  • Count rows against to SQL server (2005) table?

    - by David.Chu.ca
    I have a simple question with two options to get count of rows in a SQL server (2005). I am using VS 2005. There are two options to get the count: SELECT id FROM Table1 WHERE dt >= startDt AND dt < endDt;; I get a list of ids from above call in cache and then I get count by List.Count. Another option is SELECT COUNT(*) FROM Table1 WHERE dt >= startDt AND dt < endDt; The above call will get the count directly. The issue is that I had several cases of exceptions with the second method: timeout. What I found is that the table1 is too big with millions of data. When I used the first option, it seems OK. I am confused by the fact that Count() takes more time than getting all the rows(is that true?). Not sure if the aggregation call with Count() would cause SQL server to create temporary table or cache on server side and it would result in slow performance when table is too big? I am not sure what is the best way to get the count?

  • How to get Resharper to show a Refactoring that it already has.

    - by AngryHacker
    Whenever Resharper encounters code like this: (treeListNode.Tag as GridLine).AdvertiserSeparation = 5; it presents you with a possible fix (since treeListNode.Tag as GridLine might be null). It says: 'Replace with Direct Cast', which turns the code into the following: ((GridLine) treeListNode.Tag).AdvertiserSeparation = 5; This is great. However, when it encounters code like this: GridLine line = treeListNode.Tag as GridLine; line.AdvertiserSeparation = 5; Resharper simply displays a warning 'Possible System.NullReferenceException', but does not offer me to 'Replace with Direct Cast'. Is there a way to make Resharper offer me this refactoring, since it already has it?

  • What's the best way to change the namespace of a highly referenced class?

    - by vanslly
    I am attempting to move a highly referenced class from one namespace to another. Simply moving the file into the new project which has a different root namespace results in over 1100 errors throughout my solution. Some references to the class involve fully qualified namescape referencing and others involve the importing of the namespace. I have tried using a refactoring tool (Refactor Pro) to rename the namespace, in the hope all references to the class would change, but this resulted in the aforementioned problem. Anyone have ideas of how to tackle this challenge without needing to drill into every file manually and changing the fully qualified namespace or importing the new one if it doesn't exist already? Thanks.

  • How do I return JSON data from a partial view FormMethod.Get?

    - by MrM
    I have the following code that posts to my Search Json. The problem is the url redirects to the json search and displays the raw json data. I would like to return to a table in my partialView instead. Any thoughts on how I can achieve this? <div> @using (Html.BeginForm("Search", "Home", Formmethod.Get, new {id="search-form"})){ ... <button id="search-btn">Search</button> } </div> <div> <table id="search-results">...</table> </div> My home controller works fine but to make sure the picture is clear... public JsonResult Search(/*variables*/) { ... return Json(response, JsonRequestBehavior.AllowGet); } And I get redirected to "Search/(all my variables)

  • value of Identity column returning null when retrieved by value in dataGridView

    - by Raven Dreamer
    Greetings. I'm working on a windows forms application that interacts with a previously created SQL database. Specifically, I'm working on implementing an "UPDATE" query. for (int i = 0; i < dataGridView1.RowCount; i++) { string firstName = (string)dataGridView1.Rows[i].Cells[0].Value; string lastName = (string)dataGridView1.Rows[i].Cells[1].Value; string phoneNo = (string)dataGridView1.Rows[i].Cells[2].Value; short idVal = (short)dataGridView1.Rows[i].Cells[3].Value; this.contactInfoTableAdapter.UpdateQuery(firstName, lastName, phoneNo, idVal); } The dataGridView has 4 columns, First Name, Last Name, Phone Number, and ID (which was created as an identity column when I initially formed the table in SQL). When I try to run this code, the three strings are returned properly, but dataGridView1.Rows[i].Cells[3].Value is returning "null". I'm guessing this is because it was created as an identity column rather than a normal column. What's a better way to retrieve the relevant ID value for my UpdateQuery?

  • MFC CDialog not showing

    - by Jesus_21
    here is my problem : In my Solution, I have 2 projects, one is a lib in which I created a ressource file (mylib.rc) and a dialog template in it. Then I made a class which inherits CDialog and uses this template. But when I instantiate it and call DoModal(), nothing appends... here the code of my class, is something wrong with it ? MyDialog.h /*MyDialog.h*/ #pragma once #include "../../../resource.h" class MyDialog : public CDialog { enum {IDD=IDD_DLGTEMPLATE}; public: MyDialog(CWnd* pParent = NULL); virtual ~MyDialog(); protected: virtual BOOL OnInitDialog(); DECLARE_MESSAGE_MAP() private: afx_msg void OnBnClickedOk(); afx_msg void OnBnClickedCancel(); }; MyDialog.cpp /*MyDialog.cpp*/ #include "stdafx.h" #include "MyDialog.h" MyDialog::MyDialog(CWnd* pParent /*=NULL*/) : CDialog(IDD_DLGTEMPLATE, pParent) {} MyDialog::~MyDialog() {} BOOL MyDialog::OnInitDialog() { return TRUE; } BEGIN_MESSAGE_MAP(MyDialog, CDialog) ON_BN_CLICKED(IDOK, &MyDialog::OnBnClickedOk) ON_BN_CLICKED(IDCANCEL, &MyDialog::OnBnClickedCancel) END_MESSAGE_MAP() void MyDialog::OnBnClickedOk() { OnOK(); } void MyDialog::OnBnClickedCancel() { OnCancel(); }

  • What are useful functions for drawing text (MFC)?

    - by kobac
    I'm creating a line chart control, and I need to write (or better say draw) the axis names and axis values. I found DrawText and TextOut functions, but the text they show is flickering and don't know how to set the font and text orientation (I will need vertical text orientation as well as horizontal). Are there any other functions you could recoommend or how to use these stated above and get the results I need? Thanks in advance. Cheers.

  • Dynamic expansion of a Crystal report...

    - by Chathuranga Chandrasekara
    I have a crystal report consisting of several pages. Each page consists of a several fields that are populated from database. Suppose the following example : Name : aaaaaa Education Background:bbbbbbb Age:cc In my case the Education Background's details (bbbbbbb here) may consist of several words or several pages. If I set a large space for it, it will waste a big space on report (Yes. May be a paper) in a case of short answer. How can I eliminate this problem? Does crystal reports provide a way to dynamically expand the space?

When I register my DLL with regsvr32.exe, it shows registration successful, but when I check the entries in regedit, there is no entry in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID. There is only one entry in Computer\HKEY_LOCAL_MACHINE\TypeLib with the guid mentioned in the project. Can anyone help me on this?

  • C#: standard Windows menu bars in Windows Forms

    - by BoltClock
    I noticed that adding a MenuStrip (from the VS Toolbox) to my form design doesn't yield a menu bar like many native Windows applications. Instead I get a menu bar like VS's own. None of the style settings for MenuStrip appear to mimic the much more common native menu bar. Is there a way to add a menu bar to my Windows Forms application that looks the same as the one you see in Notepad, Task Manager, Windows Explorer and others? (Preferably with the designer, but I wouldn't mind adding it programmatically either.)

  • Changing the namespace for a Web Reference in a Project to be Made Into a VS Project Template

    - by kdmurray
    When I add a web reference to a project, it comes up with a default namespace of: com.wpdevs.myservice. This is the namespace I'd have expected it to use in the application. When I add the using statement to the project, I have to add: using MyProject.com.wpdevs.myservice; I'd like to find a way to eliminate having to reference the project name in the using statement. The project I'm putting together now is destined to be converted into a VS Project template and having that rather strange reference in there, or even having a per-project reference, isn't something I'd like to have in the project.

  • .net c# text box date with mask - setup

    - by flavour404
    I have a c# .net project and want an input text box for a date value. I want it to display a default value of mm/dd/yyyy and then allow users to enter valid dates. I have tried using a masked text box but it doesn't like having the above format. If i try and use //__ looks naff and so does 00/00/0000 and of course if you put in '0' like 03/11/2009 you get 3/11/29 because the 0's are deleted as part of the mask - so what is the best way to set up an input box like this, effectively with a mask, only allowing numbers, and validation (though at this point I am not so worried about that). This seems so simple and isn't. Thanks, R.

  • What is the difference between clearcase and vss in label a release?

    - by raj
    Hi, We are using clearcase as our SCM. I have not much experience with clearcase. Now we are about to release our code to production. I want to label my code as I have done using VSS in my previous projects. But in clearcase labeling is not as easy as in VSS. clearcase is asking to create a label type before label a folder in VOB. I don't understand the concept of creating label type? Any guidance on this will be highly appreciated.

  • Exporting dataset to Excel file with multiple sheets in ASP.NET

    - by engg
    In C# ASP.NET 3.5 web application, I need to export multiple datatables (or a dataset) to an Excel 2007 file with multiple sheets, and then provide the user with 'Open/Save' dialog box, WITHOUT saving the Excel file on the web server. I have used Excel Interop before. I have been reading that it's not efficient and is not the best approach to achieve this and there are more ways to do it, 2 of them being: 1) Converting data in datatables to an XML string that Excel understands 2) Using OPEN XML SDK 2.0. It looks like OPEN XML SDK 2.0 is better, please let me know. Are there any other ways to do it? I don't want to use any third-party tools. If I use OPEN XML SDK, it creates an excel file, right? I don't want to save it on the (Windows 2003) server hard drive (I don't want to use Server.MapPath, these Excel files are dynamically created, and they are not required on the server, once client gets them). I directly want to prompt the user to open/save it. I know how to do it when the 'XML string' approach is used. Please help. Thank you.

  • Icons in Windows Form Applications (VS2008)

    - by typoknig
    This is yet another question about .ico files. I have read through many pages trying to figure this out but I am unable to. When I go to Properties - Application of my Windows Form Application there is a place for me to pick the icon for my application. I have made a 32x32 icon and it takes it just fine, but the image is grainy when it is applied to my .exe file, like it is a picture that has been expanded more than it should have. 1.) Why is this? 2.) Is there any .ico file size other than 32x32 than a Windows Form Application can accept? I have tried 48x48 but it doesn't like that. I just want my .exe file to look nice!

  • How do I programatically add an article page to a sharepoint site?

    - by soniiic
    I've been given the task of content migration from another CMS system to SharePoint 2010. The data in the old system is fairly easy to capture and the page hierarchy is simple so I'm not worried about that. However, I am completely flummoxed about how to even create a page in code. I'm using the Microsoft.SharePoint.Client namespace as I do not have sharepoint installed on my system and am wanting to code this up as a console application and so I'm using I'm using ClientContext. (On the other hand, I am willing to go into other solutions if necessary). My end-game: To get a page uploaded into some folder hierarchy which uses a master page, has the page title in a header web part, and a big ol' content-editable web part in the body so any user can come along and edit the content. Things I've tried so far: Using FileCollection.Add() to add an aspx file to the folder "Site Pages". This renders the html in the browser but doesn't enable any features for the user to edit the page Using ListItemCollection.Add() to add a page to the site, but I didn't know what fields I needed. Also I remember it came up with a runtime error saying I should use FileCollection.Add() Uploading to 'Site Pages' instead of 'Pages' So many others... ow my head :( The only plausible thing I can see on the net is to use the PublishingPage type along with PublishingWeb. However, PublishingWeb can only be constructed from an SPWeb object which requires me to be actually hosting the sharepoint application on my workstation. If anyone can lend a hand that would be greatly appreciated :)
