Using VB To Test For Presence Of "Save As PDF Add-in"?
Dec 10, 2009
I'm working in an environment (XP SP3, Office 2007) where not everybody has the "Microsoft Save As PDF or XPS Add-in" installed on their workstations. I'm looking for a way to programmatically test for the presence of the add-in within an Access 2007 module.
I was using a loop through the Application.COMAddIns collection to test for the presence of the "Adobe PDFMaker Office COM Addin" but that no longer works when Adobe Acrobat is removed from the machine.
I am currently using the following code to check for the presence of an entry in a table. I choose this code because I thought it was a good idea to use a public function to reduce the amount of code required. It works fine until the field I am checking for contains a' character.I realise I need to use a parameter like @name but cannot work out how to pass the correct information to the public function.how to amend my existing code so I can use @staffNo.
Imports System.Data.SqlClient Dim PaddedStaffNo As String PaddedStaffNo = (TextBox2.Text.PadLeft(4, "0"c))[code].......
I am working on a solution to a problem at work where we can't tell if someone is on the phone or just sitting there. We use Microsoft Lync to place our calls and I was hoping to be able to add a bit of code to an existing .net application to show the presence of the person logged into the machine. That info will send that out via USB to an indicator light I previously built.
So basically I am trying to create a .net version of those 'ON AIR' lights you see at radio stations.
I have been searching for the last few days and haven't found a solution. I also downloaded the Microsoft Lync Controls SDK, but no luck with that either.

I am trying to filter a ListBox based on the presence of a string. Basically, if there is a ListItem that doesn't contain the string then I want to remove all ListItems that do contain the string. Here is what I have tried:
Dim Item As ListItem For Each Item In CtheList.Items If Item.Text.IndexOf("W:") = -1 Then
net application. .exe generated is sufficient to use software. since I have 700 MB (~8k media files) data to include as part of installation I do not want to use visual studio deployment wizard.

I can't seem to get the checkbox checked according to presence of a particular string in a text file. It looks like it should work but it doesn't.
and from VB6 project I reference to Test.dll but an error messege was appear A reference to Test.dll file could not be added (If I create VB NET project and reference to file Test.dll it OK )
Probably a dumb question, but can you write a unit test project in one language to test against another project in a different language?I'd like to translate one of our VB assemblies into C#, but want to build unit tests to verify the results. I've tried to set a unit test project up to do this, but I can't seem to access the VB code within a unit test... I can't figure out if I'm just missing/doing something stupid, or it really isn't allowed.
I am playing with the virtual machine version of the Google Chrome OS. I need a web app that I KNOW is made in visual basic to test to see if it will work with it or not. This will help determine if it's possible to make web apps for this Google OS in VB.
I have a query string called propID and I wanna check if the passed value in it is a legal integer or not to avoid throwing an error that might reveal info about my database, how can I do it? In other words, I want something like -but in vb.net- : IF QueryString("propID").Content.Type = "int32" Then Proceed
Create an app for the DMV that grades the written portion of the driver license exam.Theexam has 20 multiple choice questions. Here are the correct answers to the questions:1=A 2=C 3=D 4=A 5= B 6=D 7= B 8=C 9=A 10=A 11=B 12=B 13=C 14=D 15=C16=A 17=C 18=B 19=D 0=DStore the correct answers in an array. The user interface form should allow the user to enter an answer for each question.When the user clicks the Score Exam button, the application should display a message showing whether each question was answered correctly or incorrectly, and whether the student passed or failed the exam.A student must orrectly answer at least 15 of the 20 questions to pass.Input validation: Only accept letters A, B, C, and D
here is what i have so far: Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
I have a large VB/SQL application that I have created a problem in. I have a table of procedures that have an active flag on them. This flag can be toggled through a user screen. Other screens access this same table to populate dropdowns. The values are stored in the table as the ID field (PK). The problem I have is that I am selecting the dropdown values based on the Active flag. If I select a record that has a procedure stored in it that has been made inactive, I get the old Object Not Set to an Instance.... error.
What I want to be able to do is check for the value in the record when populating the dropdown and allow the record to be displayed by bypassing the SQL error and just showing the dropdown value as blank while not altering the record itself. I hope I'm making sense. Code is below.but I'm back in app programming after being a SysAdmin for 20 years and I'm still rusty.[code...]
How would a person test to see if a usb device is on? I have a program with a usb reader attached to it and would like to throw an exception if it is not on.
I was asked this question recently in a test, which I didn't pass. For the life of me, I couldn't spot what the problem was. It's probably something really obvious as well, but even a colleague of mine couldn't spot it either. The best I could come up with was issues with bottlenecks and naming inconsistencies of parameters! I blame it on the fact I've not done any vb.net for years, I've been doing C# mostly these days

The question: This function, although it will successfully sort a datatable, has a major problem with it.What is the problem? Re-write the function in either C# or VB.Net using LINQ.
I've been looking for a tuto to use resx but I only found some where the resx depends on the localization(and the language of the browser).How can I tell my app to use a certain resx when a certain variable has a certain value.For instance I'd like to use default.aspx.de.resx when xyz=1.

How could I access to Master.LanguageID in this class?
We have a property whose job is to look up a description. If the lookup fails it should show an empty string.
So we can code the property like this:
If foo.bar Is Not Nothing Then Return foo.bar.Description Else

But are there any problems (performance, purity, other?) with just catching and ignoring the error?
You sometimes read it's expensive to throw an exception but I am not sure whether the author means it's expensive to build in exceptions using the Throw keyword (which I am not doing) or whether he means it's expensive to allow exceptions to occur (as I would be doing).
I am building an application to update a database.I have a Map table where row 0 holds the target table field name Row 1 holds an update value or Source table Column name Row 2 holds a Where condition eg
In this example I am going to update the Target Table Field 'Val1' to 25 where the Target Table Rows have Field 'Val1' data > 14 AND Target Table Field 'CustNo' = the Source Table Field 'CustNo' AND the Target Table Field 'Val1' > the Source Table Field 'Fld14' Where I am stuck is I at the moment is wondering how I should convert the strings into test conditions as I iterate the Target Table eg Say my test string is stTest and it holds " = 25" For each dr as datarow in dtTarget
some code
... stFld = "Val1" if dr(stFld) { convert stTest into literal '=' and then 25}
... do something the only way I can think is to build up a series of test cases like:
when I added code to impersonate a user it crashes my app when unning on a new test pcalso data from an access database no longer populates my list boxesso first please help me to pass credentials to teh commands I need to run on remote machines , here is my code so far...
