I have a winform, VBExpress 2008 with a single button and this code behind it to illustrate the problem:
CODE:
When I select a file (in my case small PDF's) I am getting a 3 to 6 second delay after selecting the file until it goes on to the next statement, in this case a MsgBox.
If I repeat selecting that same file a second time, I don't get the delay. But, if I exit the program and re-start it, then I do get the delay again (one time). After the first one hangs it looks like it hangs about ever 7 to 9 tries and the window says "not responding" for a few seconds. I don't have this problem on Vista or XP.
If I select the same file over and over, it might hang the 1st, 2nd and 12th time. Close program try same again, this might be the 1st, 3rd and 9th time. Never the same - as if it is running out of resources and clearing a cache.
I've watched the task manager during the delay and don't see anything unusual coming up. I have a new computer with everything operating properly. I thought maybe it was my Norton Internet Security -- but I turned that off and it made no difference.
How I might trace the source of the delay to the bottom of it? I've tried everything I know to isolate the problem and am running out of ideas. I don't see any other posts about this particular thing.
I have a winform, VBExpress 2008 with a single button and this code behind it to illustrate the problem:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click OpenFileDialog1.ShowDialog() MsgBox(OpenFileDialog1.FileName) End Sub
I know the propertys transparency key and opacity. It isnt what I am looking for. I need to have my form to have the same Glass Effect the as win7 does while runing under win7 plataform. Like, if i have glass effect in the top I should have it in the background.
I have a requirement to consume only the latest two rss feeds (using .NET) to reduce latency in reading RSS. I found plenty of examples to consume RSS. However, I did not find any to limit the feeds being read. And, this is not for a windows forms application.
I have a psychology experiment that has users respond to specific text or pictures by pressing either a button for "similar" or a button for "opposite" and then the program records the time from the presentation of the stimuli to the time they press one of the buttons as the latency. I have the information ans some other data successfully exporting to a text document but would like to have just the latency data also go into an excel spreadsheet for easier analysis. Here is the code for one of my buttons that currently writes to the text document:
i have a very regular problem with MS Access showing random results when being written to from Visual Studio 2008. It happens on all computers including the development machine, using Vista or XP, VS 2005 or VS 2008.Is there a VB.Net flush command I can use before reading the data ?.I write data to a table and then immediately go to read that data.I can make it work if I wait up to 3 seconds before I read the data after a write, using a sleep command. Unfortunately 3 seconds is way too long.Are there any known problems with writing data to MSAccess 2003 from .Net, using VS 2008, VB.Another weird thing that happens is that only half the data is there if I write to an Access table and then go to read it immediately. Sometimes the data's there, sometimes not, with the exact same code and data.
Sometimes the whole table fills with the data from the first record.This is happening throughout my code. Anywhere there's data being written to Access there's a problem if I go to read it immediately after.Sometimes the Access table is blank, even though data has been written to it, and then on a second run of the exact same code it comes good, or gets half the data or every record is a duplicate of the first record. The code is good, so it's not a coding problem, and I can run the exact same code and get good results. So it's definitely an intermittent problem.I run all my access writes through the same code. The part of the code that writes the data is "command1.ExecuteNonQuery()". Whether I read the data from a datatable or as a merged word document, I still get the same problems. So I'm guessing that there's a problem
I have files that start with unique numbers and are word documents. Say the document starts with "1234567" is there a way to make the OpenFileDialog filter to where only all the .doc files that start with "1234567" show up?
Is it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).
i have a application based on Visual Basic platform.. where Enter key action as Tab key ,, which ease the enter key to move from field to field, rather than the tab key.. its works perfectly in Winxp ... but i'm having problem in Windows7 ultimate..
Depending on what component is handling the print for you, some of them are not 64 bit ready (i.e. 32 bit only). To use them you must compile your application as 32 bit only. It will then run on the WOW platform that Win7 supplies.
You change this option on the PropertiesCompile screen. Press Advanced Compile Options and review Target CPU:
I mean not like windows xp which the number and signs are not in the same textbox, but like windows 7 which you can see the whole calculation before pressing equal, and i don't think that compute.datatable can do this because it's limited with the basic signs(+,-,/,*) and it doesn't include the other signs(like : sin,^,root,log), so how to make a calculator like windows 7 one?
this code is for win7 is there a way to work it on xp pro sp3

I used VB6 to create an EXE file that uses MSComm1.The program runs OK in my XP computer and also in my Win7 computer (that has VBE installed).It would not run on my Vista laptop. I installed the VB runtime files (even though Microsoft says they are not compatible with Vista/Win7) but with no success.However, when I installed VBE on the laptop, it now runs the EXE quite happily.Does installing VBE also install a different set of runtime files?Is it posible to distribute my program to my friends who have Vista or Win 7, without them having to first install VBE?
I have used it successfully on 32 bit Win XP VB2008 Express application, but I am having trouble in 64bit Win7 environment.
Specifically the .Connect method is throwing an exception {"The client failed to connect. Make sure the server application is running and that it supports the specified service name and topic name pair."} NDde.DdeException
how to get my vb6 exe to run in any win7 or Vista?The error I'm getting is: Component comdlg32.ocx or one of it's components is not correctly registered or missing. I've tried using the P&D Wizard to specifiy loading it into the SysWOW64 folder but I'm not sure if I'm doing this correctly. I use the P&D Wizard then load everything into Inno for delivery but my customers who now have Win7 or Vista can't use my product.
I am making a windows service that will communicate with a local application through named pipes, and with a server through WCF webservice. So the application hosts the WCF service for the local application, and is a client for the webservices. When trying to run this as a service, the whole thing crashes. I have localized the problem to the "Session 0 Isolation" issue?
�If two-way interaction is required, use Windows Communication Foundation (WCF), .NET remoting, named pipes, or any other interprocess communication (IPC) mechanism (excluding window messages) to communicate across sessions. WCF and Remoting have a better security enforcement that will prompt the user (assuming UAC not shut-off) to elevate if needed. But I am not sure what they meen. As far as I know, i cannot create a windows service as WCF.
I have a vb.net program that is using a voice modem. Well, there is a someweird issues with the modem. (I am trying to work with them but they are kinda slow). Anyway, they only way I can resolve the issues with the modem is resarting the machine. I want to automate this. If I have problems with the modem, I want to reboot the machine and back into windows 7. How can I go about doing this? I am really concern about the login back into windows7. I want to keep the login screen up, but I want to bypass it if my program was the one to restart the machine.
I have looked through more old threads than I can count and I just cannot get any of the suggestions to work. I did a little poking around MSDN as well. I am trying to use the registry to enable AutoLogon on a Win7 machine through code. I can read the current value with no problem but I am running into security problems when I attempt to change AutoLogon to "1". This is what I have done so far.
I have an applcation that sets itself to 0 opacity on Form1_load which then changes to 1 when the user left clicks on the NotifyIcon.I would also like the form to center itself directy above the notifyicon like the Win7 speakers, power, ect popups.
we have a VB6 program and we now make them w7/office2010 ready.
In one part of the program we open the SelectNamesDialog (Adressbook) from Outlook (is separatly from the user startet) to choise one recipent from the list.
Under WinXp the Adressbook automaticly appears in the foreground. In w7 nothing happens. I try AppActivate and by the first call
I have a program for playing MP3 files using Media Player. The program developed originally under Vista using VBExpress 2010 works fine.
But when I run it under Win7 parts of the program don't work. In both cases the audio is played OK but under Win7 the 'playstatechange' events don't seem to happen!?!
I have put a breakpoint in event and under Vista the events happen...under Win7 the breakpoint is never reached. In both cases I am using VB Express 2010 and running under the debugger. I have seen this problem reported before in the forums but no answer was apparent.
I am using socket programming in vb.net to create a server client remoting application. The problem occurs when I use both the client and server in a win 7 box. It works fine for win xp or cross-platform communication (e.g. win xp to win 7). Below are the codes used at the client and server end:
ETA: Using Environment.TickCount does not present the same problem. ETA2: I should add that I don't actually use the Forms.Timer in my app - as this would negate the use of a high frequency timer. I've used it here to simplify the code. ETA3: I've published a workaround as an answer below. I'm having problems with the StopWatch class that I'm observing on a laptop with XP but not a different laptop with Win7. Here's the test code:
I am facing this problem when running my application on 64 bit os .While it is working good on 32 bit OS which is my development environment also. I do not know how to get rid of it. Target CPU is set as Any CPU (there are no other option coming there).
Ok I have a application that works great on XP, but in windows 7 it will not let me write to my login file, says access is denied since I am not running as admin. Log file is located in "C:Program FilesCompany NameProductMyLog.LOG"
I've created a custom DateTimePicker and implemented code I found on the web to allow customization of the BackColor of the dtp (Making use of WndProc). However, I've discovered that this doesnt work in Windows 7 with the XP Visual Styles option enabled in the project. How to make this work for Win7, without disabling the Visual Styles (the controls look ugly without them).
Below is the code I'm using: Private _BackColorBrush As SolidBrush = New SolidBrush(SystemColors.Window) Public Overrides Property BackColor As Color Get Return MyBase.BackColor End Get Set(value As Color) [Code] .....
