Hi ya all, I need a bit of advice on this one as I am unsure of the best way to do this :( , so all feedback would be appreshiated. I want to hold who is logged into my application, what I was just thinking was to have a logged in table within my database and when the user successfully log's in then the information is writen back e.g. username, date and time entered, machine number. The only problem with this is a couple of things 1) if my app crashes (hopefully not, but the user might do something strange :confused: ) then how would I ensure that the user is removed from the table? 2) If the user logs into the app more than once (different machine, or on the …

Can anyone point me in the right direction of how to send a message to another user / computer on network from vb.net. I only want to send a message to other users that are running my app. I will store user computer info within a database table i.e. computer name and / or IP address. I have seen examples of sending messages using the net send option, but to be honest I was looking for a way that could display a customised message window rather than the msgbox that net send displays. If someone could point me in the best way to acheive this, that would be great. Thanks Simon

Is there a way to remove the image from picturebox without disposing of the picturebox? A bit like setting a string variable to string.empty? Thnx

I know this subject has been asked lots of times on this forum, but I have a slightly different situation and need a bit of guidance (as always :p) I have an application that when loaded, opens up a login form that just loads connection settings and checks connection to the database. The form obviously loads quickly. This login form allows the user to load two different forms depending on the selection of a combobox, either "Main App" or "Admin App". Now the problem is that both these forms "Main App" and "Admin App" take awhile to load. The way that I can see to get around this is to: 1) Load splash screen 2) somehow load login form (not visible) 3) somehow loa…

I am developing an application which makes the search request via the web service. Meanwhile the progress bar control is displayed to the user. Now, I am using a timer to update the progress bar. As far as I know, the System.Timer should start in the new thread... and here I am having a problem... Start the timer: this.timer.Interval = 100; this.timer.Elapsed += new System.Timers.ElapsedEventHandler(this.cbProgressBar_update); this.timer.Start(); And when timer elapsed, I want to update my progress bar. The progress bar owner is the main UI thread, but the event is raised in the timer thread. So I can't call in cpProgressBar_update method just this.progre…

Hi all, Have a dataset with the following structure: ID, Name, mobile_numb, email_add, message I also have a members table, with the following structure: ID, Name, mobile_numb, email_add, addr1, addr2, addr3, town, county, country, dob, active. The dataset contains some of the records that are stored in the database table. The dataset is loaded from another dataset that is stored in a session that was created and filled when the application was started. What I need to do is to take the records in the above mentioned dataset and compare it with the data stored in the database table to verify that it is upto date and valide. I know that I can do this one rec…

Using multiple forms in the same webform? Is there ANY way to do this in classic asp.net ? Here's my probleme: All my webforms are enclosed with the "<form runat=sever" tag. In this form, I usualy validate the main topic of the page. However, I would like to be able to use other forms in the same page. The other forms dont have to be runat=server, be it'd be a very practical thing. Basically, here's an example of what I would like to do: <form runat=server id="my main form"> //Here's my main form's input <input type=text name=toto runat=server> <input type=submit runat=server> //Here's my second form &…

Building an Asyc Socket DLL using C#, I followed MS .NET FRAMEWORK library sample (see "Asynchronous Client Socket Example") and created a Windows' Form EXE. This .exe has a form which has a button and a text field to invoke the async communication and display return data. <F5>, runs ok and data returned is being displayed.

But, the following comes up in a dialog box, ---------------------------------------------------------------------------- An unhandled exception of type 'System.Net.Sockets.SocketException' occurred i…

<img src="<%=image_path%>" runat=server> ????? This is a very simple question: how do I put a string value into a tag runat=server like this: <img src="<%=image_path%>" runat=server> This simply doesnt work with the runat=server proprety. IIS does not replace the variable «image_path». I need to do use this variable because my images path is dynamic. Please dont suggest me to set the «src» property of the image control in the code-behind class. This is way too messy since I have more than 300 images in my template ascx. I can't just do: myImg1.Src = image_path; myImg2.Src = image_path; myImg3.Src = image_path; myImg4.Src = image_p…

I have a program that basically copies files from a unc path (//myotherserver/path/file.txt) to the local machine (d:\destpath\file.txt) it uses system.io.file.copy however, it says the remote path does not exist - this is because you need a username and password to connect to it is there any way i can specify this username/password within my program code? thanks

Hi, I am familiar with the select function from c++. I wanted to know if someone knows a way to listen to a socket for example with a something like the select function (that has a timeout as well). I need to receive unknown sized data from a socket in a non-blocking way , Therefore I am not sure that using "Socket.BeginReceive" is the best solution for me, because I will want to receive each time one byte because I don�t know the data size, which results alot of callbacks. I don�t want to use "Socket.Receive" because it�s a blocking function and then in case that I will want to cancel the working thread it will be a problem. Is there a way to do something like "selec…

It has been a while since I have done this. How do I navigate through a datatable and get the datarow number of the current record? I thought that it would be something like this: 'go to first record me.BindingContext(dsVeh.Tables("tblVeh").Position = 0 'go to next record me.BindingContext(dsVeh.Tables("tblVeh").Position +=1 [\code] That code is giving me an error though by saying Position is not a member of bindingcontext. And I do not know how to get the current row number of the datatable, only the total count. Thanks, Chester

Hi there. I'm running this website http://www.elefun.net for my company. It is an C# .net solution. Most of the website/product information and user information is based on an Access db. I've got some negative comments about Access db's like: 1. Access db's are bad and should not be used. 2. Access do not handle large db's well. So I've been considering to change to an SQL db for I while, but I really don't know if it's nesessary. My Access db is at the moment about 9MB. My questions are: 3. Is it OK to use acces db's for this kind of solutions? 4. Does Access db's get to large. If they do? When are they to large? 10MB, 100MB, 1GB. I really don't have any cl…
