2 = new DifferentInheritedClass (); BaseClass *base_1 = inherited1; BaseClass *base_2 = inherited2; *base_1 = *base_2;

• GNU-Screen still has only old groups for my username.

  - by Dan

  I was recently added to a group on the unix server. My active screen session has not been update to the new groups: $groups A B C D $screen -r $groups A B C Without closing my screen session is there a way for me to use my new privileges in the screen session? Or if not, is there at least a way I can save all of the different directories each of the tabs are on? Thanks, Dan

• Which Files located under C:\ are Necessary for Win7 to Boot?

  - by k0pernikus

  I had my greatest moment of incredible stupidity and deleted all hidden files of the Windows partition, most commonly known as C:\, while running Gnu/Linux. All the directories are intact. I instantly unmounted it, and run ntfsundelete, though of the thousands entries I wonder which ones I have to recover. So hence my question: Which files located directly under C:\ are necessary for Windows 7 to boot?

• Oracle Professional Developer, Ver. 6.0.33 for MS-DOS

  - by Frank Developer

  Hi, I'm trying to install this fossil in DOS 6.22, which is running in Microsoft Virtual PC 2007. I'm hoping that some of you veteran Oracle developers have any recollection of in what order do these diskette images need to be loaded, since I don't have any documentation available for 6.0.33. A friend emailed me the following 720K diskette images: INSTALLE.IMG RDBMS1.IMG RDBMS2.IMG RDBMS3.IMG RSF.IMG SQLLDR1.IMG SQLLDR2.IMG UTIL1.IMG UTIL2.IMG UTIL3.IMG Within Virtual PC, I capture a diskette image, one at a time, into Drive A: VPC's floppy disk emulation supports FAT12, so the supported diskette formats can be: 720K or 1.44MB. If anyone happens to have documentation for this legacy version, I would greatly appreciate a copy of it! Thank You.

• Hierarchy inheritance

  - by reito

  I had faced the problem. In my C++ hierarchy tree I have two branches for entities of difference nature, but same behavior - same interface. I created such hierarchy trees (first in image below). And now I want to work with Item or Base classes independetly of their nature (first or second). Then I create one abstract branch for this use. My mind build (second in image below). But it not working. Working scheme seems (third in image below). It's bad logic, I think... Do anybody have some ideas about such hierarchy inheritance? How make it more logical? More simple for understanding? Image Sorry for my english - russian internet didn't help:) Update: You ask me to be more explicit, and I will be. In my project (plugins for Adobe Framemaker) I need to work with dialogs and GUI controls. In some places I working with WinAPI controls, and some other places with FDK (internal Framemaker) controls, but I want to work throw same interface. I can't use one base class and inherite others from it, because all needed controls - is a hierarchy tree (not one class). So I have one hierarchy tree for WinAPI controls, one for FDK and one abstract tree to use anyone control. For example, there is an Edit control (WinEdit and FdkEdit realization), a Button control (WinButton and FdkButton realization) and base entity - Control (WinControl and FdkControl realization). For now I can link my classes in realization trees (Win and Fdk) with inheritence between each of them (WinControl is base class for WinButton and WinEdit; FdkControl is base class for FdkButton and FdkEdit). And I can link to abstract classes (Control is base class for WinControl and FdkControl; Edit is base class for WinEdit and FdkEdit; Button is base class for WinButton and FdkButton). But I can't link my abstract tree - compiler swears. In fact I have two hierarchy trees, that I want to inherite from another one. Update: I have done this quest! :) I used the virtual inheritence and get such scheme (http://img12.imageshack.us/img12/7782/99614779.png). Abstract tree has only absolute abstract methods. All inheritence in abstract tree are virtual. Link from realization tree to abstract are virtual. On image shown only one realization tree for simplicity. Thanks for help!

• Question regarding common class

  - by Rocky Singh

  I have following two classes: public class A : System.Web.UI.WebControls.Button { public virtual string X { get { object obj = ViewState["X"]; if (obj != null) return (string)obj; return null; } set { ViewState["X"] = value; } } protected override void OnLoad(EventArgs e) { X=2; } } and public class B : System.Web.UI.WebControls.TextBox { public virtual string X { get { object obj = ViewState["X"]; if (obj != null) return (string)obj; return null; } set { ViewState["X"] = value; } } protected override void OnLoad(EventArgs e) { X=2; } } As you must be seeing the class A and B have exactly the same code , my question is how can I make a common class for it and use these two classes.

• Renaming dates under windows cmd

  - by ldigas

  I have a bunch of directories (folders, if you like) that follow this pattern \20121022 Description of the directory's contents goes here\ (some don't have it, just the date) and I need to rename them to follow the following pattern \2012-10-22 Description of the directory's contents ...\ Is there a way to do it using Windows cmd and the tools that come with it (namely, ren)? If not, what would be the most portable way to do it? I have a very restricted set of privileges on the machine I'm doing this on.

• Are view models used in rails?

  - by Valentin Vasilyev

  I'm starting to develop a small application in ruby on rails and many questions arise. I should say that I have about 1 year of experience with ASP.NET MVC and feel at home with models views and controllers. I've been using view models extensively (with the help of AutoMapper) and now wondering if view models are used similarly in rails camp. From various examples (rails casts mainly) I've gathered that it is common to either combine data from multiple models right in your view (which is frowned upon in ASP.NET MVC), or to use virtual attributes on models to obtain "missing" data. I know that business model should not be modelled after UI needs, for example there should not be a 'password confirm' property in your model, this should be a view model property. Rails virtual properties seem to violate this principle. How is it done in rails? Thanks.

• C++: warning: '...' declared with greater visibility than the type of its field '...::<anonymous>'

  I'm getting these two warnings (with GCC 4.2 on MacOSX): /Users/az/Programmierung/openlierox/build/Xcode/../../src/main.cpp:154:0 /Users/az/Programmierung/openlierox/build/Xcode/../../src/main.cpp:154: warning: 'startMainLockDetector()::MainLockDetector' declared with greater visibility than the type of its field 'startMainLockDetector()::MainLockDetector::<anonymous' /Users/az/Programmierung/openlierox/build/Xcode/../../src/main.cpp:154:0 /Users/az/Programmierung/openlierox/build/Xcode/../../src/main.cpp:154: warning: 'startMainLockDetector()::MainLockDetector' declared with greater visibility than its base 'Action' In this code: struct Action { virtual ~Action() {} virtual int handle() = 0; }; static void startMainLockDetector() { /* ... */ struct MainLockDetector : Action { bool wait(Uint32 time) { /* ... */ } int handle() { /* ... */ } }; /* ... */ } I'm not exactly sure what these warnings mean (what visibility?) and how to fix them. (I really want the class MainLockDetector to be local for that function only.) I have already compiled the same code with a lot of other compilers (clang, GCC 3.*, GCC 4.0, GCC 4.4, etc) and never got any warning for this code.
