I was looking to build a Data Access Layer for my new web based application, I'm using ASP.NET. I'm want to build a framework not only for this application but also want to utilize it for my future projects.
Actually my main aim is to make a framework, from DAC, DAL, BL to GUI. I want suggestions from you guys that what should i adopt, what give me flexibility, which suits for both small and large size applications.
I am doing a project on the CRM application which sending and receiving sms using the vb.net language. I am no where to conclusions of my project because I could not build the application. I have found many examples but the problem some of the examples some uses the sms gateway or the AT commands. I could not differentiate which one to use? I have a dateline to finish this project of mine.Most of the example does not look like a CRM application.
In the very near future I'll have to develop an application that uses multiple screens.
So I'll give you a practical example:
I have 4 screens where different pricing infomation is being displayed. At any given time, I have to show a Promotion which is a single image that needs to be displayed across all of the screens with text scrolling across the screens.
Now I'm wondering what the best way would be to achieve this.
At first I was thinking of using one form and to stretch it across 4 screens, while I create 4 'areas' on the form that represent a screen. However when you extend a form this big I'm afraid the text is going to look horrible.
Then I was thinking of using 4 forms and split up the image into 4 different images which are displayed on the different screens. However to get a scrolling text right on 4 different forms, that's going to take some trial and error.
how I can achieve this form of digital signage?
I want to use VB.Net unless this would seem impossible and I have to use other software?
I am building an application with VB 2005 with sql server. I am using a listbox to populate items from the database. The listbox Sorted property has been set to True and also the query uses order by clause on the Name field. The items in the listbox look like
Bean Began Cat Category Detail Delta
MY problem is when the user tries to select an item, say Detail, having focus on the listbox, when pressing the keys D the item Detail selects but on next key e, it goes on to the Item starting with E. (in vb6 listbox property Sorted = true would solve this problem, which i am not getting with vb 2005/2008)
So, how can i achieve the multiple keypress on the listbox (without using any textbox to select items) to select the typed items in the list.
I am in the process of developing a messaging framework for a windows application that sends messages to a java application. To be precise when the win app wants to send a message it simply drops the message in a common database table which will be picked up by the java app. The windows application is deployed across 10 application servers (10 instances) over citrix for load balancing.Each instance of the application is capable of sending a message to the java application and each of these messages should have a unique id. From my end I need to make sure every message generated has to carry a unique id so that they can be identified when necessary. All the messages can be cleared every day or two.i am not quite sure about a best method of achieving this. Initially I wanted to create a static method that serves the next available id (incrementing the last id by 1). But this approach willn't guarantee unique number as the application starts only when at least one user is logged on. For e.g .On one server the app starts when a user logs in, he then sends a message and then the application stops when that user logs off. So when a next request for the app comes to that server a new instance will be started.
im building a application that plays internet radios, and im stuck at one place, so i want it to be possible for the user to be able to add their own radio stations, i have a form for that, has; text boxes for the; name and for the URL, and a button to save it to the listbox called "User Radio's", now here is the problem, should i use a database where i store the preset radio's + where the user will save their radios or how exactly do i save this? i also need help with playing the radio station that the user saved in the listbox, and how will i play the preset radio's that are saved in database, populate the listbox from the database?
Building a large application using 3 tier architecture in vb.net. Question: I am a vb.net developer. I have developed small and medium size application with 2 tier architecture. Now I am going to develop a large application. I have decided to develop that application using 3 tier architecture. So I studied about 3 tier. Now I know how what is 3 tier and how to develop a simple application. And also I studied about .Net Remoting and Web services. In my project, 7 modules are available. Each module has 3 layers. How can I manage in a Single Solution?
I want to build an application that checks every second for certain windows and then react according to that.
My Goal:I'm building the application for a pc in a Students Home with about 10 users. To create 10 different user accounts for windows will be annoying and crowded, because new people come in every year(or couple of months) and then old accounts have to be deleted and new ones created.
I want to build an application that accepts folderPaths or window names.Lets say user1 creates a folder with the name "Susan" that she wants to protect (her personal files/picture/work will be stored there. She opens the application, selects the folder. The application saves the folder path and her password that she enters.
If the application detects that a user is trying to open/move/delete/copy/whatever that folder, the app must pop up a password box. Correct password gives her the freedom she wants, wrong password just ignores the open/move/delete/copy/whatever command.
My new office project is based on an MVP design and is in VB.NET (.NET 3.5), using multiple libraries (like EntLib, internal corporate framework, etc.). The number of DLLs used as references is so huge (almost 50) that when I try to build/debug the application in VS2008, it takes almost 3-4 minutes to get the website running successfully.
Wanted to know if there are any settings/areas which upon some modifications can help me reduce the build time? and what exactly can be the major reasons behind this long loading duration?
I use VB 2005 Express @ home for developing stuff. I am wondering if anyone knows how to run a script automatically after building my application. When I click build I want it to compile my InnoSetup installer and also zip up my executable + readme.txt file into AppName-version.zip. Right now I manually do it, and it's not that big of a deal, but if I am just wondering if it's possible. I think I can do it with full VS, so I will check it at work, but I am wondering if I can write a plugin or something if VB2k5X doesn't have an option do it already built in.
how to work with distributed application in vb.net that automatically stored data into server? How to configure to ensure the consistency of data being stored.
Currently working on a web-service with Oracle10g as back-end. Here is my problem.
1. The table I need to populate has 100 columns. I have no control over the design of the table.
2. I wanted to use the "deriveparameters" method of OracleCommandBuilder, but found out that this is "costly" in terms of performance. What I initially planned to do was to derive the parameters from an open connection, close the connection, then maybe cache the parameters obtained but I don't know if this is possible.
I am unsure how big of a hit the performance will get if I continue using the "deriveparameters" method WITHOUT caching the parameters driven. The environment is as follows
-intranet -around 2000 users -users spread out in different parts of the country
I am not familiar where they will put the web pages of the application, the web service and the database. I don't know if they'll be putting it in different servers or on one server, but that's something we cannot control too, that's why I am looking for the best approach.
I just don't want to hard-code all that parameters and if, for instance, we need to change some properties/parameters, it will be a pain to maintain the code. It would be nice if someone here can point a way to automate the whole thing w/o the performance of the system taking a hit.
I designed an application to download a file from the Internet onto a selected location on the local computer. This application too, has a form-building error.Debug Error Message: An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object.
I imported some code I found a few months ago for a client server messaging program from vs2003 and everything appeared to be ok, apart from a couple of niggles such as the windows form designer generated code being visible on the main form code page but i could live with that. I just tried to add a splash screen but when I went to the application tab to set it up there is no enable application framework checkbox and no windows application framework groupbox. I tried running my application again and now the xp visual style has gone and it looks terrible, is there anyway to get the application framework back on again or do I have to start a new project and copy and past all my code into the new project.
I'm currently using MS Visual Studio 2008 Express Edition. My .NET Framework version is 3.5. I made an application in VS 2008 and it worked perfectly. However, when I ran it at my friend's place (who's got .NET Framework 1.1), it didn't run. Now, I know that the framework incompatibility is the issue.So, what I ask is, how do I code the application so as to make it run on Framework 1.1 as well while still using VS 2008?
I have a Windows 7 machine and I see that Microsoft does not recommend Visual Studio 2003 on the computer (Windows 7). How can I develop an application for the .net framework 1.0 then?
This sounds weird and dumb but supposedly is this possible to run .Net application without installing .net framework? Is there anyway of embedding reference .dlls into the respective application? This came in my mind because I made a small notepad application in vb.net < 1mb in size and to run it, it requires full .net framework.
I need to use linq in C# Windows form application working with .Net Framework 2 not 3.5 . I Know it may be some sort of stupidity to do that. but i need that for some special reasons. Can i import just linq libraries to my project by anyway ? or there is no way except for using 3.5 ?
I am developing an application using VB.Net which is a simple executable which is to be run from a network drive of our company servers. Most users can access this executable without issue - others however can open the executable but have no connection to our database (even though when running the executable off a local drive such as C:, the database works no problem).
From some posts I have seen this might be a CAS issue - however our IT department suggest the issue might be down to different version of the .NET Framework being to blame. Firstly, is this the issue? Secondly, how can I develop my application to work with different versions of the .NET Framework? Surely this doesn't mean developing many different executables?
The Enable Application Framework Check Box seems pretty well defined in a number oprevious postings, but leaves one question in my mind. The default is unchecked and the sub-topic Check boxes are:
Enable XP Visual Styles - - Checked
Make Single Instance Appllication - - Not Checked
Save My.Settings On Shutdown - -Checked
There are also 3 Combo Boxes:
Authentication Mode - - "Windows"
Shutdown Mode - - "When startup form closes"
Splash Screen - - (None)
When I un check the Enable Application Framework Check Box all items under it are grayed out. However, if I have changed one of the Comb Boxes my selection is also grayed out...My question is, have I lost the use of those function: Specifically I am mos interested in starting my application from a Sub Main and closing the application when all forms close.My underlying question is . . . are the greyed out selections still valid?
I have made a simple vb application and have used vb 2010 to create it, which all of you would know, uses .NET Framework 4.0. I wanted to use this application at work, however, I found out that my work uses .NET framework 3.5 sp1.
So my question is, is there a way to compile something in VB 2010 that will work on .NET 3.5 sp1? If so, how?
For a reason I cannot explain, I now get compiler errors from the Application Designer whenever I enable the application framework in the VB.net IDE. I do not find much on this issue, except Scott Hanselman's admonition not to use this feature. I have mature projects in which this feature was enabled, but now even they will not compile.As this only began a few days ago, I have been trying various approaches to resolving the problem, up to and including removing VS2005 and reinstalling it, along with the framework, SDK, and all updates. No dice. The errors are below.This condition will occur even if I enable the feature in a new project.Does anyone have some thoughts and the cause and resolution of this problem?I probably should mention that I was using both VS2005 and VS2008 on this computer. I had been experimenting with 2008 for several weeks without incident.
If I create an application in VB.NET using Visual Studio 2008, what version of the .NET Framework do other people need to have in order to run my program? Is it the same every time, or does it depend on what the application actually does?
For school i have made an application in VB (Express 2010, .net v4) and when i try to run it at school it says that the .net framework needs to be updated.
IS there anyway of not updating the framework but still allowing the application to run?
I've done a vb.net program. The program basically uses few reference for example system.io etc.In order for my program to run on another computer, the computer need to have .net framework 2.0 installed.Instead of installing the whole framework, can I just pack the references I used in the program together with the vb.net program.? What packager/packer program should I use and how do I go about doing it..?
I am facing problems these days. I have VB Express 2008 with 3.5 .Net Frame Work. I develop applications but my applications dont run on the systems those have 2.0 framework or lower.How can I make my applications to run on all kinds of systems
